Looking at pot of Byblis aquatica that has been dying ever since i moved it
to the Pinguicula window sill, I was all excited because I thought I saw a
new Pinguicula take hold in that pot. Then I looked at some of my other
pings (which for the first time in my 20 years of growing CP have not died
yet and look like they were surviving the winter OK).
Then to my horror, I saw the pot. It looke like some insect had been eating
it. Quickly I came to the conclusion that insects don't usually scatter the
leaves everywhere - it had to be something else...
What caused this plant to look like something enjoyed a wonderful Pinguicula
salad? Well, it turns out that my female Pacific Parrotlet decided that she
had had enough of here own food and wanted to try something else! Luckily,
it was not a prized plant, but an unidentified Ping that has not yet flowered
for me yet.
Moral of the story, if you protect your plants at all cost! Even from Pets
that you think will never be interested in them.
Now to the safety question: Are Pinguicula safe for Parrots to eat? No, i
am not contemplating feeding her more, I just want to make sure that she
won't get sick... Anyone?
Hope you had a wonderful new year.

Hi,
I have a D. montana tomentosa, Serra da Canastra that has started to
send up a flower stalk. It is only about 2 cm in diameter and one of its
siblings, which is a little bit larger, show no sign of flowering (yet).
Do this species usually flower at this size, anyone with experience?
Does it require cross-pollination to produce seed?

Subject: Rampant sphagnum
Hi list & happy new year!
I am in the process of carrying out some much needed gardening in my
greenhouse, to clear away all of the dead material etc.
A large amount of sphagnum moss has gradually been taking over an area under
a bench. Most of this has burried D. capensis & binata plants - what's
that?...you think I should let it carry on growing? :-O.
Anyway, as these CP's seem to grow quite fast, I was wondering how other
people "managed" their sphagnum - should I be pruning the moss regularly, or
should the plants come bursting through the moss again when spring arrives?
Now that I have a bucket full of moss, what is the best way to store it? -
would it be OK to leave it in the bucket in the greenhouse until spring,
when it can be used for repotting (& my Mum's hanging baskets!)?.
Cheers,
A.J.

Subject: Tropical Drosera
I'm just back from 3 weeks holiday. At the start of my holiday I went with
some friends to Litchfield National Park, which is about 150km from
Darwin. I'd seen drosera there a few years ago, and I was keeping a look
out for them, but I didn't see any in what I thought were the obvious places.
The last place we went to in the Park is a spot called the Bulli
Rockholes. This is very popular with the tourists as it consists of a
series of rock pools, through which there is a constant flow of water (even
during the Dry Season). In the peak of the Wet Season, the water is more a
torrential flood.
When we got there, the first thing I noticed was that there were drosera in
abundance. I know very little about drosera. These were all small
rosettes (no more than 2 cm diameter) that were a dark pink-red in
colour. Nearly all had flower stalks (and pink flowers). Possibly they
were d. petiolaris, but I haven't seen a picture of one and only have
a description from the "Savage Garden" as a guide. (If someone could
point me to a website with good photos, I might be able to make a more
positive identification).
They were all growing very near to the water's edge on the slime that
collected around other plants roots. Many appeared to be growing on the
surface of the boulders and these reminded me very much of starfish
clinging to marine rocks.
I would very much recommend this location to any CP enthusiast visiting
Darwin. It's worth visiting for the various pools, and small waterfalls -
the abundance and proximity of the drosera are a definite bonus.
Being a National Park, the flora is protected. I did remove a few dead
flower stalks and when I got home I tapped them over a damp
sand/vermiculite mixture, but I don't really know what I'm doing so if
anything springs up I'll be pleasantly surprised.

In northern Michigan, Pinguicula vulgaris grows in areas called marl fens.
These are calcareous seeps usually in the form of a wide delta along a
stream leading into a lake or the Great Lakes. These areas are open
wetlands, without trees or shrubs, at most a cover of Cyperaceae. They
usually have a characteristic white-ashy colored mud (marl) but are perhaps
even more recognizable by the large numbers of CP present, in particular,
Sarracenia purpurea. Drosera linearis, D. rotundifolia (and hybrids
between these Drosera), Utricularia cornuta, U. intermedia, and Pinguicula
vulgaris are frequently found growing with the Sarracenia, but each in
slightly different microhabitats (on hummocks vs. wet depressions between
them). The Pinguicula seems most particular about its substrate and is not
found in all marl fens, even those hosting the other species. In Michigan
it is restricted to fens along the Great Lakes, but I was surprised to find
it growing in mossy cracks in boulders farther north in Ontario (boulders
are so rare in Michigan, perhaps it would grow on them there if there were
any!) Keep an eye open for Pinguicula wherever you find Primula mistassinica.

Well, you're on the right track here... However, S. luecophylla and S.
flava are both hardy plants. You assumption about S. purpurea is also
correct, *but* some people still believe that the "S. purpurea" from the
Florida panhandle are _S. purpurea_. If you have these plants, they will
not make through your winter outside. The two species that not so hardy are
_S.psittacina_ and _S. rosea_.
Most lump rosea in with purpurea.
If you grow the plants in pots, then you'll really need a cold frame.
Without one, you run the risk of drying out your plants in the dry winter
air. This is a far more important point than worrying about the temps...
An exposed pot with any hardy plant in it is more likely than not to die.
If you follow your plan with the picnic table, I would also mulch them with
something that has a consistentency similiar to wet wood chips in order to
help maintain the pots at a decent moisture level. Check and water as
needed (it's difficult to tell if the soil is frozen or dry) or shovel snow
on top.
Oh, if you still have your Sarracenia inside, it's most likely way too
late to move them out... They would die just from the shock. It takes them
about a month to adjust and get ready for dormancy.

I have a question. What are peoples experience with S. purpurea burkii in a
more northern climate with dormancy? As a grower in Florida I do not
understand that it is often lumped in with S. psittacina as a hard plant to
put through dormancy in more northern locations. Yet the natural range of
S. psittacina goes into extreme southeastern SC along the Savannah River,
where I have seem them myself. Climatically this is in a more northern USDA
zone than the range of S. leucophylla (which shares a deep southern region
with S. purpurea burkii) or S. purpurea burkii (S. rosea).
I am of the opinion that all of these species can take very cold conditions
and are all equally hardy on the short term. I think it must be duration of
cold period (months) that must weaken the plants and allow disease.
The extremes in temperature fluctuation in habitat are severe. From below
freezing to highs in the 70s sometimes in the same day or week. This year
it is very cold, well below normal. But even in normal winters it is very
cold out in the woods in the deep southern Pine Flatwoods during the nights.
I just can not understand how one can pull S. leucophylla through dormancy
in Penn, NJ or Mi and not pull S. purpurea burkii (S. rosea) through using
the same methods.
Take care,

Hi all. How are you?
My absence was caused by Netscape6 (avoid it until it's bugs ae fixed)
so my numerous responses to all those Pinguicula moranensis discussions
never arrived here on the listserver.
Then again, you all missed my best wishes for the new cntury and
millenium, now that it's finally arrived!
But neither point is why I write. No, I write instead because I just
received the new CP Newsletter, or more specifically because of an error
in it.
Now believe me when I say that in addition to being quite unable to
upstage Adrian Slack, I also have no intention of trying (ever!).
However, I was quite astounded to see myslef mentioned in amoungst the
various articles designed to give tribute to Adrian.
I'm a lucky man. I've managed to befriend so many of the well known
names in the CP world. The famous, the technicians, the explorers, the
hobbiests and the commercial suppliers. So I can count Paul Gardner,
who bought Marston Exotics from Adrian, as a friend (though it's rare
that we ever see each other). But I'm afraid my friend has become a
victim of my ability (I don't know how I developed it) to promote
myself. Therefore, I find myself accidentally elevated by Paul from
having been a member of the British Carnivorous Plant society to it's
co-founder - with Adrian!. Oh how I could wish that it were so.
But it isn't and wasn't. From memory, I believe Adrian co-founded the
CPS with John Watson (a now famous British horticulturalist). I'm not
sure if John Sirkett was also a co-founder but he may have been, or
joined almost immediately after the start. I joined about 1 year after
the start. Although I was on the committee, this is hardly a claim to
co-founding claim.
It was an honest mistake by Paul, but I can't let it go.
Meanwhile, well done Barry - its a totally different CPN that pays just
homage to the man most of us "oldies" think of as the father of the
modern CP hobby. Not because he was first (Adrian always owned up to
gaining much of his expertise from others who started earlier) , not
because he was "best", but simply because his book made the hobby
accessible and possible to all. It was a great idea and fun to learn
more not only of Adrian but of those who knew him.

I agree with Mike, I have never had a problem with S. pupurea burkeii, and in
some of the past winters (like the current one) my outdoor bogs have been
solid blocks of ice for a couple of months. I can not remember a single
winter related loss of any Sarracenia in 25 years of growing them outdoors
year round here in Memphis. That includes leucophylla, alata, psitticina,
etc. The only problem ones likely to encounter with winter temperatures is
extremely cold wind chill, so if the bog is protected from the wind there
should be no problem. Our night temperatures here have been in the single
digits farenheit for about a month, and all Sarracenias can handle
temperatures like this with no problem. In fact, I dont believe we have been
above freezing for 3 weeks. But these temperatures are much different than
30-60 below freezing that northern areas can experience with wind chill. The
other problem would be a late snow cover after the plants have resumed
growth. Although April snows have not adversely affected my plants here, cold
wet snow in the spring have been known to cause vft's to rot. Of the
Sarracenias, the only plant I have a slight problem with is alata flowers
which can rot if they experience freezing temperatures after they break forth
from the rhizome. I have remedied this by keeping flooding the bog in late
January to keep the plants from flowering too early.

Dear Mike and Michael,
Both S.psittacina and S. rosea don't seem to be very flower-bud hardy
when grown outside in bogs, in New Jersey. Yes, all Sarracenia are hardy
plants. This is a point I have been telling people for years... These two,
they do not seem as hardy as the rest of Sarracenia. Even when the flowers
do form, they tend to be deformed and most never set seed. These are
symptoms of not being flower-bud hardy in the New Jersey climate zone.
Plants that show these qualilties can be expected to do worst (fewer
flowers, more leaf damage and more deaths) in colder climate zones.
Cold frames were invented specifically for the winter storage of such
plants, among other uses, like keeping woody buds dormant into the growning
season so they can be grafted onto activity growing stock.

Unless you can find someone else with experience growing these plants
outside in your growing area I suspect you are just going to have to
experiment with plants that you are prepared to lose if necessary.
Sometimes its the only way.
I suspect however, that your arrangement will suit fine. With some hardy
plants it is not so much the freezing that kills them but desiccation.
With the soil around the roots frozen the plants are not able to replace
moisture stripped from the leaves by cold winds. Your proposed shelter
sounds as if it will eliminate this problem.
One other thing to bear in mind. Watch out for problems once the thaw
sets in. As the soil thaws it allows pockets of moisture to build up in
the crowns of the rhizome. This encourages botrytis mould, which can
multiply very quickly and kill your plant. With a little introduce
aeration you should be able to minimise this but I would not recommend
you grow S. psittacina outside as this is by far the most susceptible
species.

Subject: Sarracenia dormancy
To the individual who lives in Quebec, here is an idea that may work for
you. In my experience with Sarracenia and cold winters I have grown them
in many climatic extremes. I live in central California but used to live
in Rochester, NY where winers are similar to that of Quebec. If you have
land space available in your back yard you can dig a trench deep enough
to place the pots into and cover them with a thick mulching of leaves,
pine needles, dry peat moss etc. I would first dust the rhizomes with
powdered sulfer or spray with a very good fungicide. Under these
conditions I had noticed that even my flytraps stayed somewhat green
even under the deepest layers of snow. Most of the southern species of
sarracenia are somewhat hardy, but they will be much happier if their
entire root system does not freeze solid. Although they may surpirse
you. This may not be the best solution according to some people, but it
is a safe one. Mulching saved many of my plants in the past.
Good luck.

OK.
Comes a time when everyone has to prove themselves dumb. So to anyone
not already convinced of my idiocy, here's a really dump question that
was prompted by Tommy's "Avoiding mosses growth (pygmea sundews
suffocating)".
Tommy isn't alone, most of us get plagued by moss overtaking a pot. So
why do plants in wild habitats not get similarly overcome by rampant
moss growth? I can't believe it's own to moss eating animals as they
surely would eat the precious plants first. My experience of wandering
in habitats is that moss is not a problem, it does not seem to present a
risk and plants can mature without being overcome.
Any views?

Subject: Numbers (- Time I started another argument!)
This listserver has been very polite for a while! (I wonder if my
absence had anything to do with it?). So, at great risk (we will see if
the risk is realised), I pose the question:
Are CP'ers the laziest plant enthusiasts in the world of horticulture?
Let me cite 3 other groups who rank up there in the clouds with CP'ers,
as fanatical collectors with significant membership of world wide and
international societies. The examples would be for Cacti, Orchids and
Alpine Plants.
In all three cases, look at the plant lists circulated by these
societies, both by members and by the societies themselves, either for
plants or seeds. Then look too at the commercial outlets and the plant
or seed lists they produce. Now compare these with the same for CP's.
See a difference. No? You're not looking closely enough. Try again.
Got it now? Tried glasses?
Ah! Now you have it. All three not only show a plant name, but
whenever possible they show a Collection Number assigned to the plant
when the plant or its parent was first collected in the wild. When did
you see such a thing in the CP world?
This is not a vacuous point just to raise an argument. Some of us like
to hope we are contribuing in some small way to conservation. Should a
plant die out in the wild, we can hope to replace it (no, no no, please
don't restart that argument), even if wee do have to ensure we use
enough material to guarantee genetic variation. But how could we hope
to do that if we don't know a plant's origins? I'm willing to bet that
not one of the professionals amoungst us (paid botanists of any
persuasion: taxonomists, conservationists, etc.) will argue against the
need for Collection Numbers to be assigned to wild collected plants (I'm
not going to get distracted here by discussion of the legality of plant
collecting in the wild).
So, I seriously hope this does not attract trivial or cynical responses.
But I also hope to provoke a serious discussion from all those who
seriously care about the identity of their plants. So I am truly asking
the question: are CP people really as lazy (with regard to assigning
Collection Numbers) as seems true from reading published lists and, if
not, where have all those Collection Numbers gone?

Subject: Re: Dumb Question No. 1
Paul,
Not a dumb question at all. I can only speculate on the possibilities...
First, pygmies in the wild seem to grow in much harsher conditions than we
grow them. How many pictures in Lowrie's books have you seen them and
tuberous and even D. binata growing in pure to almost-pure sand?
Second, are you using Australian peat? Mine is usually Canadian, so even
though peat does come from live sphagnum, it doesn'nt mean that the same
mosses and small animals have to be found in peat from halfway around the
world. I was thinking that the import/export regulations are strict partially
due to soil, and not just plants.
The moss that springs up in Canadian peat is not subjected to the harsh
climates that these plants are, so the spores are well established in the
peat we use, coming from a damper year-round area.
Okay, those are some of my ideas. What does everyone else have?

I don't have collection numbers, but am rabid about keeping collection data

We usually grow our plants in very protected conditions (greenhouses and
similar) and there mosses can grow very well. On the other hand, the
conditions in the wild are very difficult and dramatic: plants have to
resist to horrible weather conditions among which heavy rains with soil
movement and erosion. And there the small mosses can't grow very well
and must fight hard to survive.
Did you ever try growing pigmies on very sandy soil kept outdoors under the
rain? I can ensure no much moss will grow there!
Also in the wild, however, there are places where mosses grow well; in
most of these places CPs don't grow. One of the exceptions is Sphagnum
moss, on which a number of species lives well. But it is not an easy
life: plants have to climb very fast there not to be overgrown by the
moss and they form a slender stem instead of the typical rosette of
leaves which they form on pure peat.
Good growing!

A number of growers consider this very useful and important and keep the
data about provenance of plants.
The problem is that many others are not interested about this and don't care
about the data (in fact this effort is time consuming when you grow many
species); and so many information is lost when the plants are spread among
the collectors.
It would be very useful to define a standard method to indicate these data
so to make it quick and easy.
I'm sure many growers would cooperate when told about the importance of this
practice.
Happy growing to everybody!

Digging a pit to put dormant Sarracenia in sounds like a very good idea. I
have done this, when I lived in Colorado, to create long stemmed Tulips,

this should probably be done before perma-frost sets in. I would think it

I think if you substitute the top 5mm or so of soil with some medium
sized lime free grit this helps with the moss problems though they will
inevitably grow through in a few years still. I have used granite grit
in the past when I can get it as the grey colour contrasts well with the
plants and it is guaranteed to be lime free.
The only problem with this is when starting new plants from gemmae since
there is not much in the grit to retain moisture. Once established the
plant's roots will have penetrated to the peat below the grit. With care
though the gemmae will establish okay.

Subject: Greenhouses: Poly-carbonate versus ordinary glass
I have been a "small-scale" CP grower for some years, with a collection of
Sarracenias and the ordinary Droseras, Pinguiculas and Utricularias. In
order to expand the collection, I have decided to build a regular greenhouse
(approx. 10 m2) in a sunny corner of my garden. However, at the local
greenhouse supplier I was confronted with the question: should it be with
ordinary glass or with poly-carbonate (double layer plates)?
My first decision was to take poly-carbonate as it provides better
insulation than ordinary glass. Since I am living in Denmark, which
occasionally gets quite cold during winter time, this aspect is certainly
worth taking into account.
On the other hand, the poly-carbonate is not fully transparent and I am
concerned about reducing the light intensity.
So, I would be very interested to learn from experience that you may have
with poly-carbonate in greenhouses for growing CP.

Subject: Re: Polycarbonate vs glass
If you use polycarbonate panels you will still get more than enough
light transmission for excellent growth of almost any plant, even cacti.
Unless you experience low amounts of full clear sunshine I would go the
extra mile for the polycarb panels. They also insulate way better than
orginary glass, are resistant to hail or falling obstacles like pine
cones and even baseballs :) and will cut down some on harmful UV. Twin
wall polycarbonate does cost quite a lot, but it is an excellent glazing
material. Most high quality commercial horticulturists I ave ever known
or visited use this material either on the roof alone with something
else on the side walls, or they use it entirely. They must know better
than we do I would think. Again, it is personal preference. Glass will
work just fine but poly has more to offer for permanance, damage
resistance, insulation and UV protection. One more thing....poly helps
break up and distrbute the sunlight rather than allowing it to beat down
on the plants in full force. This would allow for less use of shade
cloth. Have fun with your new greenhouse whatever your decision. Once
you have it you'll wonder how you got by for so long without one.

Dear Thorbj,
Here in the central valley of California we don't have hail but have
intense sunlight eight months of the year so have had the double wall
polycarbonate age and yellow in five years. Also, at low sun angles
(Winter) the light transmission ability of the double wall drops off
because light has to travel through the supporting bars in the
panels. The single wall is more resistant to aging but it does not
have as much insulating capacity. Many commercial people around here
building permanent greenhouses use large span tempered glass. I would
recommend speaking with other commercial and collection people in
your area to see what works best under your conditions. During the
summer we whitewash the glass or have automatic shade curtains to
reduce and diffuse the light. The polycarbonate houses need little or
no whitewash/ shading because the light is diffused which makes the
lighting omnidirectional, reaching the plant from every side
resulting in better more even form.

Hi Mike,
That was me, thanks for the reply. Actually I did get a response
privately and I got the answers I wanted, the small size was not a
problem and this species was self fertile although "hand pollination"
resulted in more seed. I also have D. montana var. schwackei and have
problems with this species too. Grew OK in the beginning, then stalled
and produced smaller leaves (dormancy?). One is approx. the same size as
yours, but the rest are smaller. In my case the problem might be because
of high temperature.

On completing my second greenhouse, I have used the double skinned polycarb
on the north facing side. The reason being that its primarily a safety
feature (with an active young son, it needs to be) and I couldn't afford
safety glass.
The main problem with the polycarb (6mm thickness) is that it flexes to much
and can sometimes fly out of the frame in high winds!
If I was going to construct another greenhouse I would not use this polycarb
again.

Subject: Can you help me?
Hi my name is Holly Beale. I am 8 years old. I am doing a project
for my school's social science fair, called Carnivorous Plants:
Man's Friend or Enemy? I have written a lot of the report and now I
need to do the backdrop which will have pictures and maybe I can
have some sort of model or something fun for people to look at. I
found a great website and the man said that sometimes he had extra
plants to give away but when I wrote to him he said that he had just
given away his extra ones but he thought that maybe somebody at this
email list might be able to help me if they have a plant they don't
need anymore that they could send me for my project. My mom can pay
you back for the postage cost. The only thing is that the social
science fair is the week after next so I would have to get it quick.
If you can send it to me, my address is: 2970 Marlin Circle,
Atlanta, GA 30341. You can write me back at my mom's email address
which is terrybeale@mindspring.com. Thank you!

Subject: U. pusilla?
Dear List,
I hope someone can help... When I was in California for the CP
con, I received a bit of Utricularia. I unfortunately I don't
recall who I received this from, but they said it was a
flowering form of _U. subulata_. Well, I have U. subulata
from many growers, thought I never really wanted it, since all
it ever seems to do is produce cleistogamous flowers (which I
find quite lame). Even the leaves are unappealing to me. I
basically try to avoid spreading this weed into other pots, I
hope it's now isolated outside in my bogs where it grows in the
peatmoss and Sphagnum. I don't have any inside. Well, the idea
of seeing U. subulata with real flowers was appealing.
However, once I took a closer look, I wasn't so sure it was U.
subulata, it just looked a bit more attractive, though nothing I
could point out at the time. When I mentioned my doubt, the
grower was adamant it was U. subulata. Not knowing much about
Utricularia I didn't give it anymore thought. I just thought,
"Hey, if it can actually flower, maybe the whole plant will look
a bit different, being of another strain." Now, that the plant
has grown and flowered I am even less sure. I recently
purchased Peter Taylor's _Utricularia_, he mentions that U.
subulata has subacute end to the leaves, this plant has rounded
ends. Also, traps on subulata are numerous and can appear on
the bottoms of the leaves, not so on this plant. The traps are
sparsely found on the stems, I didn't see any on any leaves.
Also, the leaves are not linear, but they widen a bit near the
end. The flower does not match either of the figures for U.
subulata or _U. pusilla_ in Taylor's monograph. It is close to
both, but closer to the figure for U. pusilla. The spur is
about twice as long as the bottom lip. In the figure for U.
subulata, we are shown a side view of the flower, but not so for
U. pusilla. The spur on my plant comes down and then juts
forward, totally unlike what is shown in the figure for U.
subulata. I almost certain it's not U. subulata now, but could
it still be something other than U. pusilla? What can I look
for to use for ID that doesn't involve using a microscope? Or
must I locate a microscope to look for lots of hairs on the
"oral appendages"? I didn't understand the part about sterile
bracts... What is a bract and the 'raceme axis'?
Thank-you, Dave Evans

I don't have my copy of Taylor to hand but one of the most useful means
of identifying Utricularia species is from their seeds. If your plant is
setting seed I suggest you try this. Of course if it appears to be self
sterile this would be evidence enough that you don't have U. subulata!
You don't need a microscope to see the detail on the seeds. Get a
powerful hand lens or even better a jeweller's loupe. These are usually
10x or more and are excellent for viewing tiny detail as you have both
hands free while using it.
Here in the UK, you can get jeweller's loupes quite cheaply from good
photographic stores - they are used to view slides and negatives.

I wrote an article for CPN some time ago (1974) in which I discuss the
details of scales, bracts, bracteoles, etc. This article is on the web at:
http://www.sarracenia.com/pubs/focus4.html
Basically, the main flowering stalk of a Utricularia plant is the raceme
axis. Pedicels are the little stems that branch off the raceme axis and
hold each flower. Bracts are the little tiny nibs at the base of the
pedicel, where it joins with the raceme axis.
Now, some bracts on the raceme axis are not at the base of a pedicel.
It just looks like a little nib on the axis. This kind of bract, with no
flower, is considered "sterile" (i.e. it is not associated with a flower).
The difference between scales and bracts is subtle. Every bract above the
bottom flower on the raceme axis is a bract, sterile or fertile. Every
bract-like structure BELOW the lowermost flower is considered a scale.

Subject: Drooling Sarracenia
The other day I was looking at my S. leuco 'Tarnok' and noticed an unusually
large amount of sticky secretions, both at the top opening and around the
lower 2 or 3 inches of the pitchers. I've seen this before with my other
Sarrs, but usually it's most heavy around the opening with little on the
rest of the pitcher (with the possible exception of the edge of the ala or
wing). I looked all over the plant and could see no signs of scale or any
other insect pests. There are a few other Sarrs nearby (different species)
but none of them are exhibiting this excess. The stuff is practically
running in drops down the pitchers! Is this normal for this species or do I
just need to look a lot closer for pests? I've never had much of a problem
with pests. I only aquired this plant a few months ago from ABG, but I'd
think they could be trusted to be "clean." Could it be possible that the
conditions I have it in are causing this? It is dormant in a cool spot,
growing under lights with about a 10 hour photoperiod, and probably low
humidity due to forced air heating inside the house.

To all,
Just wanted to ad my 2 cents worth here. I think collection
numbers is a great idea, BUT.... the truth is that most CPers don't care.
How often do we see people growing things which are totally not what the
label says. They simply couldn't give a woof about all the boring details of
taxonomy (which some of us strangely enough appear to feed on) and don't
bother looking it up. Also, no matter how detailed I write down a site name,
I notice how quickly they begin popping up spelled wrong here and there or
appear completely siteless after a while. Furthermore (and I've seen this
happen several times), what germinates is sometimes not what was supposed to
have germinated (some contaminant seed from a nearby pot or mixed with the
original seeds) but is assumed by the less experient grower to be that
species and is soon being traded around by the wrong name. Remember
D.montana? I'm sure there are lots of people still growing spatulata
thinking it's montana. Not to mention all those rosetted African species,
most of which always turn out to be aliciae after a few months. I'm sure we
can all think of such examples for Drosera, Neps, Pings or Utrics. So on the
one hand I think that collection numbers would be quickly forgotten or mixed
up. But then again, numbers are easier to remember than Grao Mogol,

Growing it and selling or trading it! It actually amazes me that growers
seem so naive in this respect. They always assume that whatever it says
on the label or seed packet is correct. Personally I tend to assume the
opposite these days. Until I can positively ID the plant it has a
question mark by it and will not be traded. This applies to both
Utricularia and Drosera.

Oh yes.... The one that immediately springs to mind is the P. ehlersae
that was propagated in huge quantities and sold by several commercial
nurseries as P. cyclosecta for years. It took ages to get everyone to
recognise the real plant and even longer to get certain CP nurseries to
change their catalogue .....

Subject: Nepenthes Pests
Hello Doug and all,
I have noticed several species of Nepenthes tend to be prone to attack by
Thrips. If the underside of the leaves have brown areas, and the sap is red
or dark in color, look with a hand lens or magnifying glass for very small
"," size insects. Very few of these insects, over time, can do quite a lot
of damage, and are hard to see, their damage sometimes being mistaken for
fungus problems. Their life-cycle takes them underground, so a systemic
insecticide, like "Orthene" should be used, following the labels
instructions for Thrips. As for Heliamphora, Scale insects can do a lot of
harm, even in very low numbers. I have never applied insecticide to mine,
but hand removal of visible individuals ASAP is recomended. I'm sure others
have had experience with spraying this genera more than I have.
Take care,

Subject: Collection numbers
Hello,
Steven Stewart again.
I agree with Fernando, (not that I'm an authority, or it matters), but I
also wonder if giving the botanist credit after a species name might help
insure correct identification of material. This information seems pointless
to many, but I have put out a great deal of money in the distant past, for
misidentified plant species. If an individual has looked up a plant name in
a reputable source, (such as the great work done in the ICPS database) this
information should be easy to add, and would help end much confusion over
which plant is which. I would think this information would be more easy to
add than collection numbers, since in the hobby, as well as the science, it
could be consistently applied. Then, if an individual is looking for a
specific collection type, this information could be added. As Fernando has
pointed out most CPer's don't care, until money has been spent for something
other than was intended. IMHO
Take care,
Steven Stewart

Dear Fernando and List,
I don't think it's that they don't care, per se, but rather it's
arrogance. You cannot tell anyone anything without out them getting upset!
I deal with people like this day in, day out. I don't know if it's just New
Jersey, or the whole country (USA), but people are really stuck on
themselves anymore. CP'ers tend to be the best people (as a group) that I
know, and most are indeed interested in details. It's just that our culture
does not seem to value knowledge like it did in the past. Acting like you
know is more important than knowing... Everything is cut and paste, what's
is built from scratch anymore? God forbid if you tell someone you don't
know something though, it's like you're supposed to be arrogant and if you
are not some will feel you're weak. God forbid if you actually had to take
the time to open up a book and read it for knowledge instead of for
titillation.
I do as some other's on the list. If I don't know what a plant is, I
don't trade or sell it. Of course, in the begining I didn't realize how
much there was to learn! I made some mistakes and traded mislabled plants.
Hopefully, I have gotten most everything straightened out by now ;)
I do have a plant that is either _D. burmannii_ or _D. sessilifolia_,
but I don't know how to tell them apart. Jan mentions that the location
data is important. Well, this plant came up in a pot of Sarracenia and I
have not grown either species for a couple years. Yet, it just popped up in
this pot which was not even close to where I had been growing either
species. I don't know how it got there, but now what do I call it if
someone wants some seed: D. burmannii/sessilifolia?

Subject: Re: Collection numbers and "lazy, arrogant" CPers
I had intended to cut and paste from an e-mail but accidentally deleted it,
so here goes:
Fernando said that most CPers are lazy and don't care about keeping
collection numbers. Dave Evans responded that he felt it was arrogance,
that people in general feel learning is beneath them. Actually, I'd like to
propose that it is ignorance. This is the first time I've ever heard of a
numbering system for plants. I don't grow orchids and I don't grow cacti,
or anything else for that matter except garden plants. And my CPs. I
thought you just tried to keep accurate location information and that was
the best way to identify specific plants, and I only learned that by
ordering seeds from Carl Mazur and Phil Wilson. Heck, that seems a lot
easier and more descriptive than some impersonal numbering system.
Honestly, this whole discussion sounds like a bunch of botanists and
biologists whining about amateurs ruining the hobby. Well, for most of us
that's exactly what it is: a hobby. I got interested in CPs as a kid
because I saw these really cool little plants in the store. In other words
- I do it for FUN. Yes, I try to keep location information on my plants
(see my website), and I used to try to keep track of who I got a plant from
until my collection got a bit large (I can still probably tell you who most
of them came from, though). But I think a numbering system would be
intimidating to those who are just getting into the hobby (how many kids do
you know out there buying orchids and cacti?). It would also make it harder
to acquire new plants by trading, because some people won't trade with you
if your plant isn't numbered and registered with the appropriate
authorities. If you want a numbering system, you people who understand
those things have to initiate it, but I think it will de-personalize the
hobby. Personally, I find names like 'Tarnok' and 'Lochness' or "Liberty
Co., Florida" much more appealing than a number (as if I needed one more
number to keep track of!).
If I've offended anyone I apologize, and if you feel the need to blast me
for it, please send replies to my work address where I'll actually look at
them (john.green@ascensus.com) - maybe.

I tend to agree with Phil on this. Anything that comes into my collection
gets a "supposedly" stuck in on the label until I can ID it. I don't trade
Utricularia or Genlisea to other people until it flowers and I have a
chance to ID it.
ID'ing rosetted sundews in cultivation, now that is a subject to drive

Indeed. But since it seems that the editors of CPN are a little busy at

Subject: Neem Oil on Nepenthes, and skyrocketing utility prices in CA
Hi:
I had a problem with scale and mealybugs attacking my Nepenthes and orchids.
So, I put together a mild dose of Neem Oil, mixed with a little dishwashing
soap, and a lot of water, and sprayed it on the Nepenthes and orchids. Two
weeks later, the Nepenthes are doing just fine. They did not die. They did
not even show any signs of problems. Whatever Neem oil is, it either killed
or drove away all the pests. And, my staghorn ferns and orchids survived
the application, too. The only drawback is that Neem oil is rather pungent,
and the smell can last a few days, but it does go away.
As for the skyrocketing utility prices here in California, heating my
greenhouse is making things expensive, particularly where I live, which has
an average of 33-35 degrees F. at night during the winter months. So, I'm
buying a 250-foot roll of bubble wrap, cost $80, to line the inside of my
glass greenhouse. I expect this will drastically reduce heating costs.
And, when the weather warms up in April, I can store the bubble wrap for
next year. Perhaps I should have bought twin-wall polycarbonate instead of
glass, however, all plastics wear out in a few short years due to UV, and I
would have to fork out another $3000 to replace it. At this point, twin
wall makes no sense.
There was a rose grower interviewed on TV who operates north of the S.F. Bay
Area. Last year his December heating bill was $29,000 for all his
greenhouses. This year it's $300,000. The commercial growers would be smart
to relocate their operations near geo-thermal areas, because heating would
then be free. I was in Rotorua, New Zealand, in late 1999, and discovered
that the whole city has free heat. Residents drill a hole 80 feet down and
put in a heat exchanger. Nobody freezes in the winter, and nobody pays for
heat. Of course, living on a dormant volcanic caldera can have its hazards.
The Icelanders do the same thing and they actually grow their own bananas
in greenhouses heated by geothermal. So, if you can locate to an area near,
or containing, warm or hot springs, you can do this as well.
Greenhouse fans generally don't use a lot of power, and mine pulls about .26
amps, which is fine even on a hot day. PG&E has been scaring the public
lately, talking about blackouts and the like, claiming that there is not
enough power to go around. This sounds suspiciously like the gas crisis of
1973, when the oil companies claimed they had no oil. When the price of oil
skyrocketed, magically, there was plenty of gasoline. So, right now, the
partners in this theatre act appear to be holding up a boogey-man doll and
shaking it in front of Californians. And, it's too bad, because if they are
allowed to frighten us into submission, there are a lot of lower income
Californians who cannot afford the rate increases. And what will they do?
As for our government, well, like government anywhere, we have career

Fernando said...
> I think collection numbers is a great idea...
I came to the CP hobby via the killifish hobby (in which I'm still active)
and still can't get over the difference in approach that people from the
two groups have. With the serious killifish keeper, location names and
collection data are generally considered to be very important and with major
efforts being taken to keep even different collections of the same species
apart from each other. The whole concept of hybrids is abhorrent to most,
and fish without collection data are all considered 'Aquarium Strains'.
Generally the point is to keep the fish as close as possible as to what
they were like when first collected.
> Also, no matter how detailed I write down a site name,
> I notice how quickly they begin popping up spelled wrong here
Of course, this happens with killies as well and while it's a shame I
still feel it's important to do your best to keep track of information
about a species and to try and verify it when possible. Luckily with
killies there are several very keen people who have been assigning
collection codes since the '80s and this has become more common during
the '90s as a more scientific approach to collecting and the information
that can be gained from it has been adopted. There is even a book that lists
all the known collections and who made them and exactly where etc.
With certain groups there are also keen individuals who will jump up and
correct people who (accidentily or otherwise) try and distribute fish
with incorrect labels. Brian Watters and the Nothobranchius genus springs
to mind. This does ruffle a few feathers from time to time with people
who don't like to be corrected but that's a small price to pay, IMHO.
Anyay, as I said, it's just interesting (to me) to note the differences in
approach. Certainly with my CPs I record any location information I get
and it's passed on with the plant if I propagate it.
Just my thoughts...

Just as I may label the incorrect origin of a Nepenethes that comes in

As for cactus..... wow what a mess. Very close to total confusion with

Umm, so far all the "alba" plants I have seen are really all-green. I
think "alba" is either a misused latin term or someone though that all-green
plants are albinos and used "alba" to indicate so. Well, they are
diffenitely not albinos as if they were they would not have any green and in
turn die. Some place more importantance on color and feel that alba should
be part of the official name, I guess it's sort of a political statement in
this case.
Yes, an "all-green" plant will have white flowers, since they can't make
other pigments, unless the flowers happen to be green also. I don't know of
any CP's with green flowers though.
If the flowers are some color other than normal, or there is no normal
color (like D. cistiflora), but the plant itself has normal color just note,
"red flower", "white flower", "cream fl." or ect.

Well, I would like to clarify: I don't think CP'ers tend to be lazy and
arrogant, as the subject line might indicate. I think people in general
have become so, rather like it's popular attitude to have. I feel this is
starting hamper society, but enough of that (I am just glad I don't have to
interveiw people for positions). Truly as you mention, laziness and
arrogance are not going to stop CP'ers from using a numbering system anyway
(sorry I got side tracked from the numbering system last time), rather not
knowing how to use one would! I have not used a number system and don't
know the best way to go about building one either.
I would say, though, that many types of CP's don't really need to be
numbered for ease of tracking, unless you want to do a study of distribution
patterns of captive plants! (which would be a massive undertaking, and I
doubt you'd be able to do a decent census anyway) For example: _Cephalotus
follicularis_ is just that, you're not gonna mistake it for another species.
Even the various "giant" clones don't seem much of any different. Just
better cultivated and allowed to grow to their potential. Would a numbering
system that includes location data make it easier to produce seed? For this
species, hardly anyone bothers with producing seed when the cuttings work so
much faster... So I don't think there is much practical use in that case,
but on the other hand we have tuberous Drosera that need to be of separate
stock in order to produce seed (what exceptions are there besides for _D.
auriculata_ and _D. peltata_?). If we want to be able to produce seed of
most of these species, we would need a system that keeps track of clones and
successive generations to keep from inbreeding.
Is a location numbering system worth using for the species that are not
self-fertile? After all, one generation in and you will not have plants
from those locations anymore...
Of course, if we are talking about those small, flat, and red rosette
thingies (Drosera) that no one seems to be able to keep track of, a
numbering system would be very beneficial just for keeping track of the
species. This system would be linear, with the numbers corresponding the
location. Since all of these are self-pollinating, or at least
self-fertile, the same number can follow down the generations from parent to
the seed. It's sound like the easiest (laziest? Devil's advocate here) way
to go for these. Also, I doubt this system would be the slightest bit
intimidating to beginners. Rather the opposite. It would help them to feel
more connected and capable.
After all, how else would we deal with this hypothetical: _D. montana
tomentosa_ was collected at site AX, however, the seed that was collected
included another very similar but different plant. The person who collected
the seed didn't even realize there was another species present since the
lighting was poor as night was coming on. Seed is distributed and some
people are growing what they think is D. montana tomentosa and it looks
pretty close anyway, but it's really not. The seed gets spread under the
wrong name, some people catch it, many don't and there's no way to ever hope
of straightening it out. Had there been a resource (a web page, of course)
for such a numbering system/location data database and the original
collector had registered and distributed the seed under the name "D. montana
tomentosa XYZ", anyone interested could follow this trail. Once the more
experienced growers realize that D. montana tomentosa XYZ is really two
plants and what the other species is and how they differ, the data base
could be undated with this info. Anyone, even the lay-growers, that are
interested in accuracy would be able to follow this lead. Since it cuts out
much guess work and points them right to the proper diagnosis, I think it
would help move them toward an appreciation of the finer points of CP
taxonomy.
How would new locations be added, and would they need to be verified
in some way?

Subject: Collection Data and Borneo
A very emotional subject for all!
I'd like to add my thoughts without upsetting anyone. I have roughly 200
different species and hybrid CPs. From what I can gather,of these 200, 100
should have a ? next to them and by rights I should destroy any seed or
spare plants as I am unable to gather enough information to properly
identify them. I'm an Electrican, just a humble tradesman with a passion for
C.P.s. I have purchased seed and plants from most well known growers and
societies. I keep as much information as I receive with those purchases and
like to think that I can trust these people to have sold me the "right
thing".
I do not sell anything that I am not confident is the right thing but as I
said without the right information, I must believe what I've bought is
right. An example: Every D. coccicaulis I have seen in Australia looks the
same but I was recently told by an educated man (Hi Robert) that it appears
that these are all in fact D. venusta or at least that's what they call them
in the U.S.A. I've sold hundreds of these things! Sorry!
At least if collections were numbered and the numbers weren't lost as plants
were distributed, we would be able to re-name plants as the information
became available and eventually weed out those that were not correctly
labeled.
If nothing else, a numbering system would prop up the C.P. market,and send
those who have to have it all (like me) broke buying them.
I hope some of that made sence to those who chose to read it.

Subject: Numbering of plants.
Time to rejoin the discussion I started. It's always hard to see things revive after Christmas but it seems this topic did it! I'm surprised by good
volume of positive response so far.
First, I have to say John Phillips made a good point. It can be easy to
offend people by calling them names. On this occassion it was me. But
I did it to stimulate a discussion - which seems to have worked. No-one
was personally attacked and those who might have responded worst have
actually just participated. And I only asked a question. Still, I
acknowledge John's point, politely made.
Some people have started to interpret my point, and the responses to it, in way that I didn't intend. In the main, this relates to personally attaching
numbers to plants in a collection, with fears, concerns arising. Before I comment, let me start by adding a few technical terms. I won't introduce
many. And they are very easy to get used to and use, if anyone wants to. (The taxonomists can correct me if I describe anything wrongly,
though I hope not to expand too much as this will add complexity!)
There are two very important "numbers" that can and should be attached
to a plant in a collection. Not everyone will want to do this, but some
will especially if they understand why it's useful. The first number is
called an Accession Number. It need not be a number, it can contain any
characters that can be typed or written. However, it's usual to use
letters, numbers and special characters such as slash and hyphen,
generally all as available on a normal (QWERTY) typewriter or PC
keyboard. I won't explain (now) the different ways these Accession
Numbers can be constructed (historically some were very complex) but
suffice to say that it shouldn't matter (and if you start now, just
stick to a simple sequence. The easiest model or template for using
Accession Numbers is to use the very easy and obvious sequence, 1, 2, 3,
4, etc. The other "number" important to collections is a field
collection number or Collector's Number. This is, as for accession
numbers, another group of characters so it need not be a number
literally. Again, 1,2,3,4, etc. is the easiest to use. There is a
third, less common, "number" which is one assigned to each different
field trip. Often this is just absorbed into the Collector's Number but
it can be a separate value (so if starting numbering now, you can ignore
Field Trip numbers altogether, though advanced users may want to use
them).
So, now I've attached names to the "numbers", when are they used? Let's
start with the one that is theoretically used first. This is the
"Collector's Number". People who actually go out looking for plants in
the wild are those who should (or could) use these. If a person on a
field trip finds a plant, it is normal and good scientific practice to
attach a unique "Collector's Number" to each specimen found. The
collection number is unique to the person using it as that person has no
way of knowing what collection numbers are being used by anyone else in
the world. It is possible that the collector's number is assigned to a
plant on behalf of the collector but by someone else. However, it's
done when or soon after (hopefully) the plant is collected from the wild
and theoretically before the specimen is positively identified.
Accesion Numbers are assigned by anyone (and ideally everyone) who has a
collection of plants. Clearly, if you grow 2 cacti and a poinsietta
(only at Christmas), you won't use Accessions Numbers. But if you want
to collect lots of plants and f you hope to know or label (correctly)
what they are, then Accession Numbers are a good idea. Assigning them
couldn't be simpler. Simply choose a plant in your collection and give
it your choice of an "Axccession Number". "1" is a very good choice but
you could be more exotic and mix letters, numbers, dates, etc. But why
add complications, just start with "1". Then choose another plant, it
makes no difference which, and give it a unique "Accession Number" that
you haven't already used. If you started with "1", "2" would be a
sensible and obvious choice. If you use exotic numbering systems,
remebering what comes next may be difficult. Obviously you just keep
going - 3, 4, 5, etc.
OK. So I hope I've demonstrated that assigning Accession and Collector's Numbers is really trivial. Even if your field trip is into the field outside
your back garden (for those living in the Florida Panhandle, Belize, Western Australia or other CP rich areas), you still attach the numbers. Field
Trips do not have to be formal, planned or to anywhere in partticular.
Next, why use these numbers at all? I'll start with Accession Numbers.
We all know what a pain CP identification can be. Some of those red
rosetty things (er, Drosera), are damned similar! And it would be
stupid to think that all CP'ers will spend hours identifying each plant
in their collection - most will use the name the plant arrived with and
trust it is correct, even though we know that a massive number of plants
are labelled incorrectly! But, let us say that we all suddenly sarted
using numbers. And let me assume I give five of you the same Pinguicula
(with Accession Number 1234) . Now you can assign it your own accession
number (each of you will give it a different one). Now, let's assume I
suddenly decide my Pinguicula is in fact wrongly named. I may not know
who has the plant but I can publish my plant list. Against plant
Accession Number 1234 I can give the correct name (and perhaps show that
this has changed). Now anyone who has a plant that originated from me
with Accession Number 1234 can rename their plant to the correct name.
This is just one use. But it shows that Accession Numbers allow
traceability - you can follow a plant from its current owner back to the
source. A second use, which should appeal to many of us, is long term.
Suppose a plant dies out in the wild. Many of us would like to think we
could try to repopulate the wild. many discussions have already pointed
outv that to try this, you must use as much plant material as possible
to ensure genetic variety is present. But how can you be sure you are
planting different plants rather than clones? The answer is by tracing
a plant's origin using Accession Numbers. This happened with the
"Chocolate Plant" Cosmos atrosanguineus, which did become extinct in the
wild. A world-wide request was made for contact by gardeners who grew
this plant. Each that responded was asked to donate material. All
materiual donated was genetically tested. And each donation that was of
a different genetic variety was added to the group of plants that were
planted back in the wild. Over 90% of plants tested actually came from
a single clone! However, if all the gardeners had used Accession
Numbers, testing may have been unnecessary, saving a lot money.
Collector's numbers also play a part in the smae way. The only real
difference is that a Colector's Number is really a special Accession
Number that identifies the wild origin of a plant. But it's critical
this is assigned and recorded. First, in the previous example (Cosmos),
suppose I trace two plants back to two orignal commercial nurseries.
Are they different plants? I don't know. Probably, but not for sure.
Maybe the nurseries both got their plants from the same collector after
a field trip. Maybe one got plants from the other nursery and didn't
record it. Accession Numbers are assined by each grower so it only
takes one person to forget to record the accession number, r to forget
to record the number assigned by the person they got their plant from,
and traceability ends! But a Collector's Number is assigned to a plant
specimen and should remain with it and all it's clones (or with seed and
all their progeny). So even if Accession Numbers are not used, if we
all recorded Collector's Numbers for every plant we had, we could trace
every single plant we had back to when it was first collected from the
wild. Which means that when a new plant (say P. species nova,
Collector's Number 9876) is actually named, we can all update our
records so that the plant is anamed correctly.
Collector's Numbers are how I started this listserver topic. I would like to think that all wild collected plants could now be given collector's
numbers when collected. I would like to think that those collectors would distribute their plants complete with Cllector's Numbers. And I would
like to think they would ask that those they distribute plants to are asked to maintain the Collector Number so that when they too distribute the
plant, it is accompanied by it's Collector's Number. Obviously this will not affect plants already in cultivation. But it will affect new plants that some
of us are lucky enough to have the chance to introduce.
And even though you might still wonder if you really want to be bothered, I thnk most of you will. Aftter all, when you spend your money on a
plant, wouldn't you like to know it really is what the label says it is? Well Collector's Numbers areyour insurance. Of course unscrupulous people
could invent bogus numbers, but it's traceable and I've never heard of it happening in the cactus or Orchid world, where numbering is common.
So if a plant has an asigned Collector's Number that is published with it in a seed or plant catalogue or in a private list, you can place some trust in
the name as the plant records have clearly been maintained well.
This has only been a simple introduction (it's long enough already!). There is more that can be said but that would, I think, be overkill at this time.
But there no reason why others can't add more in separate emails.
So, how about we have a go at using Collector's Numbers and Accession Numbers? How about we ask plant nurseries (the CP specialist
nurseries) to supply colletor's and accession number details with each plant we buy from them? How about asking our frinds for these numbers
when we exchange plants (or even if they offer to give us plants)? We'll be doing ourselves, and each other, a favour! How about field trip
description being published in CPN (and the other journals) not just with the names of plants seen, but with the Collector's Numbers of specimens
taken for introduction into cultivation (so we know hat to ask for or to look for in the catalogues)? It's up to you. It's a decision each person can
make for themselves. It's a little more work (not much), but it adds enormous value to a collection from scientific and conservation perspectives.
And the financial value of properly recorded plants is also higher!!!
It's just an idea.

John and all,

Looking back at what I wrote, I don't see the word "lazy" anywhere,
so this is your interpretation here John. Read the paragraph below again
please:
"...the truth is that most CPers don't care. How often do we see people
growing things which are totally not what the label says. They simply
couldn't give a woof about all the boring details of taxonomy (which some of
us strangely enough appear to feed on) and don't bother looking it up."
Basically, I'm agreeing with what you wrote:

....

That's exactly it, many CPers couldn't give a hoot about location
info because they're in it for fun. And we can't tell them they're wrong and
that they should do it "our" way. Maybe that's the difference between the CP
hobby and the orchid / cacti hobbies. Excuse my partiality here, but CPs are
WAY more fun to cultivate than orchids, cacti, bromeliads, etc., maybe
attracting the younger crowd and the more informal hobbiest type. Orchids
and cacti (because they're boring compared to CPs! :):) ) seem to attract
more professional/ I-want-the-most-perfect-plant types. And killifish are
probably not as easy to "grow" either, attracting the same type of people.
So I am not being critical towards the "plain" hobbiests when I say they
don't give a damn about taxonomy. I'm just stating a fact, to which they
have all the right in the world to do as they like.

Could be true, but then again maybe the cacti, orchid, and
killifish people said the same thing when it was originally proposed. On the
one hand, I think it'll mostly add to the confusion, that we should stick to
location names and whoever wants to can follow it. BUT... only in the past
few weeks I have communicated with a few CPers on the listserv about plants
that they grew from seeds possibly collected by me. In some cases it's easy
to know if they were really my collections, but some not. A collection
number would've cleared that up immediately.

Subject: New seeds in ICPS seed bank
Sean Samia donated some rare seeds to the ICPS seed bank:
Byblis liniflora, Drosera ordensis, Drosera paradoxa x darbyensis,
and Roridula gorgonias. Quantities are VERY limited.
Sean says Drosera paradoxa x darbyensis won't germinate without GA3
treatment. Please don't ask for the seeds if you can't get any GA3.
I don't have any and don't know where you can get it.
The seeds are listed at

I will not be able to process any seed bank orders until 27 January.
Orders will be processed by postmark date with orders mailed before 18
January processed at random. So there is no point to express mail your
order or send me e-mail about it.
The only exception is for people who have credit with the seed bank
for donating seeds. You may send your order via e-mail and it will
be processed before mail orders. If you want special treatment next
time, send me seeds the seed bank needs. For more info check out the
seed bank FAQ page

I disagree. While there may never be more than one taxon (e.g. a
single species, no wild variants as subspecies, varieties, etc.), there
are separate populations witrh presumably different genetic content. We
do not know if this plant may become threatened in the wild but we do
need to know which plants originate from different locations to preserve
the knowledge of different genetic groups. This would even be importnt
to breeders hoping to generate cultivars, which often depend on
introducing vigour by mixing as much genetic variance as possible from
the correct choice of parent plants.

Which is why we have so few plants that are "different". I'm no hampion of cultivars, I colect species, but
cultivar lovers would like new forms of Cephalotus, I assume.

Yes. Because plants can be produced asexually and then are identical to the parents (clones thereof), so
the collection data is perfectly applicable.

Ah, a like minded soul :-)

No. That would require central co-ordination. It is only necessary for a collector to maintain his or her
system and for each collector to have their own system.
I doubt this system would be the slightest bit

It certainly isn't difficult. If you can write a name on a label, for beginners the "number" would simply be an
extension of the name, another part of the label.

There is potentially such a thing already. Jan's excellent CP database
already helps track previous names of a CP. I would assume that new
species identified by a collection number might appear in such a
database, under their correct name, with a reference to the original and
the collection number. If not, a parallel similar database is perfectly
feasible.

No need. As I said, you don't want central coordination because noone will guarantee its maintenance.
As I've already said, t isn't necessary.

Yes, it does help CP sales as the avid collectors who strive to have everything in their list might feel
obliged to buy plants that differ by collection number. But we already do this anyway as, in many cases,
the collector's number would reference what curently get listed as place names. (However, place names
are not collector's numbers and can never replace them.)

True, but people may still keep data as part of the label without caring what it means. After all, people do
have plants labelled Pinguicula moranensis alba (or Alba or "Alba") but there is no such thing, it's actually
just plain P. moranensis.

And if fun means not recording collector's numbers or accesion numbers, don't. You will not be alone, no-
one will tell you off. It's your hobby and you can run it the way that suits you. But perhaps others will
record useful data if they know how and why. It will not make them "better" people, and it won't make
their plants more valuable to them than yos are to you. But it will make tproperly labelled plants more
valuable generally and as long as you don't care, that isn't a problem. Please - I've gone out of my way
not to criticise your comment here - it's sincere - there's no criticism intended for how you wish to manage
your hobby.

A touch prejudiced perhaps? CPs are more fun if you like CP's. If you like orchids, you probably can't
even spell CD's, oops - I mean, CP's!
No-one is telling hobbyists that it's wrong to not record data. But, and I feel a big argument will result from
this following statement, no-one who collects a plant from the wild should do so without recording the data.
Casual collecting of wild plants is a threat to wild plants. People doing it generally remove lants that are
already in cultivation. People who do it to capture a new species , a new variant or for other reputable
scientific reasons need the data even if they do not yet realise it.
>and cacti (because they're boring compared to CPs! :):) ) seem to attract
>more professional/ I-want-the-most-perfect-plant types.
Clearly there's no such thing. But it tends to be the amatures that
strive for the longest fullest lists. Others tend to specialise so
limiting the numbers of plants appropriate to their collection.
>> But I think a numbering system would be

Yes, kids could be put off if it isn't explained. But I've many years
experience of working with kids. I find that they love to be challenged
and that they are put off by rules when there is no logical explanation
for the rule. Accession Numbering is not a rule, it's a good guideline
that can be explained.
>It would also make it

No, authorities are irrelevent - I'm not sugesting any involvement of an
authority. But wait a minute, haven't you just made my point? If
people won't exchange plants because they aren't numbered, isn't that
saying that numbered plants would be more highly valued? I hink I owe
you thanks for that remark! :-)

So use those names - no problem. And despite what you say, I'd still be interested in plants with no
number. You'd still be able to exchange and run your hobby your way with no criticism (or at least with
none that was fair).

Thank you thank you thank you.
I'm not trying to make a fun hobby boring. I'm trying to explain how a small amount of data that people can
keep - ***if they want to*** can help all of us.
OK. I'm not getting at anyone. Also, cut and paste can result in me
answering a point but incorrectly pointing at the wrong author. I'm not
concerned with who wrote a point - only with responding to the point
made. It's also important to note that there are people out there who
argue just to play Devil's Advocate (I'm often one of them). They argue
to raise the discussion and see what is said - a reasonable approach
that allows things to be aired and answered. So I'm using comments
written as springboards to reply to, not to criticise the authors (whom
I often know well and consider friends - unless they like Drosera)!
It would be good to hear what some of those who consider themselves
"young" or "amature" think.

Subject: D.gigantea asexual reproduction?
Hi, I have a couple of D. gigantea which are doing fairly well but one of
them has started producing small plants from the leaves! I noticed a few
days ago that there were lots of "insects" on the leaves but failed to look
at them properly. Today I examined them and each leaf has a small plant
growing from the center of the lamina. They look as though they have small
pygmy droseras growing there. Has anybody seen this before, is it common?
I shall try and get some of them to grow independently but before I do has
any body had experience of this before and if so, what happened? It is
rather like if I put D. binata leaves in a bag of Sphagnum and they bud off
at the ends.

Hi All,
To make it a little easier I have a suggestion used by our Zoo. If you have a
large collection of various cps it is easier to assign the numbers in tiers
to allow for easier tracking. For example all fo your pings could be 100-199,
the drosera could be 200-299, utrics are 300-399, etc. Of couse you can
assign any numbers but this allows a little bit of easier cataloging and
tracking.

Subject: Collection Numbers
Hello all,
I enjoy all of this exchange of information on this subject, and am learning
a great deal about how numbering plants is supposed to work. I have been
ignorant and possibly caused some confusion in my distribution of plant
material, unintentionally. I always try to be as accurate as possible,
including all information known by me with all plants distributed, including
the original source, if asked. I have attempted, with some success, to learn
how to key plant specimens in Latin, German, and English. I have taken and
assisted College level botany classes, and communicated with knowlegable
collectors, Horticulturists, Botanists, and Taxonomists. I agree to disagree
and understand the concepts of "clumpers" and "splitters". I do not
understand the lack of interest in placing a botanists name after the
bi-generic scientific name of plants.
The reason I bring this up is because the _majority_ of people responding to
my offer of _Nepenthes bicalcarata_ Hook. f. seed this fall, corrected my
misspelling of the species name, because a very popular and informative book
"The Savage Garden" by Peter D'Amato (hello Peter) has this plant named
Nepenthes bicalcurata five times in it's text. This plant is so easy to
distinguish and separate from any other, it is a trivial discrepency, except
for the fact that I was corrected by two people in positions as Directors of
Botanical Gardens! I use Peters book regularly, and tell all I know it is
one of the best written on it's subject. Evidently I am not the only one!
When will the popularity of this new name or synonym make it accepted as the
"correct" spelling? Or is it already?
It is easy to point fingers and find fault with others work, and in no way
do I mean to insult Peter's work. I only wish to point out the importance of
including as much information as possible, including common names, to help
everyone share in this subject, without missunderstandings. If anyone has no
interest in the botanical names, numbers or botanist names attached to your
plants tag, simply ignore them. Also, if my past numbering system, of my
horticulturally produced material, has caused confusion, please feel free to
contact me for explanations.
Take care,

Subject: Re:collection numbers
Tought maybe I should throw in some comments on above. The reason we
don't have collection numbers is because the interesting CPs are
protected, either by CITES or by being inside national parks, and since
we don't want to go against the law we dont collect plants and thus we
can't give collection number, and anybody who says
otherwise..................:-)
I fully agree with the numbering, as it would make trading more
transparent. I myself can't number plants (I think if you are able to
sell numbered plants it would mean you collected enough from the wild to
exceed your needs as a grower. I have seen enough depleted nepenthes
sites to consider this on the borderline of criminal.). On the other
hand I started GPS-ing most of the seed I found lately, so the parent
sites are known. I will also number plants as they become large enough
to sell, and I think this is in accordance with the spirit of the
discussion.

I have heard bad things about Coir here in Florida. Mainly it becomes a

A friend was able to collect some D. gigantea seed while in Australia
many years ago and after growing the resultant seedlings to maturity
found something similar but only with certain clones. These clones would
produce small plantlets in the axils between where the leaves or
"branches" connected with the main stem. How warm and humid are you
keeping your plants? Its possible that a high humidity might cause what
you are seeing to happen.
The diversity within these plants was amazing, even without the
propensity of certain clones to produce these plantlets. Some plants
grew tall and leggy, others were much more shrub-like. Other clones
produced downward arching "branches" etc., etc.

I believe that if you leave the plantlets they will produce dropper
shoots from where they are growing. These will form a tuber when they
have penetrated into the soil. It might be worth removing a few of the
plantlets as well to see if they will root independently.

Subject: Trip to Malaysia
Hello CP List,
I've been lurking on the list for several years now, soaking up the
discussions and information. I just found out that I will be travelling to
peninsular Malaysia for the next month, starting Friday, on a business trip.
I'm going to be taking a week off to see the country, and was hoping to see
some CP varieties in their natural setting. I will be, for the most part, on
the peninsula, but I'm hoping to be able to manage a trip to East Malaysia.
I'm fairly familiar with most CP flavors, however I've never seen a Utric in
real life. Does anyone have any recommendations on CP sites to visit? The
Lonely Planet guide to Malaysia has scant information, I'm currently
scouring the web for anything I can find. Please forgive me if there is an
obvious source for this information in the posts, I've been off the list for
a bit. Thanks in advance for your time, JJ

This may be something different, but I bought a baby D. gigantea (with a
tiny tuber) from Doug Darnowski a few months back. I planted it in a
small pot and put it in a humid terrarium. The original foliage died
back (I don't know if the tuber is dead or not), but while one of the
stems was leanded over, touching the soil, it seemed to leave a plantlet
there. The plantlet does seem to be still alive, so I have good hopes
of at least that part living.

Subject: Seed bank & Collection numbers
Hi John and all,
While we're on the subject of collection numbers, accession
numbers, etc. I thought it was a bit ironic to see a wrongly spelled plant
name pop up in John's e-mail about the seeds Sean donated to the seed bank
(the correct spelling of that hybrid is "derbyensis" not "darbyensis"). Here
we are proposing a whole new way of recording and keeping track of our CPs,
involving many numbers and/or letters, which could be easily tracked through
some updatable database available on the web. Nevertheless we can't even
seem to keep track of correct spelling for the actual species names, when
the answers are all quickly available in the fantastic database Jan put up
(http://www2.labs.agilent.com/bot/cp_home).
I don't want to sound like a picky taxonomist here, but before
we establish anything more complicated for identification of our plants, how
about we worry a little more about the correct spelling of scientific names?
And it's not just the specific, but also the generic names. One of the most
common misspellings occurs with Genlisea. Even in CP books! -- and I admit
it makes me wanna scream every time I see "Genlesia" or some variant. OK, I
admit I still don't know how to spell Triphyophyllum correctly, for example.
But if I have to write the name (like now), I take a few seconds to look it
up somewhere. And the best choice is Jan's database.
Sorry John, I don't want to make a Judas out of you, it was
simply a very opportune example. We see such misspelling all the time on the
listserv and on private/commercial plant/ seed lists. Usually we just let it
pass and forget it. But when we see it in CP books or in CP societies'
newsletters, it really deduces from their credibility in many of our eyes. I
think the most blatant example that I know of is the Japanese Carnivorous
Plant Society newsletter, where plant names are commonly misspelt. Sorry to
those responsible for this newsletter, but I do hope you'll take this as
constructive criticism, to be more careful when editing your journal and
take the extra time to look up the correct spellings, for your own good.
Scientific names are not a cultural or language barrier, they
were created so they would always be written the same way and thus avoid
confusion. You can pronounce them however you want, and this does vary a lot
from place to place. But at least we'll know what you're talking about when
it's written correctly. So as a final suggestion to all seed banks and
newsletters: use Jan's database as your bible and check everything that
comes in. If you're not sure, ask the person who donated the seeds. After
all, it's never been easier and faster to check info than it is now with the
internet (wish I'd had this back in grade school....).

Hi All,
Greg made an interesting side comment about his upcoming trip to Borneo.
Although I dearly love them, all you hear about Borneo is Nepenthes,
Nepenthes, Nepenthes. The only exception I know of is D. "sp 8 Borneo" which
from what I have last heard, has been reduced to a localed D. spatulata.
What other CPs do grow there? So many trips by list members and ICPS
members there. Seems like there should be more than Nepenthes.
I also have a question about Malaysia. I stayed overnight at the hospital
last weekend(nothing serious) and one of the techs noticed my "Borneo
Exotics" T-shirt(great shirts, Rob:) and inquired and I told him about my
hobby and he said he spent time in Malaysia as a kid and remembered seeing "
Venus flytraps" growing in the wild. I told him that it was something else,
possibly a sundew, but he seemed quite convinced and described it as
interesting how it caught insects. Any speculation of what this might be? I
did not think anyone would get a Nepenthes and a flytrap confused.

Help! I want to answer this but I can't (i.e. shouldn't)!!! Surely
there's someone out there who can respond and say why new collections
might not want to do this. I'm ***not*** criticising what is done at
the zoo. Just pointing out there's a reason not to use tiered numbering
systems if you start numbering now. The logic of the response includes
the idea that an Accession or Collector's number need not ("need" is not
the same as "should"!) include any interpretable information (for
example, if you collect Sarracenias and red rosetty things, there's no
need to prefix the Sarracenia numbers with S and the red rosetty things
with RRT, you can number all of them 1,2,3,etc. irrespective of what
the plants are, in any order. Surely someone else can extend this?)
2.
>this is their list:
>DMU0001G Dionaea muscipula Brunswick Co. NC
>DFI0001G D. filliformis ssp filliformis 'Pine Barrens'

In case it's not clear, these are examples of Accession Numbers where
the supplier/owner has identified all plants types by their own
reference number. They do not appear to be Collector's Numbers as they
are not all associated with plants that can readily be identified as
having been collected from the wild (as seen in examples I didn't paste
in above). This is a good example of a published list where numbers are
clear and unique. The format is more complex than most growers need, as
a hobby collection can easily use plain number sequences (1,2,3,4,
etc.). But formatting is entirely up to the person using the numbers.

It's a valid point that both names and numbers can be mistyped. We each have to be careful when we read and then record a name or number. I've received plants from named locations where the place name is written in a foreign language in handwriting - very difficult to read and check! But numbering will help. If
a plant name is accidentally corrupted, anyone can check back to the source if records are kept and eventually, someone will.
But worse still. I once received plants with wild place names written on paper labels in ink. The ink had run as the labels got damp in the post. I could read the plant names but all were P. vulgaris. If the plants had had numbers, I might have been able to read enough to write and ask the sender to re-identify
the source of each numbered plants. Yes, the ink of the numbers could have run as well, but numbers are usually easier to read than hand written place names, especially if care is taken to write 0 and 6 differently and if 7 is written with a horizontal line through it so it can not be mistaken for 1. (Of cousre,
if you type numbers then it should be clear anyway.)
Another point out of this comment (indirectly) was to remind all - if
you receive a plant, say P. gypsicola, from one person and another P.
gypsicola (i.e. the same type of plant) from another person, you
should, if keeping good records, assign each a different accession
number. This allows you to track each plant back to its separate
source. (It allows a lot more as well but 'nuf said on this for now).
Spelling plant names correctly is very important but plant names and
accession numbers are different and serve different purposes. (A plant
can have an accession number before it has a name.) You can share
plants as soon as they have accession numbers as you can publish the
name once you know it, and remnd people that the name applies to all
plants distributed with the accession (or collector's) number of [what
ever it was].
5.
>Don't know, what the name actually refers to, but:

I'm replying to the original question that resulted in the reply quoted above.
If the plants had all had accession and/or Collector's Numbers, this question (the original question, several emails back) could have been answered easily. As it is, none of us (including the person who asked the original question) knows or can easily find out if the plant in question originated from a wild plant,
from a cultivated plant or what name these original parent had. If a taxonomist saw the plant in question, it could be re-identified, though I haven't checked Jan's (excellent) database to see if either "alba" or "All Green" are recorded as legitimate taxa or cultivar names. If not, the whole question is fairly
spurious as we're trying to tie together plants based on names where such names may not be legitimate! If they're not legitimate, you can't possibly know who is using which name to mean what! However, if plants have Accesion Numbers you can tie the plants together if they originate from a single plant,
irrespective of the validity of the plant's name.
Just comments.

With Don Schnell's recent proposal for naming flava varieties, I've realized
that I sent out mislabelled seeds. I sent a post to the list serve to
correct my error now that I understand the difference between rugelii and

Hey Fernando and everyone,
I havent had time to follow this thread but, as far as seed bank
misspellings go, I think it's somewhat of a good thing when no other info is
provided with donations. Why? Well, I know for a fact that Sean knows how
to spell derbyensis and, though he might joke about it, he also knows the
correct spelling of petiolaris. But if there is a misspelling in the name
of a plant thats distributed to a few people, it would be a good idea to
make note of the misspelling. Why? Simply because that's a good way to
distinguish that particular plant from others labelled with the correct
spelling. And if (Ivan got his hands on it and) that plant turns out to be
derbyensis x Dionaea muscipula, at least people can more easily figure out
that that is what they have.... :)
Wouldn't it be great if every false montana communis, esmeraldae, affinis,
etc was misspelled and the misspelling stuck?! then EVERYONE would know to
avoid them cause they'd know they'd turn out to be some weed like
spatulata...
Just a thought.

Subject: education
Not that I'm tired of talking about numbers but I thought I would change the
subject and talk about Holly's and her Mom's visit this past Saturday. When
I talked to Holly's Mom to give directions, we discovered that she lived
just a few blocks away and that Holly attends the elementary school where I
put in and maintain a carnivorous plant bog.
We had the best time walking around and looking at the bogs. It was great
to talk to someone in elementary school who could name the plants in my
bogs. I'm so used to Pinguicula and find it difficult to remember that they
are butterworts but Holly knew butterworts right off as well as pitcher
plants so when we got to the Venus Fly traps, I knew she knew that one. I
was impressed again when Holly knew the difference between an American
pitcher plant and a tropical pitcher plant. And I introduced her to the
scientific names. I was blown away when Holly knew what a Utricularia was
and that she had written about them in her report. We talked about the
aquatic utric that was growing in an old plastic Sprite bottle, and I showed
her a terrestrial utric. We both had a surprise when I held up the potted
terrestrial utric and saw the traps that were attached to the roots that had
grown into the standing water the pot was sitting in.
Yes, an elementary school girl that knows what a Utricularia is is tops in
my book. I then handed Holly a Sarracenia leucophylla pitcher that was
sliced down the length of the tube. Holly pulled the tube apart to expose
the dead bugs and we both observed how the bugs at the bottom of the tube
were more decomposed compared to the still discernible moth resting on top
of all the partially decomposed bugs. Holly was not squeamish about this.
I was quite impressed again. Holly went home with several pitcher tubes,
including a phyllodia, a mature S. purpurea, and several Drosera complete
with caught insects. Holly had handed in her report but talked about
updating it for the science fair to include that Utricularia also grew as
terrestrials.
I put in several plugs that I would be willing to talk to her Dad about
putting a bog in her yard and I would give her more plants come spring.
I suppose this is really a challenge to you folks on the list to do
something where you live to educate kids about cp's. I'd bet the farm that
the elementary school in your neighborhood would love to have a carnivorous
plant bog or cp's growing in a sunny windowsill. CP'ers here on the list
have been very generous and a couple of years when I started the bog,
several people donated plants when I sent out a request so you have a
willing storehouse of cp material even if you don't have a lot yourself.
I'm always good for a few Sarracenia.

Dear Steven,

A plant name you might consider "common" in Florida does not need to
be so common or familiar in Tennessee (or even California, Japan, or
Angola). So in fact the only really common name from a more
general, global perspective (welcome to the INTERnet!) is the
scientific, Latin binomial that can be understood (unambiguously;
if the ID is correct) by us all. A valid Latin name is traceable
information by virtue of the corresponding protologue and type
specimen. This is not the case with "common" names. Using
vernacular/trivial names does not facilitate anything, it
potentially increases confusion.

Thank you very much for your enthusiastic appreciation. But nobody is

list of correctly written plant names; it nevertheless includes a few
typos). Each time I update the cp database, I find errors, typos, or

I would like to take this opportunity (again) to invite all users of

Subject: Collection Numbers & Capensis 'Alba'
The downside to collection numbers is that they are like 'location
names', some people feel obliged to collect them all. And then they
have to buy the book that translates the numbers into field locations.
Of course, in an ideal world, every plant would come with its complete
genome mapping, but that might be a bit long to write on a label!
I understand the white-flowered form of capensis was described in the
British journal many years ago, and the 'Alba' designation is not
valid (although everyone understands it). In my own experience,
although the foliage stays green and the flowers stay white, prolonged
sunshine can cause the glands to go pinkish.

Hey Folks,
Not too sound sanctimonious, but....
One reason that the characteristics of the so-called Drosera capensis
"alba" may be difficult to figure out is that this is an invalid cultivar
name that has never been established or registered. So with no published
description, there is no way to tell whether the "alba" designation is
intended to describe the flower color, the pale tentacles, or perhaps the
color of the roots in cross-section! :)
Of course, I am aware that the name is used to describe a plant that has
white flowers and very pale tentacles. The correct name for this plant,
though, is Drosera capensis 'Albino', as noted in the ICPS cultivar
database at:

Subject: Drosera F2 hybrids
To all,
John sent me a private mail regarding that petiolaris-complex
hybrid he received from Sean which posed a few interesting questions in my
mind. I thought it would be interesting to discuss it here. John said Sean's
seeds may be an F2 or even F3 cross of those two species (derbyensis X
something, I can't remember) and wondered how the offspring would look, how
the characters would segregate.
A few years back I did a lot of Drosera hybridization, obtaining
several fertile crosses. Strangely enough though, I never noticed any
segregation among the F2, F3, etc. Weird, isn't it?? I would expect to see
something like in Sarracenia where you get the whole spectrum between both
parents. Could this be do to the fact that I was crossing tetraploid African
Drosera (2n=40)? Since everything was already duplicated, maybe this somehow
buffered the segregation effect.... Any ideas??
Now with the petiolaris-complex, I have no idea what happens
with F2, F3, etc., since the chromosome numbers are a bit odd in this group.
Has anyone noticed segregation of characters in the F2 generation in any of
these petiolaris-complex hybrids? Or with any other fertile Drosera hybrid?
Best Wishes,

Subject: Re: Coir for Nepenthes
I've used coconut fibre chopped up into small (few cm) lengths, but I mixed
it with other ingredients such as peat, fir bark & charcoal.
It lightens the potting mix and has lasted at least a year in tropical
conditions. I find the chopped fibre is awkward to handle when it's wet,
as it tends to clump together.
I started using peat bricks a while ago. The label says that they contain
coir fibre (which binds the brick). It was only when I looked up a
dictionary some time later that I realised that coir is coconut fibre.
It's interesting to split open a coconut that's sprouted. Inside is a
large seedling virtually sealed in a container of fibre. One day I'd like
to try and grow a Nepenthes in a coconut that's had its seedling removed.
BTW, can anyone point me to specific growing information on N. ampullaria
(eg old digests)?

Subject: Mushrooms
A few months ago, mushrooms started growing from a pot containing two N.
maxima x veitchii (xTiveyi?).
I identified the mushrooms as Armillaria mellea, or the Honey Fungus, a
widespread parasite (particularly conifers).
I transplanted the two plants to separate pots, but they got really spotty
and stunted. The larger plant looked so bad, that I transplanted it again
this time to a garden bed outside (the soil here's really barren). Both
plants are still alive and the one in the ground has grown a couple of new
leaves which are small but are free of the brown spots.
I mention this because more mushrooms are popping up from a pot containing
a Bougainvillea. They're really spectacular and more interesting than the
Bougainvillea. If only I could get them growing regularly. I'm sure there
would be a market for boutique ornamental fungi. If anyone wanted
Armillaria mellea spores, I could probably collect some (only joking).

Hello Jan & list
I thank you for your welcome for me to the INTERNET. I in no way wish to add
to confusion that is already so apparent. I also would like to thank you for
all of your enlightening work done to help end confusion on your CP
Database. I use it often.
In the past year I have discovered an overwhelming number of people who
still call a meter tall Nepenthes bicalcarata, a hanging Flytrap. You may or
may not care, I am no longer attempting to operate a plant business, that I
produced many different types of plants, some CP and some not.
When trying to open markets to large retail customers, I was told to name
the CP, "Hanging Flytraps" (Nepenthes), "Upright Flytraps" (Sarracenia),
and "Venus Flytraps" ( Dionaea, Drosera, Pinguicula, Utricularia, Genlisia).
Like it or not, business does play a part in education and education is big
business.
In any case, I do realize over use of "common names" does confuse matters in
the long run. But thank goodness the world is familiar with the "common
name" Carnivorous Plants! These plants, and all information about them,
would all be very obscure without it.
Take care,

It is not established (cultivar names must be *established* before

because it is simply not the name published in 1989. The

It depends. Obviously there *is* some confusion (see previous
messages on this topic). For _Drosera_ ' Albino ', there is a
description and a standard (=prerequisites for registration), so
everyone who can read and see should be able to understand what the
name means.

Hi all:
I just installed bubble wrap inside my glass greenhouse. The greenhouse is
now keeping its heat. Cost was $67 for a 12' by 16' greenhouse. All you
have to do is tape it to the frame with clear packing tape. The bubble wrap
provides excellent insulation, and is a nearly no-cost alternative to
expensive twin wall polycarbonate. At this cost, you can buy new bubble
wrap every year. Or, if you're careful, you can take down the bubble wrap
in the spring and store it for next winter.

Why take it down at all? It is for insulation, correct? Won't it help keep

Thank you!

Ugh! You are stretching my knowledge to breaking point and I hope a
professional taxonomist with field collection experience will step in
any answer the question (hint hint)! Meanwhile, my view is as follows.
Logic dictates that the seed should not in fact be collected as a
mixture if it can be avoided. But if we assume it is, we should also
assume some effort is taken to collect seed from what appears to be a
single type of plant (i.e. one species). Then the seed is given a
single Collector's Number and distributed with that number. If it later
transpires that two species were mixed together, at least the attached
Collector's Number will aloow both species to be traced back to their
original point of origin in the wild.
As a mixed collection (i.e. different seed in a single packet) is far
from what would be expoected of a feld botasnist, I suspect there are no
published "rules" for dealing with it. It might therefore be
inappropriate to start separating out the seeds and try to package them
separately, but where the seed looks different this might also be a way
of proceeding as long as each packet is labelled with a Collector's
Number and as long as each Collector's Number relates to well kept data.
But I repeat, I'd like a taxonomist with field collection experience to
comment too.

Nice idea - but all you'd end up with are lots of different plants
sharing the same incorrect name. Only plant numbering (Collection
Numbers and Accession Numbers) will ever resolve this, which is exactly
why they were devised.

Perfectly valid point, but a different subject.

Agreed. But then that is the fault of the person electing to do so. I
realise that some people collect in order to attempt to have the longest
list, somehow thinking that this equates to the best or most important
collection. But beauty is in the eye of the beholder so a long list to
some may simply be a bad list to others. (e.g. a Pinguicula list
containing just 20 different types of P. moranensis may be 20 different
plants to one collector but just one plant to another). I certainly
hope we don't avoid numbering just because a few people might feel
obliged to collect them!

Oh no they don't! I say again, how can anyonme understand what is
undefined? There is no published definition for what is meant by D.
capensis 'Alba'. If there was, it would be an established name. As it
is not published, be definition no-one has ever described what is meant
by it. So anyone can assume they know what is meant, but no-one, not
even a single person, actually knows what is meant by D. capensis 'Alba'
unless they personally attach the name to a plant that arrives without
such a name. And if they do attach the name themselves, they can not
possibly be doing so based on another plant they know of called D.
capensis 'Alba' because they can not know what features that other plant
has that are specifically identified by the unestablished name of D.
capensis 'Alba'. (Sorry Nigel - not having a go at you - you know me
enough to know that.)

However, no-one has yet pinted out, so I will, that it would be entirely
incorect for everyone to now pull out their D. capensis "Alba" (or is it
"alba") labels and replace them with D. capensis 'Albino' labels. This
can only be done correctly if people first read the description of D.
capensis 'Albino'. They would then have to compare their plants
labelled D. capensis "Alba" (or "alba"). Only if their plants met the
description of D. capensis 'Albino' could they then replace the labels.
In fact, it's my belief that without taking the trouble to identify the
plant, collectors would be doing us a favour if they maintained their D.
capensis "Alba" (or "alba") labels so as not to further muddle us all by
distributing plants mis-identified as D. capensis 'Albino' without the
benefit of any process of identification.
> Wouldn't it be more appropriate to refer to this form as 'anthocyanin free'
No because the apostrophes written as you have indicate that the name is
intended to represent a cultivar and no such cultivar is registered.
There are rules on what names may or may not be used as cultivar names
but as long as one obeys a rule, the rules do not include definition of
what is more appropriate. Thus, if a plant is very red, a cultivar name
of "Brown" can legitimately be applied (I think!) even though, if colour
is indicated, it's clearly inappropriate (unless you're colour blind).
> or 'low anthocyanin' D. capensis?
No because you can't place a cultivar name before the Latin name. If
you reverse the order, the previous reposne (previous paragraph)
applies!

Oh ok, since no-one stepped in. (Now where did I put my safety net?)
I understand the benefits the zoo gets from treating the data in this way. However, for someone starting a ***new*** recording system I would still recommend a non-tiered system. If a pen and paper system is being used, a large collection would become unweildy. If a computer system is being used, the system itslef
should manage all groupings for the user such that there is no need at all to worry about two related members of the collection (accessions) having similar or related numbers. So, to put it in CP trms, suppose you have 100,000 specimens that are each different by way of name, cultivar or wild source location, i.e.
100,000 different specimens. Let's suppose there are equally numbers of Sarracenia, Nepenthes, Pinguicula and Drosera and that you have less than 10,000 of each. You could have all Pings as 10000 - 19999, Neps as 20000-29999, Sarras as 30000-39999 and Dros (pertinent acronym?) 40000-41000. This in theory makes it
easy to search within a group. But any good software would easily know which records related to Drosera even if the numbering of Drosera specimens was completely random.
However, note this only applies to new attempts to start a numbering
system. I would not recommend that an existing large collection be
renumbered randomly to replace an existing tiered system.
Cheers

Hi Fernando and all,
I have done alot of hybridizing though most crosses I have made are not
fertile, still, I think I have it figured out. The traits of leaf shape
are not strict Mendelian traits as flower color often is, and so you do
not see predictable dominant and recessive segregation ratios. I guess
this is because the traits of leaf shape are the expression of multiple
genes. Mendelian traits are single gene. Crosses I have made in some
South African sundews (which proved to be fertile) and also with my
fertile polyploid D. x nagamotoi, I saw variation which might be of the
same pattern as with the petiolaris complex hybrids. In the first
generation most of the hybrids were about equally intermediate between
the two parent species. The second generation selfed offspring were much
like their parent though some varied a bit to appear like one or the
other parent species. Following generations when selected for a specific
appearance became less and less varied. My D. x nagamotoi now in its
fifth generation seems to have stabilized.
Above I said that the hybrids are about equally intermediate. This
means that an averaging formula can be used to predict what most of the
hybrids will look like. Take for example my D. dielsiana X D. nidiformis.
The D. nidiformis parent has longer more slender leaves than D.
dielsiana. The average of leaf length and width can be found this way.
Measure the lengths and add them together and then divid them by 2: L1
+ L2 / 2 = L3. The length L3 is the hybrid, simple:-)
On this note, Petiolaris Sean's computer is still down. BTW, Sean does
know the correct spelling of D. derbyensis and also I'm sure he realizes
this plant originated in Derby, NT Australia. I'm on to him, ...he uses
these tricks to test our humour. Sorry to let the cat out of the bag:-)

Well, I'm not a taxonomist, but I am a seed collector, so here
goes...
Usual practice is to select a large population of a single species
and to collect 'randomly and evenly' (this is actually a
contradiction, but never mind) across the whole of that population,
in order to pick up any genetic variation at that site. In the case of
extremely rare species, seed from individual plants is bagged
separately, to preserve individual gene-lines, but generally seed
from a single species/site will be lumped.
Each seed collection (at the Millennium Seed Bank, at any rate)
will then be assigned a unique accession number on our database,
which refers to that collection and its accompanying field data. So,
one accession = one species from a named site, collected on a
specified date, by a named collector.
If seed from individual plants is collected separately (see above) all
the seed-lots will be given the same accession number, but will be
stored as separate lots, ie. never lumped together.
Hope this helps,

Ok, Nigel, I think I understood your point of view. But, I

numbers into your means (field locations, collectors, collection
date, etc...), a way to avoid it may be publishing the original
numbers list on internet, who knows at ICPS site or even at CP
Database site (what's your opinion Jan? ). So, all people
could have access to the list, and, what I regard very important, a
"universal" list. The point is everybody should follow the same
list, this is very important.
I've had some problems in my collections. I've received
some seeds with no locations. I have used them to my study, but I
know I will face problems in future. I try to choose that ones with
the maximum of informations, but sometimes the only information is
the species name, sometimes misspelled... Well, I agree Jan, it may
happen with all us, besides you Fernando! :-) :-)
A important point is a numbering system could be the chance for
the plants be used to genetic studies. For instance, _Drosera
brevifolia_ from North America, definitely, is not the same _Drosera
brevifolia_ that occurs on Brazil's fields. Two populations of
a same species separated by even few kilometers may be very
different genetically. To people that consider the possibility of a
more serious organization of our collections could loose the "fun
side" of having a collection, I don't think it's the case.
A more organized system does not mean a more complicated one.
Otherwise it could facilitate our lives, tracking a mis-ID species
that we may have in our collection, even after a long time. So, as
it was already commented, that number (that species) will be avoided
for all us after the notice.
Well, just some ideas. All of us will gain with the benifits of
a numbering system, no doubts. I think we have to discuss about it
a lot yet.
All the best
Vitor.

I'm quibbling about a millimetre or two here, but it seems to me easier
for a large plant to lose a certain length from its leaves than it is
for a small plant to gain the same length. Is it possible that where

Yes, the old D. aliciae instead of D. sessilifolia trick. I had some

popular seed to be mislabled as such. D. sessilifolia( I am
responding from work, so if I mispell it, forgive me) is an annual
from South America and looks rather similar ro D. burmanii and there

I'm sure it's not a simple mendellian cross with one gene
involved. Just as it's most likely not simple eithr with
Sarracenia or Neps. Yet it seems to me that we see more
variability and wider distribution of characters in F2 crosses of

There is, as far as I understand the ongoing discussion correctly, no
defined set of data that should "at least" be linked to collection
numbers. This makes identification of the taxa corresponding to
collection numbers impossible once the plants are no longer available
(things that may happen in cultivation!). If collection numbers were
backed up by e.g. herbarium specimens, there might be a way to link
them with taxonomic data as listed in the cp db. Anyway, this would
be an enormous task, and I have other interests at the moment, viz.
providing a mapping function with the database browser and including
systematic information for more sophisticated searches and
statistics.

Certainly. Anyway, a complicated case. I have seen the epithet "alba"
first in Peter D'Amato's book. But it seems he has only cited Paul
Gardner. In its Latin form, "Alba" is clearly inappropriate for a
cultivar epithet (which must be from a modern language).
Additionally, it would probably be difficult to distinguish such
plants from the described cultivar _Drosera_ ' Albino '. Anyway, it
is (without a typification and without a Latin description) only a
nomen nudum without any nomenclatural meaning.

Because of its Latin origin, it is not a cultivar name (the quotes
are immaterial). It is a nomen nudum (i.e. its rank is undefined,
anyway). If the rank is not noted in the original publication, such
combinations are usually interpreted (at least in the cp db) as
varieties.

Subject: Re: more about collection numbers...
I've been watching the thread on collection numbers, and noticed that cacti
people were cited as having a good number system. since I'm more of a
cactus person than a cp person anyway, I feel some obligation to introduce
you all to some resources available for cactus collection numbers (if
you're really that interested :-)
This is a web page for one of the cactus & succulent nurseries that sells a
lot of seed and plants with collection numbers and locality info. See:
http://www.mesagarden.com/ra2001.html
Scroll down to "Copiapoa". Numbers on the left are assigned by the nursery
and could be considered their own accession numbers. I don't think cactus
collectors prize these numbers, undoubtedly some do record them. But see
those KK numbers, like KK1386? Those are the numbers that cactus
collectors covet. What do these numbers mean?
Go to this site:
http://ralph.cs.cf.ac.uk/cacti/collector.html
This is a web site for collector acronyms. Enter KK and it tells you this
is Karel Knize, of the Czech Republic, resident in Lima, Peru. Some early
collections were made under KZ numbers, but these are independent and do
not coincide with the later KK numbers. Knize has produced two official
indexes of his numbers. The 1967-1977 one covers the numbers KK 1 - KK
1471; the later 1967-1987 index covers KK 1 - KK 2000. These lists do not
always agree entirely.
Most collectors do not have such detailed info, but Knize was one of the
most prolific collectors.
Now try:
http://ralph.cs.cf.ac.uk:591/fieldno.html
This is a web site for locality data. Try KK1386. Your results:
Field number: KK1386
Collector: Karel Knize
Species: Copiapoa sp.
Locality: El Tigrillo, Chile 100-400m
Notes: (C. coquimbana v. deminuta n. n. in 1977 list)
You get back some locality info and also an annotation of the current
identification of this plant originally listed as a "sp.". Again, this
level of information is not present for all collectors, but special
attention has been paid to Knize.
This locality information was previously found only in some very obscure
cactus publications (ie. "The Chileans"), or on some lists with limited
circulation. A few dedicated cactus enthusiasts compiled this info and
made it available on the web, so you can get this data for that plant you
have with the mysterious KK1386 number on the label.
As a caveat, I must point out that there is no guarantee about the pedigree
of your plants, which have been maintained and seed propagated in
cultivation for several decades now. You may collect seed from your KK1386
Copiapoa, but what plant was the father of that seed? How careful was the
last grower? (cacti are mostly obligate outcrossers).
Interestingly, there are few cultivars in the cactus hobby (outside of the
epiphytic cacti), and in practical use the plants bearing these collection
numbers are treated as cultivars.

No numbers here!
Just to acknowledge the replies following my being asked if Marston's catalogue mention of the name
counts as establishing the name.
As someone answered, I'd prefer to leave that decision to Jan who is the
(undisputed?) expert. I don't track cultivar publication and relied on
someone else's statement that D. capensis "Alba" had not been
established as a name. Now that Jan has no doubt seen the references,
I'm sure he'll update the database if required.
As a separate point of personal interest - I'm not actually sure what to expect if a cultivar name is
"published" but is not considerd established, for example because the name already exists in that genus or
because insufficient description is given to allow association of the name with some known appearance or
because the description given in no way allows the cultivar to be distinguished from another previously
described cultivar. Is the name ignored? Is it recorded as an equivalent of an invlaid name? Is such a
name barred from future use as it's use has been inappropriate? Beats me!
As to me and naming, I'm dead careful ever since I foolishly believed a list (Harald Weiner's catalogue)
that called a plant he was introducing to cultivation Pinguicula alfredae. The plant is of course P.
heterophylla and publication ofa species name in a list is not valid so doesn't count (unlike cultivars).
Since I published the P. alfedae species name in a book, I of course get credited with making the first
formal publication of the name, and i therefore get credited with making the error!!! May the next plant
name I mention be more rigorously researched before I publish!!!

There was someone doing research on this subject in Canada but I can't
remember his name and I've no idea if he eventually published any
results. Not a great deal of use I'm afraid but one of his and my
thoughts was that one means of seed dispersal is during periods of
flooding - Sarracenia seed floats of course. Seed in habitat that is
liable to flood will likely be dispersed while the area is in flood, the
seed being deposited when the waters recede.
This means of seed dispersal would not surprise me at all, at least in
the northern bogs, which are very prone to this type of flooding.
There are weaknesses in this idea though. For a start there are many
sites in the south that are probably far less likely to flood, though
having never visited any of them in the winter this may be an incorrect
assumption.
Also, the flood dispersal argument does not explain the wider range of
Sarracenia species, with pockets of habitat surrounded by areas of
unsuitable land. Probably there is some sort of animal or bird
involvement in the seed dispersal as well.

Subject: Re: And still more Re Numbering
I'll just add a bit more to the numbering discussion form a horticultural
point of view albeit not in CP's, but orchids...
As the orchid collection of my parents grew and grew over the years and
with the start of our own propagation laboratory we needed to change our
way of dealing with our plants.
Just as a sidenote: 99.9% all crosses that we make our between plants of
the same species.
The early crosses when I stepped in as "bumblebee of the greenhouse" were
simply recorded using whichever indication that we had available: country
of origin, flower colour, position in the greenhouse, ...
e.g.
"species x" (dark) x "species x" (big flower)
"species y" (cool house) x "species y" (intermediate house)
"species z" -Honduras- x "species z" -Mexico-
I'm sure you can spot some problems with these indications.
- we received another dark flowered "species x"
- we have multiple clones of "species y" in the cool house
- we have multiple clones of "species z" from Mexico
So we needed a better solution !
1st try -> lets number each clone within a specific genus/species
combination sequentially. e.g. "species x" (1), "species x" (2), "species
x" (3)
Problems with this approach: the biggest problem is very simple, after
flowering the "species x" (2) is no longer "species x" but "species a". So
you cannot trace the complete history of your plant throughout the years,
unless you copy/paste all relevant data and keep track of each and every
change -> at that point your plant has multiple IDs, which is not good at all.
2nd try (and this is where we are know) -> number each clone and give it
a unique sequential number. This number is simply composed of the
following: "letter indication" + a seperation dash + "a 5 digit number".
e.g.
[AO-01000]
[AO-05426]
[AO-08912]
This approach allows us to track down a plant throughout the collection
without problems (only collection plants are numbered of course).
The [AO-01000] will tell you nothing about the genus/species it belongs to
(as misidentifications happen), but it allows you to trace all information
belonging to that plant and only THAT plant.
What does the "silly" letter combination stand for ? AO = Akerne Orchids
Why the need for a 5 digit number ? When we started registering the
collection in this way, we figured we had some 8000 plants/clones so it was
not unlikely that in a few years time we would cross the 10000 mark. 99999
on the other hand is something that we will never reach (unless we expand
enormously... who knows ?)
The dash in between is just for easy reading.
Basic rules:
- no number is ever re-used even if the clone is question dies (very
important !)
- use a fixed length numbering system. if a friend comes round and says
that his [AO-168] has flowered and that it was not correct, then we can
tell him that his reference is not correct... It should be something like
[AO-99999].
Advantages:
- when you exchange divisions of a specific clone, your friends can always
trace it back to you because it is numbered
- because the numer is unique, we are always talking about the same clone
Disdvantages:
- no direct link to the genus/species combination in question, but for
orchids this is not bad, even an advantage: today its an Oncidium
something, tomorrow we should call it Psygmorchis something else, and so on.
I don't know about other plant families, but some orchids have a habit of
changing names every now and then.
Why not tiered (like 10000 -> 19999, 20000 -> 29999, ...) ?
- a plant number 10000 al of a sudden turns out to belong to the 20000+ range.
This problem is less likely to happen within the CP area, a Drosera is
quite distinct from a Sarracenia, but other plant families are not always
that clearly distinguished.
From time to time unidentified species will enter our collection. All we
know at that point is that it is "an orchid". Defining the genus is often
troublesome with some 30000+ species around.
- some genera are monotypic, but then again a new species for that genus
maybe still be discovered...
> Is there a system for
> numbering collected seeds from a wild population when the seed from a
> population are mixed.
I liked Pauls explanation, especially the part about collecting seedpods
from several clones. My views exactly, seed from one clone should be kept
seperate from seed from a second clone.
Are you sure that the pollinating insect made the reverse cross ? like in A
x B and B x A, or was it so "dumb" as to create A x B and B x C...
When we collect seedpods, all seedpods from the same clone are treated as
the same seedbatch. Yes, we are not sure that every pod was pollinated
using the same parent !
But that is, for us, an acceptable risk, since pollinators of orchids are
in most cases quite specific insects, even within the same genus !
To get back to numbering. Well, this (for seedpods) is a different
numbering system !
Why ?
The numbering system explained above is used to identify specific clones
(my dark flowered clone of "species x", my Mexican "species z").
The outcome of the seedpod in question is variable, so the designation of
the seedpod number does not work since seedling A can be quite different
from seedling B.
In our laboratory a second numbering system is used, this time based on the
abbreviated genus in question (seedpods from unidentified species get "SP"
(= species) as abbreviation).
When a seedling from that batch is selected for the private collection,
then it is registered and the reference to the seedling batch is entered in
the record.
e.g.
Paphiopedilum crosses -> PAPH001, PAPH002
Stanhopea crosses -> STAN001, STAN002
(only 3 digits as we will not attempt to make more than 999 pollinations
within the same genus, so far so good)

Kenneth

dominance (this deals with one gene also) because in the F2 generation
there are not once again individuals the same as either parent. Another
Mendelian principle is termed independant assortment (this deals with
more than one gene). But the hybrids don't seem to fit this well either
because of intermediate characters, ...blah, blah, blah. Nevermind
terminology, this is not what you were asking for anyway. I do agree with
what you said above and have heard that most of the variation seen in the
Sarracenia hybrids appears in the F2 generation. Petiolaris Sean is
expected to soon be back online with his computer. Maybe he can tell us
more. He does have second and third generation petiolaris complex
hybrids.

Hi again CPers,
Yes, you are correct Joe, I did cross them. These two species produce a
fertile hybrid but will not cross with any other Drosera species. D.
burmannii and D. sessilifolia are of the only members of the generic
subsection Thelocalyx. Last year I got seed of a form of D. burmannii
from Robert Gibson in Australia which he calls Pillaga Red. This form
looked identical to the plant of D. sessilifolia Fernando sent me from
Brazil. Still, both species names are legitimate.
There is a funny story about the first burmannii/sessilifolia mixup. I
wrote an article titled Relating D. burmanni and D. sessilifolia in the
Oct. 1994 Flytrap News. The then president of the NSW Australia
newsletter Dennis Daley came up with a theory that D. burmannii had been
brought to S. America by Australian colonists. Fernando informed Mr.
Daley that D. sessilifolia had been discribed and reported widespread in
1824 previous to the New Australians. In defense of Mr. Daley's theory I
pointed out in personal correspondance to Fernando that D. burmannii
could have been spread to S. America by Early Viking Botanists circa 1100
A.D.:-) Moral of the story; --There seems to be a prevalent notion that
anything spread by birds is perceived as natural, while anything spread
by Man is unnatural. Here is the spinoff of that: If we could show that
D. burmannii was spread to S. America by Man, then we would all quickly
agree that the name D. sessilifolia should not be.

Subject: Re: Numbering, KK1386, etc.
Hi Kenneth - long time no hear!
I thought your explanation of accession numbering used at Akerne Irchids
was great; a timely piece following a lot of explanation showing exactly
how a numbering system is used within te world of orchids. This is
especially useful as I dobt any plant group can claim to give rise to
the complexities originating within orchid collecting and hybridising.
Some commnet from me on the system used, but not aimed at akerne Orchids
- it's aimed at those who wish to start numbering.
There are probably an infinite number of templates you can select for an
accession number. The simplest is a plain number sequence, 1,2,3,4,
etc. Next would be the same sequence but with a fixed length and zero
filled. An example of such a sequence of a length of 5 digits would be
00001, 00002, 00003, 00004, etc.. Beyond those two you can add anything
you like, but why would you. Well, without any exceptions that I know
of (repeat, that I know of), there are two reasons. The first is that
you are such an intrepid collector that you run out of numbers, i.e. in
a fixed length example such as te one above, you reach the end of
available numbers (e.g. 99999). To increase available numbers, you
would then start a new sequence that began with a new sequence number.
For ease of reading you might also add another character, such as a
slash or hyphen. Thus you could create 1-00001, 1-00002, 1-00003,
1-00004, etc, or something similar. Note that in the three sequences
I've shown, you cannot determine any information at all from the actual
content of the number. No part of the number has any meaning other than
to make the number unique allowing you to use it to referenece a single
plant specimen or goup of specimens that have the same origin and
represent the same plant type.
Therefore, the other reason to add additional data to any plain number sequence is to add information to
the sequence. Examples (taken from things i've seen) would be as follows:
AO-01000 where AO represents Akerne Orchids (so you could
replace with other "owner") date-01234 where the date can
represent when the plant joined the collection or
anything else you want it to collect
coll-01234 where "coll" is another number that represents a
filed trip loc-12345 where "loc" is another number that
represents where the plant is
physically located in the location
hybrid numbers such as AO-date-coll-loc-01000 where lots of
meaning is captured within
the accession number.
Now again, I emphasise, I am not criticising any existing method used to
number a collection, especally not that of the zoo (see earlier
discussion) or Akerne Orchids. However, the inclusion of any data
within the accession number (or within a Collector's Number) is
unnecesary and simply adds effort to that equired to maintain the
numbering system. It can make the numbers attractive but otherwise
serves no real purpose. Why? Well lets consider two alternatives in
how you keep records (and I can't think of more than two!). These are:
1. you keep paper records
2. you keep electronic records (word processed, spreadsheet, database, etc.)
I'll start with paper records. In paper records, the numbers can not be sorted on command into separate
groups. Each record stays where you write it forever. So the number can't be used as an aid to create
some sort of list. If you are keeping like numbers in separate parts of your paper system, since you have to
know which plant belongs in which list before you give it a number, you can add it to the correct list and
give it a plain number that is the next available in a plain number sequence. The extra meaning in the
numbr is unnecessary. The record pointed to by the number can give all the appropriate data such as
dates, collector's names and numbers, locations, etc, etc, etc. There is no data that you can add to the
number that can not be recorded in the record. No data added to the number should be ommitted from
the record pointed to. So why write it twice?!!!
As to electronic records, the same points all apply except one. In
electronic records, the accession number can be used to sort a list
automatically using the intelligence of the computer system. With plain
text documents created in a wod processoir (Lotus Notes, Microsft Word,
etc.) you could just argue that this was a benefit but only if using
pure text without tables. If using text in tabular form or if using
spreadsheets or a database system (e.g. Microsoft Access), hen once
again the additional information becomes repeated data entry and serves
no purpose. You can sort abased on columns or fields in all these
solutions so it is easy to record each piece of data separately, without
incorporating one piece of data (say a date) into another - such as the
Accession Number. You can then sort on one or multiple fields to create
the required lists - effectively sub-categories or sub-collections.
This does not, of course, get away from the charm of accession or
collector's numbers that comprise letters, numbers and maybe even
special characters (hyphens, slashes, asterisks, etc.). But I say
again, for those of you starting such a numbering system, there is no
need to introduce anything more complicated than a plain number sequence
where the next plant you number is simply given the next unused number
in the sequence.
On a separate note, regarding the central recording of accession numbers, this is not normal practice and
is as far aas I can see unmaintainable. Jan just answered this by saying he couldn't link his database to
plant identities where the plant had disappeared from cultivation. In addition, to do so would try to wor the
system backwards. The numbering system is generally employed to trace a plant's origins, assuming you
actually have the plant already. In such a case, if you recorded the number (and where yo got it from) and
if each person before you did the same, you can trace the plant back to it's origin without the aid of a
central database. Even if someone fails to record their details, you may be able to jump that person's data
gap by tracking the origins of other plants, if they have a collector's number (on;y or plants that originated
from a wild collection).
>But see those KK numbers, like KK1386? Those are the numbers that
>cactus collectors covet.
> What do these numbers mean?
It's not clear but the way the list is written one would expect these to be Collector's Numbers which are
very valuable (scientifically) as they point to a plant whose origin's can be traced back to a collection
made at a particular time, date and place in the wild, and indeed to a specific collector (which can
increase the trustworthynes of the collected material nad the collection data). Based on the other
database that identifes KK as being Karel Knize, of the Czech Republic, this increases the likely hoodthat
the number is a Collector's Number. It is not uncommon for collectors to preface their numbers with their
initials or some other acronym representing themselves (though this is not necessarily helpful as duplicate
acronyms can arise unless a central datbase records and controls them!).
Michael makes a good point. Just because you get (buy?) a plant with a number, it doesn't mean the
reference is correct!!! You have to know the supplier for one. Second, you really should try to identify the
plant to see if it matches what the numbers suggest. But don't worry. If you collect for fun and can't be
bothered with all that identification, you can just record the data. It will never reduce the value of your
plants but it can increase their value.
>10 could be Venus, 20 could be trumphet, 30 could be picture.
>A cross between trumphet and picture could be 250.
As I've said, you can do this sort of thing. But I advise all satarters, again, the more meaning you give to a
number, the more hard work you create for yourself.
Let me put it another way - WARNING, do not assign meaning to accession numbers or consituent parts
of them. Maintain a simple sequential number series.

Paul

Dear Paul,

Several different cases here:
> for example because the name already exists in that genus
Such things are called homonyms. If the plant is different (from
the plant that was first described with the same name) and if its
description was published together with the name, the ICRA
(registration authority) would inform the author that the name he
used is a homonym. Prior to registration, the ICRA would ask the
registrant to choose another name. Registration would be effected for
the new name, and the later homonym would be listed in the
International Register together with a note leading to the registered
new name. Creating homonyms can be avoided whatsoever by publishing
the description in CPN, because this is the Journal of the cp ICRA,
and its editors do check all submissions against the cp database
(which includes the International Register of cp cultivar names)
prior to publication.
> or because insufficient description is given to allow association of
> the name with some known appearance
Any text written by the describing author should *in the author's
opinion* distinguish the new cultivar from all cultivars described
before. The important point here is the author's opinion, if this is
satisfied (and if the description is *published*), the new name is
established (but not yet registered!). The cp ICRA requires
submission of the description *plus* a standard colour photograph of
the living plant, in order to be able to register the cultivar name.
Again, it is the *registrant's* responsibility to submit a picture
that shows all distinguishing features. The available data (author's
description, registrant's standard) are kept and published by the
ICRA, and the public is thus enabled to make decisions based on
qualified (UNCENSORED!) data. Although this procedure may seem
complicated or fallible, it is considered better than decisions based
on guesswork, insider information, or opinions. The important point
is that establishment or registration of a cultivar name do *not*
depend on the *quality* of description or standard but they do merely
depend on *publication* and *availability* to the ICRA (and
therefore, availability to the public).
> or because the description given in no way allows the cultivar to be
> distinguished from another previously described cultivar.
The same as above. The ICRA is not entitled to *make* such
judgements. It has to *allow* such judgements by publishing the
facts. Nothing else.
> Is the name ignored?
No. If published and submitted for registration properly (with
standard, v.s.), a cultivar name must and will be registered, so it
will appear in the International Register.
> Is it recorded as an equivalent of an invlaid name?
Only if the registrant does want this to be done or if the
nomenclatural Codes (ICBN and ICNCP) allow and require this, and
only if the rights of other registrants are not affected adversely .
> Is such a name barred from future use as it's use has been inappropriate?
A later homonym should not be used (because it is ambiguous). Names
falling into other categories mentioned above can be used once
they are established and registered.

Of course, it's almost impossible to assign each sample in cultivation

I have had an interesting (if somewhat frustrating) experience with
Pinguicula leaf cuttings. I have started these in both live Sphagnum moss
and in vermiculite, with equal success, but no success in peat-sand mixes.
Anyway, I have been noticing that once the cuttings get to a certain stage,
the older leaves start to go yellow and wither, and this withering seems to
catch up with the growing tip faster than the plant grows leaves. Is this
normal, or are the plants in need of something else?. This is more of a
problem in plants in sphagnum than those moved to a
vermiculite/perlite/grit/peat mix.
I have just started trying to fertilise them with a 1/5 strength low

them. However there seems to have been no improvement yet.

"Shedding light" may be the key phrase, there. How much light are the

Subject: Re: Trinidad CPs
Hi Michael
I've good news and bad news.
First, if you like Utrics then Trinidad's a great place to visit. The bad news is that getting to se any is
difficult if not near impossible.
The best book to use is Peter Taylor's monograph on Utricularia as it lists approximate (very approximate)
locations. In brief, there are 3 obvious areas to look in. The high mountains (look on any map) are home
to U. alpina. This is in cultivations so is hardly worth removing from habitat. To see it you have to find
literally the veryhighest mountain aeas and then walk. It's damned hard to find any, Trinidad is not the
best place to find it.
Second is Tar Lake (again, use a map). This is a natural lake of hot
tar that escapes from the Earth in Trinidad and, at it's other end, in
Venezuela. The tar is covered by water to form a hot lake that you can
walk in, standing on the tar. Nearby houses are built on higher tar and
gradually sink into it over the years - amusing to see. The lake is hme
to U. ********. OK, it's acommon Utric, but it's nice to see how it
lives.
Best of all is the Aripo Savannah. This is a large area of fairly
regular "fields" that look artificial or cultivated but are natural.
Each "field" is surrounded by a natural fence of scrub and trees. The
fields vary in height and, as a result, and all being at flood level,
the fields are therefore wet or flooded to some degree or another. You
need waders (rubber thigh length boots) to avoid getting wet or you
accept that you'll get wet and also offer your flesh to anything in the
water!!! Oh yes, there are also the anacondas, which live wild in Aripo
and are considered large enough to be dangerous even to adults, though I
personally doubt this is true - unless they're very hungry!!! :-)
The problem is that the Aripo Savannahs are a National Park and totally
protected. By totally, I mean that legally, you can not just walk
around inside the savannah. You need a permit. Of course, the
savannahs are huge, so one can imagine that walking in them without a
permit may be quite easy to do without being caught. But they are well
patrolled (men with cutlasses, or some call them machetes).
Alternatively, there is a small "office" along the edge of the savannah
where you can ask permission to enter. They may be in a good mood or
may just say no. Usually they say no as it avoids any need for
paperwork. If you can travel with any letters of introduction form
published botanists it might help. But it might not. I got in the
first time because I knew Peter taylor and had a letter from him as well
as being an ex-eacher from one of the most famous of all Caribbean
schools (in Barbados). They also let me in because they thought it was
hilarious that I was going to protect myself against any giant anaconda
by using my nice diver's knife (which they reckoned might tickle the
snake if i was really strong!). I think they wanted to see if I got
eaten! The second visit I made, they let me in because they had let me
in the first time!!!
If you do get in, something is always in flower. You can bet that
wherever you put a foot there will be a minimum of 3 different Utrics
squashed and maybe as many as 6 or 7 species. Overall, there are more
species than that but you'll need 2 or more wekeks to find them. Many,
and in my opinion the most interesting, are deep in the savannah in deep
ditches full of water - they are of course fixed aquatics. But you can
certainly see some exciting species where the savannnah is flat and wet.
U. hispida is worth looking out for as it's habitat preference seems to
be different in Trinidad to Brazil (I've discussed this with Fernando).
You'll find this speciesd in wet areas where most of the land is under
about 1 inch (2 cm) of water. The plants will be on the top of small
bumps of soil, each single clump growing next to a single clump of hairy
grass. No-one knows why the two plants are associatedn though i suppose
they both like the same conditions.
In other parts of Trinidad, esecially in deep water filled ditches,
there are other Utrics but finding them will take a long time. Sadly,
the removal of anything from Aripo is totally forbidden. However, there
is no real likelyhood of finding any new species there (it's been
thoroughly researched for years by Peter Taylor and many famous and less
famous Trinidadians) so why seed can't be collected I don't know.
Of all the islands in the Caribbean, Trinidad can live up to a reputation for having the least helpful
inhabitats who don't go out of their way to help tourists (Trinidad once found oil and thought it could
survive without tourism - it didn't, and the oil mostly ran dry - but the independence from tourism liners
on!!!). Be patient and friendly and keep your fingers crossed. If people say no, look sad, look as if you
might cry, and try another way to ask. Praise the uniqueness of the place and the way its an excellent
example of conservation that you've travelled miles to see. As long as you don't make someone angry (in
which case be very polite and leave), the more time you spend asking for help, the more likely they are to
think it will be quicker and easier to say yes than to say no!
Oh, I almost forgot. How unlike me. There are a couple of funny rosetty red things too. However, even
Fernando would find it hard to get excited about them!
(There used to be a wild population of Dionaea. It was planted by the tar lake on private property. But i
doubt it's still alive as the plant gets no rest period in Trinidad so will by now have become exhausted and
died out. They were an attempt at a commercial exercise.)
Hope this helps a little.

Subject: Sarracenia seed dispersal
Hey Folks,
Sarracenia seeds are hydrophobic. They can float and float. Put them in a
body of water and they'll go anywhere.
On the other hand, field researchers have noted that plants such as
S. oreophila can migrate uphill, and have suggested that the somewhat
stiff flower stalks may act as slings, throwing the seed as they get
tossed about in the wind.

I'm surprised this topic did not generate more interest!
Your observations certainly seem to confirm my thoughts on the subject
though as I mentioned in my posting there is probably some secondary
means of dispersal of seed between suitable habitat, unless a case could
be made for a far more extensive and interconnected bog system in the
eastern North America.
A useful means of observing migration of seedlings through populations
is to observe plants in sites where there is a predominance of one
species with single or very few plants of a second. Where these species
readily hybridise it is possible to see hybrid plants of second and
subsequent generations move in a radial pattern from the original
parent. I have seen this phenomenon at several locations in the south.
At one site the hybrid progeny could be seen clearly moving away from
the parent. The further away from the original parent the hybrid "moved"
the more like the predominant species it looked. The migration of the
seedlings also almost certainly followed a water course - the ground
sloped away from the parent plant in the same direction as the migration
was observed.
Your abstract on Sarracenia growing season dormancy was interesting and
recalled a previous conversation. Do you know a guy called Randy Zerr?
He lives at Fort Walton Beach in the Florida panhandle and has done a
lot of work in the Eglin Reserve. He has found plants of S. flava
growing in a semi-dormant state in the summer. The plant were growing in
well developed planted (not natural) pine forest and had plenty of non-
carnivorous phylodia leaves but no pitchers. Randy estimates the age of
the pine trees to be about fifteen years. The assumption is that
probably for the first five years the Sarracenia were able to grow more
or less normally before the trees grew tall enough to block out the
sunlight. Therefore the plants had probably been in this "dormant" state
for the remainder of the time until Randy had found the plants. He
removed a plant to see if it would revert to normal growth once given
sufficient light - it did.
I would not consider this state of growth to be dormant since the plants
were obviously still growing. I would consider however that the plants
were in a state of reduced growth - you could call it semi-dormancy. The
plants were not flowering and were not producing pitchers. They were
most likely surviving at a reduced growth rate from food reserves stored
in the rhizomes. No seedlings or juvenile plants were observed at the
site. It is an assumption, but a pretty good one, that the plants were
surviving in this reduced state until conditions improved.
I suspect that at least some Sarracenia species are able to make this
change in growth type as a means of survival when conditions
deteriorate. It is likely that this was originally a means of surviving
periods of drought and in fact I saw this sort of shut down in growth
last fall in the south where the area had been subject to very low
rainfall throughout the area last summer. Many areas of S. leucophylla
were observed with nothing but phylodia growth. At other areas plants
had produced fall pitchers but these were reduced in height. The most
interesting areas were plants that had apparently aborted all pitcher
growth in favour of seed production. Plants were seen with no leaf
growth other than phylodia but with mature seed pods. The assumption is
that the plant's reaction to drought differs according to what stage of
growth the drought occurs. If it occurs before seed has set the flowers
and pitchers abort - in some instances phylodia are produced but this is
not always the case. If seed production has begun then all growth is
aborted in favour of seed production. The reasons are obvious - the best
chance of survival is by dormant seed, which may lie in the ground for a
number of years waiting for favourable conditions to return. Failing
that the plants will attempt to survive in a shut down 'semi-dormant'
state.
Do you know of any work that has been carried out on the ancient
distribution patterns of Sarracenia and its related genera? One thing
that has puzzled me for some time now is how the apparently related
genera of Sarracenia, Heliamphora and Darlingtonia became so widely
dispersed from one another? There are apparently impenetrable barriers
separating the populations - mountains, deserts and sea! Of course these
barriers may be geologically recent events but even so the distance
between these genera is impressive on its own. Add to that the fact that
the tepuis are very ancient pieces of uplifted sandstone and have their
origins in Africa.
One idea is that the genera, or some predecessor may have existed in
central America at the time of the last ice age. During the ice ages the
sea level was considerably reduced perhaps allowing boggy habitat to
form all along the gulf coast. Also the climate may have been both
cooler and wetter due to the relative proximity of the ice cap. Do you
know how Sarracenia and the other genera fit into the geological time
scale?
Our society committee will be meeting in March, by which time the sub-
committee will hopefully have come to a decision about your funding
application. If there are any developments I'll let you know,
unofficially or officially.

Ever run across one of those giant clumps of S. minor in the wild. If you
get down on your hands and knees and search out the flower stalks, you'll
find that they hang away from the plant at about a 30 degree angle. That's
probably an evoluntionary advantage brought about by a flower stalk that is
decidedly shorter than the other upright Sarracenia, which produce tall,
straight inflorecences. Hanging away from the plant allows the seed to fall
on bare ground where it has a better chance of surviving. The upright
pitchers, on the other hand, can still produce large clumps but probably
have the advantage of a flower stalk being blown down by strong winds and
falling far from the plants rhizome, again allowing seedlings space to grow.
I've never seen clumps of S. psittacina. I think what's happening there is
that S. psittacina prefer habitat that regularly is flooded, for instance,
ditches, and therefore seed is much more likely to be moved around by water.

Subject: D.sessilifolia/flora ; collection numbers
To all,
I'm really enjoying this thread and wanted to say that I'm all for
adding numbers, since I already use a numbering system: my
herbarium collection numbers. I always collect herbarium and
include all sorts of info, like collection number, habitat info,
plant colors, and even GPS data. I guess if we're all in
agreement (or at least most of us), all we have to do now is
convince seed banks worldwide to take these numbers into
consideration. In my case, I guess Rivadavia followed by the
number would be correct. Or simply my initials would be better
maybe, like that Czech cactus guy (KK).
To Greg, Miguel, Joe, and everyone,
>Sorry Miguel and Joe, you said D. sessilifolia but I was asking about

>that's for sure. I think I'd better leave it until I get a web page up and

AAARRGH! Let me put an end to this before it goes any further!
This is one of those confusions which just goes on and on and
makes me want to forget this whole numbering system story,
especially because I'm always writing about it here and yet it
keeps coming back to haunt me, like the Friday the 13th movies!!
There is NO SUCH THING as D.sessiliFLORA. This is a misspelling
of D.sessiliFOLIA. Furthermore, seeds being traded around as "
D.sessiliFLORA" and a few D.sessiliFOLIA are NOT the real
D.sessiliFOLIA. THAT is why your plant does not look like
D.burmannii and is not annual, Greg. As Paul would say, it's one
of those red rosetted thingies. African by the way...
While on the subject, I'd forgotten about that ACPS D.sessilifolia
story Ivan, hahaha! I don't doubt that D.sessilifolia could have
been brought by man, but if this was true I would say it happened
a few thousand years ago AT LEAST. After all, it occurs from
central Brazil all the way to N Venezuela. It's the most
widespread of all S.American Drosera (well, second maybe to
D.communis).
I've no doubt however that it did come from Asia and not
vice-versa, since it seems to be surprisingly unvariable for such
a widespread plant. D.burmannii on the other hand is far more
variable (Ivan, I'd love to see pics of this D.burmannii you said
Rob collected and which looks like D.sessilifolia!), which to me
suggests that it has had a longer speciation time and therefore
has been around there longer. I use the same thinking to assume
that D.brevifolia came to Brazil from the N rather than
vice-versa. Usually larger genetic variability indicates the
place or origin. Look at the recent genetic studies with
H.sapiens...

This may be true *within* S America, but is definitely not the case
from a global point of view. In contrast to the two species you
mentioned, there are three others that extend to N America, viz. _D.
intermedia_, _capillaris_, and _brevifolia_. Of these, the first also
occurs in the Old World, and therefore, this is the unchallenged,
most widespread of all S American _Drosera_.
While I agree that _D. sessilifolia_ might have come from the East
(of Gondwana), humans do not need to have been involved (BTW: humans
did not exist when Gondwana was *one* continent!). The most striking
feature in the recent distribution of Thelocalyx is its apparent
lack in Africa, if it is assumed to be an old Gonwanan element (it
is quite certainly an old element in the genus: "primitive" pollen
type, 5 carpels). I have written "apparent" (for those who did not
notice it), because I think Planchon (1848) mentions a specimen of
_D. burmannii_ from Sierra Leone (W Africa)! This specimen (an
Afzelius collection) is not mentioned by Diels or Hamet nor by any
subsequent author. I have not seen the specimen (it might be at P or
K), so I do not really know what it is.
Of course it could be assumed that the plant came to Sierra Leone
by ship together with goods from Asia. But where would you expect S
American elements to have survived (from Gondwanan times) in Africa?
Right in Upper Guinea (remember the recent discovery of the American
_Utricularia juncea_ in Ivory Coast)! So perhaps the Afzelius
specimen is not _D. burmannii_ but rather _D. sessilifolia_. But the
two may be the same, anyway. In any event, the African gap would be
much narrower, and it could be explained by the droughts that have
eliminated much of Africa's original flora.
It would perhaps be interesting (for our British or French
colleagues) to look for the Afzelius specimen and maybe (for those
who visit the region) to look for further specimens of strange
rosetted things in W Africa.

Steve and others,
Thanks for recommending that people donate seed to our Endangered Plant
Propagation Center. We are currently developing a formal system for
accepting seed donations, but are glad to accept any contributions of
seed either for our efforts, or on behalf of the Millennium Seed Bank,
now. When our seed donation procedure is finalized I will put more

We currently have seed for about 1,200 species and varieties of CP which
we are starting at our location in Watkinsville, Georgia. There is not
much to see yet, as we are just planting most of the seeds now, so we
only have some small seedlings started so far. This said, anyone
passing through the area is welcome to visit. Just give us a call, or
e-mail, a few days ahead. The phone number here is (706) 769-1000.
Also, our address is:

It probably depends much on the plant. Some plants do not have a
dormancy requirement and will grow all year round.
Generally though, for most plants that have a dormancy its just a
question of letting the plant adjust its own growth pattern. This
usually takes about a year. The exceptions are plants that enter a true
dormancy such as tuberous and pygmy Drosera where more care is needed to
allow the plants to adjust to the seasons.

Several things spring to mind. You could be keeping the cuttings too
wet, too humid, too warm or you could be giving them too much light.
What you report is certainly not normal - I have never experienced it
anyway.
There is one other possibility. You could have a fungal pathogen - not
necessarily the usual botrytis. Have you experienced any similar
problems with rotting in your plants? A few growers have had problems of
this sort. Usually the problem starts with a few of the leaves starting
to rot and then very rapidly (often overnight) the entire plant
succumbs.
If you think this might be the problem you could try a fungicide though
it is likely that simply increasing ventilation and decreasing humidity
could be equally successful.

Its just a small point but seeds of all species except those listed

As far as I know there are also no phytosanitary restrictions regarding

Hi Phil:
I am answering a number of questions you proposed below and also want to
alert ICPS members again about the preserve we are building in southern
Virginia. We have applied to the UK CP Society for a grant to help in
our acquisition of a pitcher plant preserve in southern Virginia and
solicit the rest of the ICPS membership in that effort. Our
organization, Meadowview Biological Research Station, is an official IRS
501(c)(3) organization to which you can now donate tax deductible
contributions. In brief, our goal is to capture the entire native
Virginia longleaf pine (4432 trees) and yellow pitcher genome on one
preserve, along with about a dozen other native rare associate species.
The future preserve encompasses 100 acres of gently rolling terrain and
sphagnous seepage wetlands within the heart of the longleaf pine and
yellow pitcher plant range in Virginia. We have worked with the
landowner over the past four years and have successfully reintroduced
one population of S. flava and have very successful test plantings with
longleaf pine. Sarracenia flava will be planted in separate seeps based
on separate sites to preserve local identity to the best extent possible
(one population allowed to bloom per year). The preserve will be managed
with fire and we have the possibility of eventually significantly
expanding the landholding. Please note that two of the native Virginia
S. flava populations we have studied over the years have done extinct
due to flooding or habitat degradation. We are now the sole repositorty
for these genomes and these plants are maintained in above ground beds.
We would like to return them to the wild in a secure area and the
preserve offers that opportunity.
Purchase price is the assessed value of $113,000. We have already
received a cash donation by Keith Underwood and Associate, of Annapolis,
Maryland for $750.00 and have set up the savings account for land
putchase. If you wish to make a donation and have it dedicated to the
preserve please indicate this on our sponsorship form at our web site at

Yes, but I don't like the term dormancy. Since they still produce leaves
(pyllodia) and weak pitchers they are actively growing and not dormant.
Sarracenia typically responds to reduced light levels in this fashion.

I agree. Waiting for some kind of disturbance, such as fire. Although
this can get a lot more complicated. In natural systems, even in the
absence of frequent fire, you can get small natural gaps with full sun
surrounded by much more shaded plants.

There is speculation by Fred and Roberta Case in their S. rubra papers.
Also check early Wherry work. There was also a paper a few years back on
Heliamphora, Darlingtonia, and Sarracenia spred from progenitors in

It reminded me of something I read in "The Wollemi Pine" (author James

central Australia.
Can anyone point me to an info source on CP evolution, palaeontology?? For
example, I'm curious about how Nepenthes managed to grow in
Madagascar. Also, I'd like to know if they ever grew in Antarctica.
For those with a general interest in botany, I would recommend looking at
the Wollemi Pine site at
http://www.rbgsyd.nsw.gov.au/html/Wollemi.html Initially there were only
two stands of trees containing 29 adult plants, all of which are
genetically identical, however a third stand has been found. (Happily,
those involved don't have to worry too much about collection numbers).

I suspect you are right in the case of all CP species, but this not
universally true. Potato or grape seed is totally prohibited, for
instance, and various other crops and their wild relatives need
certification. Kew, as a registered quarantine centre, has the power
to issue a 'letter of authority' for the import of restricted material.
But the whole issue is complicated beyond belief! The form we

Hi Fernando and all,
Sounds like you are suggesting that D. burmannii only made the trip once
fairly recently, and that explains less diversity in S. America; very
reasonable. I was thinking before that D. sessilifolia has been in S.
America a very long time, but has been going back and forth over time and
this is why both D. burmannii and D. sessilifolia are genetically
compatible. Anyway, what course do you figure the plant travelled?
Through Asia and across the Bering Straights to N. American and then
south? Hey, I think I just figured it out! How about the species made the
trip once during a narrow window of time 12, 000 years ago when the land
bridge was open?
That would be good to see if you could pick out any difference between
that particular form of D. burmanni and D. sessilifolia. I remember how
when you looked at my collection you instantly distinguished them and
even my hybrid. This form from the Pilliga Scrub NSW I certainly could
not tell from D. sessilifolia. It even had the pinkish tinted flower
which is more typical in sessilifolia. I only have one photo print of a
single plant and have no scanner. I'm sure Robert could scan some for
you.

Well, since Fernando mentions that it is a South African Drosera, some
idea of what it could be comes to mind. Besides for one of the many flat
rosetted species from S. A., it could be a hybrid. The best way to tell is
to post your photos, but even then some photos don't reveal the details
needed for ID...
Also, your plant may not be named yet. Some species are traded, but are

December, even though most of my other neotropical Pings had long since

which time (and at ca. 15 cm in diameter) it began to show rapid senescence
of most of the basal leaves. I stopped watering the plant, and it appears to
be in a state of suspended animation - the growing point and the youngest

Kevin, Yes, there were giant venus flytraps but the size was later found
to be due to environment and cultivation as opposed to genetics :-).
Before you get excited I'll warn you that I work in the not very cp
related world of animal developmental biology so I am nowhere near an
expert in evolutionary biology. I did a quick search on Bioabstracts
and managed to pull up the following paper: Truswell, E M. & Marchant, N
G. (1986) Early Tertiary Pollen of Probable Droseracean Affinity from
Central Australia. Special Papers in Palaeontology. 35:161-176. I
don't have access to this Journal so I can't tell you too much about the
findings. The abstract is as follows: "Fischeripollis halensis sp.
nov. is described from the Ulgnamba Lignite in the Hale River Basin,
northeast of Alice Springs, central Australia. This unit, on the
evidence of a diverse palynomorph assemblage, with some constraints
provided by palaeomagnetic dating of deep-weathering profiles, is
probably of Middle to Late Eocene age. Abundant rainforest taxa in the
pollen spectrum suggest high, uniformly distributed rainfall. The
similarity of F. halensis, which occurs either in single grains or in
tetrads, to pollen of extant Droseraceae is evident in the
proximo-equatorial ring of large apertures, and in the grain wall, which
bears processes in two distinct size classes. The strongest resemblance
is to pollen of extant Dionaea, the Venus Fly Trap, which occurs today
only in the south-eastern United States. The presence of pores which
penetrate directly into the main body of the grain, rather than into a
system of radiating channels on the proximal face, suggests relationship
with the Dionaea lineage rathe I don't know how these results were taken
within the appropriate scientific community. Given that sex and
development tend to be slower to evolve compaired to other morphological
and physiological processes and Australia already has a high degree of
Droseraceae representation, including the closely related Aldrovanda, it
may not be unthinkable that a prehistoric flytrap existed in Australia.
If it was indeed ancestral it would imply Dionaea (or its ancestors) had
a distribution over a number of (future) continents. Conversely, the
article may simply imply that the species of Fischeripollis in question
had some N.American ancestry. I'm not familiar with this plant so I
wouldn't attempt to say either way. Hope this helps. Andrew

Subject: flytrap fossils
Dear Kevin & Andrew,
As a little appetizer for my prospective cp evolution paper (to
be submitted to CPN), I paste here what I have summarized on
Droseraceae fossils:
"Fossil pollen has been attributed to several genera of Droseraceae.
A single record from central European Mid Miocene (called
Fischeripollis) has been assigned to Dionaea (Krutzsch, 1970). An
interesting series of fossil seeds and even leaves (perhaps traps, if
the interpretation is correct) could be established since Senonian
for Aldrovanda (Degreef, 1997, Schlauer, 1997a), occurring through
large parts of temperate Eurasia (which used to have a warmer climate
than nowadays, and which lacks Aldrovanda in great parts now) with
several different and now extinct species and genera (Saxonipollis).
This is in very good consonance with the widely scattered
distribution of the recent Aldrovanda vesiculosa throughout the old
world, resulting from glacial fragmentation of a formerly continuous
range. Droseraceae pollen (Fischeripollis) is represented in the
Early Tertiary strata of central Australia (Truswell & Marchant,
1986). Mid Palaeocene pollen specimens from Assam (Cherra formation,
Droseridites parvus, Sah & Dutta, 1974) are of uncertain attribution
but could also belong to Nepenthes (N. khasiana being at least
geographically a very close recent species, v.i.). Drosera pollen has
been recorded since Lower Miocene from New Zealand (Mildenhall,
1980). Miocene pollen (as Droserapollis and Droserapites) of somewhat
uncertain droseracean affinity has been found in Taiwan (Huang,
1978). Several finds of Tertiary pollen (since Mid Miocene) from
Europe have been assigned to either Drosera (Droserapollis) or
Nepenthes (Droseridites, Krutzsch, 1985). However, there is little
probability the recent species of Drosera existed in Europe before
Pliocene (v.i.). Probably, the earlier fossils may be attributed to
now extinct lines of Droseraceae or even other families. Anyway, the
fossil record of Droseraceae pollen is the richest of any carnivorous
plant family, and it testifies a wide distribution at least of the
progenitors of Aldrovanda since Late Cretaceous. "
And on the question of Antarctic _Nepenthes_:
"Possibly of evolutionary significance is the fact that pollen
originally assigned to Droseraceae (Droseridites) from the Kerguelen
islands has been tentatively transferred to Nepenthes more recently
(Krutzsch, 1985). In this context Droseridites parvus from the Mid
Palaeocene of Assam (Sah & Dutta, 1974) should be considered as
possible Nepenthes pollen. Fossil pollen assigned to Nepenthes has
been discovered in the Mid Miocene of north Borneo (Anderson & Muller,
1975), and its presence here (a centre of recent diversity, cf.
Schlauer, 2000) is not surprising. But the assignment of European
Tertiary pollen to the same genus (Krutzsch, 1985) is at least as
puzzling as the dubious Triphyophyllum seed from Siberia (v.i.,
recalling to some extent a similar discrepancy between fossil record
and present distribution in Dipterocarpaceae and Clusiaceae)."

Hi Kevin and all,
To find such information you would have to look long and hard through
journals. From time to time we do here discuss the subject. Last year
before you joined was talk about an interesting one. A much televised
discovery of a 20, 000 year old frozen wooly mammoth in Siberia was made
a couple of years ago. Some scientists had the idea to clone this mammoth
to resurrect the species. One of us :-) had a more feasible idea of
locating frozen seed preserved in permafrost bogs to possibly bring back
extinct CP. This is not really so farfetched, since seed of a few other
plant species have in fact been found which were frozen for thousands of
years, and these when planted sprouted. Most of us listees felt that
nothing really unusual as far as unknown ice age CP species could be
found in the arctic region, but Jan Schlauer suggested the best place to
look might be Antarctica.
Here is an update on the Jarkov Mammoth. On the televised show titled
Raising the Mammoth on the Discovery Channel, apparently living plant
material was found beneath the frozen mammoth. I saw the program and
these too plants looked like some sort of sedge and the other maybe
Selaginella. They certainly looked green and alive to me. Coming this
March 12, again on the Discovery Channel, will be a program titled Land
of the Mammoth. I'm hoping that the plant material found will be more
discussed. I don't really expect Drosera, Pings, or Utrics, but this
presents interesting food for thought.

that the vines can bend and crack, but they rarely break. Climbing vines are
somewhat elastic to allow for movement of the supporting vegetation. You do
not mention the species or hybird, but some plants like N. alata can produce
great numbers of traps of considerable weight, but of modest size and with
rather flexible stems. Others like N. rafflesiana have much stiffer stems and
can crack more easily.
Plants allowed to hang as you describe will often produce basal shoots near
or below the soil level and then as the hanging stems age the plant may kill
the hanging portion off (recycling nutrients) and produce larger new growth,
eventually repeating the process again and again. When you see basals form
and develop five to seven good leaves, you can always make cuttings of the
hanging stems.
The climbing stem of most species will still often produce the coiling
tendril, and intermediate and upper pitcher forms even though the plant is
not actually climbing. In some aroids like philodendrons, climbing (actually
contact with a vertical surface) will produce upper leaf forms but I don't
believe this is necessary with Nepenthes.

New idea! Thanks for all the personal replies/thoughts. I've come to the
next stage. I couldn't find a photo of my D. aliciae to put on my album but
I will soon. I think that this sessiliflora plant I have could be a D.
aliciae, purhaps the yellow-green leaf form? The other one (the real one)
would be the green leaf form.
I saw these two names in the CP total listing. Is this true?

P. gigantea is a close relative of P. agnata and like this species the
plant does not form a non-carnivorous "dormant" state but does have a
period of reduced growth and rosette size. So yes, this does sound like
a normal growth patter for this species.
In most Mexican Pinguicula species the term dormancy is mis-applied
anyway since most species do not enter a true dormant state. Rather they
enter a xerophytic state forming a tight rosette of non-carnivorous
leaves. While in this state the plants continue to grow albeit at a very
reduced rate. A few species produce a very tight rosette of leaves
completely buried underground - very much like a bulb and may be
considered to have a dormant state.
Many species produce hairs on the surface of the xerophytic leaves the
purpose of which is to trap moisture from early morning mists -
virtually the only moisture the plants get at this season.

Hi CPers!
I'm getting into composting household waste and was wondering whether anyone has
had any problems with specific species of worms when feeding them to your plants.
I've fed many sarr.'s the local species of earth worms here in Manitoba, Canada
with no problems (they quite like them), but I was wondering if certain other

while being digested. Any advice or experience to share?

Subject: RE: CPalaeontology and D. sessili(aliciae)/ burmannii and their origins
To all,
About ancient CPs and their fossils, there was a very good series of
articles in CPN a few years back by John Degreef.
As for D.sessili(aliciae)...
> Well, since Fernando mentions that it is a South African Drosera, some
idea of what it could be comes to mind. Besides for one of the many flat
rosetted species from S. A., it could be a hybrid. The best way to tell is
to post your photos, but even then some photos don't reveal the details
needed for ID...
Also, your plant may not be named yet. Some species are traded, but are
not yet officially named.
The taxonomy of "red rosetted thingies" in Africa is still quite
confusing. Pay me a few years of botanizing in southern Africa and then I'll
tell you what it is... :):):)
>Sounds like you are suggesting that D. burmannii only made the trip once
fairly recently, and that explains less diversity in S. America; very
reasonable. I was thinking before that D. sessilifolia has been in S.
America a very long time, but has been going back and forth over time and
this is why both D. burmannii and D. sessilifolia are genetically
compatible.
I think it's much more likely that it made the trip only once, than
that it went back and forth several times (can you imagine D.anglica jumping
to Hawaii and back??). And if it was going back and forth over such a large
distance, you'd imagine it would be doing at least the same thing in
Australia and Asia, and thus the populations there would be morphologically
more uniform as well. As far as I know, D.burmannii in Asia are rather
uniform, suggesting that they also originated from Australia, where all the
variability seems to occur. The populations have to be more or less isolated
reproductively over long periods of time for diversity to occur. If they
were jumping back and forth often, they would be exchanging DNA, making the
populations overall more uniform. Isolation causes diversity, and eventually
speciation. We know they are not reproductively isolated, since the various
forms of D.burmannii and D.sessilifolia do seem to hybridize, so it can only
be assumed that their isolation is geographic. And probably recent, since
they have not yet become reproductively isolated.
>Anyway, what course do you figure the plant travelled?
Through Asia and across the Bering Straights to N. American and then
south? Hey, I think I just figured it out! How about the species made the
trip once during a narrow window of time 12, 000 years ago when the land
bridge was open?
Then why is it not present further N? Surely there are decent
conditions for it in Central America and southern N.America. I believe
instead that D.sessilifolia must have originated from a plant which hitched
a ride with a bird or wind over the Pacific or maybe through Africa (though
if it's present anywhere in Africa is still a mystery). Remember the seeds
of these plants are very tiny. Furthermore, during the last ice age, most of
Brazil was covered in savanas, while the rainforests were reduced to a few
pockets. Savanas are the perfect habitat for D.sessilifolia, suggesting why
it's so widespread nowadays. Once the ice age was through, rainforests seem
to have isolated D.sessilifolia N and S of the Amazon.
A single and recent colonizing event would help explain the
uniformity of D.sessilifolia, having originated from a small genetic stock.
Just look at the N.Hemisphere species like D.anglica and D.rotundifolia, how
widespread and uniform they are. These are believed to have spread widely at
the end of the last ice age, only a few thousand years ago. if I remember
well. That's why there is not much diversity... yet. A few thousand years is
apparently not enough for them to diversify into new species or even
varieties, but given time...
If there really is a D.burmannii form which is very similar or
identical to D.sessilifolia, it could be an indication of where the
D.sessilifolia stock came from. The good news is that the solution to this
puzzle is within our reach, we have the technology to solve it! The genetic
tools are there to test this!! If anybody is looking for a good project for
a master or PhD thesis involving CP genetics and evolution, this is it. All
you'd have to do is find one or more very variable genes to sequence or try
some other genetic fingerprinting like AFLP or RAPD. The resulting
phylogenetic tree would indicate which Australian (or Asian?) population was
closest to D.sessilifolia. The more populations sampled, the better. It
would even be possible to identify which are the most ancient branches in
this group, i.e. the most "primitive" burmannii/ sessilifolia. It would be
interesting to see on this family tree if D.sessilifolia represents an old
branch inserted below all the present branches of D.burmannii, showing they
had a common origin, but not exactly where or when... OR, if the
D.sessilifolia branch is positioned in the middle of the D.burmannii
branches, showing it originated from a branch of the tree still represented
by living populations, with "older" and "younger" inserted above and below
it. The latter would be my guess. Or else we'd expect to see the same
variability with D.sessilifolia in S.America as we see with D.burmannii in
Australia. Unless D.sessilifolia suffered a genetic bottleneck at some time
recently, nearly going extinct, but then later recovering from the few
remaining populations.
I'm sure it would be really easy to obtain D.burmannii specimens
from several different sites through our numerous CPers in Australia. I'm
also sure someone in Asia could obtain at least one form from there too. And
I'll be certainly willing to send a few specimens of D.sessilifolia from
different locations too. All you need are dried leaves and often hebarium
specimens are sufficient. Volunteers????
> That would be good to see if you could pick out any difference between
that particular form of D. burmanni and D. sessilifolia. I remember how
when you looked at my collection you instantly distinguished them and
even my hybrid. This form from the Pilliga Scrub NSW I certainly could
not tell from D. sessilifolia. It even had the pinkish tinted flower
which is more typical in sessilifolia. I only have one photo print of a
single plant and have no scanner. I'm sure Robert could scan some for
you.
I'll ask him.

And who says they spread over Gondwana? D.anglica sure didn't need a
land bridge to reach Hawaii. And how many million years ago are we talking
about, when they were all still connected? Surely if D.sessilifolia had been
here so long we'd see more variability, considering how widespread it is,
just as we see variability within D.burmannii in Australia. My gues is that
they jumped over oceans much more recently.

It might be an old Gondwanan element, but might not have left
descendents elsewhere than in Australia, until a recent spread to Asia and
S.America. A similar thing is seen with D.indica, which is widespread from
Australia to Africa, yet most of the diversity seems to be within Australia.
Herbarium I saw from Africa all seemed to represent a single form, very
similar to plants I saw in Goa, India. In Asia one finds white and pink-fld
forms, but not orange fls, or maroon plants, or such variation in plant
size/robustness, or even those with the red cobra-like stamens Allen
discovered in N Australia (and which I believe he'll probably separate as
new species/varieties in the future). Again I think this suggests an
Australian origin with recent spread elsewhere. And like D.sessilifolia/
burmannii, D.indica is mostly annual, which is probably an advantage for any
new coloniser.

No doubt!!! It would be great if one of the European CPers could go
spend a day at Kew or Paris trying to uncover these African specimens and
phtographing it for all of us. Of course there is always the problem of
herbarium curator-bureaucrats who often won't let you in if you're not some
famous botanist with good connections, when herbaria should be treated like
any other library, open to anyone who wishes to study its archives. I never
had too much problem, including during my brief visits to both Kew and Paris
several years back (before I knew about these Afzelius specimens), since I
wrote beforehand and had contacts there. And I guess because it would be
more difficult to say "NO" to someone coming from another continent, even
when your contact is not there (which is often the case). So if someone does
take up the idea to try and uncover these Afzelius specimens, be sure to try
and contact the curators at these institutions first. Furthermore, these
places are often "temporarily closed for visitation" for one reason or
another (usually reform) -- another reason to inform yourself before
appearing at the door.

Before this becomes blown out of proportion accidentally: it's a
joke, it's NOT real. These aussies came to S.America AFTER D.sessilifolia
was discovered. OK????

No universal numbering system is necessary. Everyone could make his
own, using his/her name/initials plus a number. For example I could label my
seeds:
_Drosera graminifolia_ Diamantina, Minas Gerais state, Rivadavia 1013
_Genlisea uncinata_ Catoles, Bahia state, Rivadavia 908
_Utricularia campbelliana_, Pico da Neblina, Amazonas state, Rivadavia et

The numbers would correspond (they're ficticious in this case) to my
herbarium specimens, which are all deposited here at the University of Sao

then just the number itself and collector would be sufficient to identify

In August I was in Florida with Bob McMorris and one of the
wonderful Sarracenia sites we visited was full of huge S.leucophylla with
extra wide "mouths". Next to these was a shady area full of S.leuco growing
under trees (natural, not planted). There were only phyllodia, thousands of
them all over. One or two sickly pitchers maybe. Call it what you want,
semi-dormancy or whatever, but they were "existing" if you don't want to
call that normal survival. I've see that with other CPs here in Brazil,
where they were growing in less than optimal conditions and were apparently
only hanging on, growing really ugly, but nonetheless surviving. So how long
Sarracenia can grow as phyllodia only I guess depends on how much nutrition
it can get from the soil to supplement photosynthesis. Maybe in shadier
conditions such as the ones above, maybe the extra organic matter from the
dead tree leaves and the possibly drier (less acidic?) soil permit the
phyllodia-state plants to absorb more nutrients through their roots than
plants growing in the more open, boggier (more acidic?) areas.

Nothing unusual about this, especially if you consider how many
millions of years ago these 3 genera had a common ancestor. Surely lots has
happened since, climate-wise at least. Maybe they originated in S.America,
maybe in N, or maybe even outside the Americas but left no living relatives
elsewhere. Just look at Aldrovanda and Dionaea. One occurs in the new world
and the other in the old world. Where did they originate, where was their
common ancestor? The related fossil pollen of Fischeripollis halensis is
from Australia. Who knows?! One could go on and on speculating about this,
but there is certainly nothing unusual about the geographic isolation of the
3 Sarraceniaceae genera, especially if you consider that there are SPECIES
which are more geographically isolated, like U.gibba, which is widespread
throughout the tropics, or D.rotundifolia which is widespread in the N
Hemisphere, or N.mirabilis which seems to like island hopping. If a species
can make it across oceans and continents, than certainly genera can
eventually be separated by time and evolution across the same barriers.

when they have glads to attract them? I'm getting fed up with scale. Those
bastardly argentine ants constantly cover one species of my nepenthes with
scale (samia says anamensis others say mirabilis). I dont have time to swap

also what are people's successes/failures with using pure perlite? I've been
considering making a switch to pure perlite with a fine layer of peat or

grow nepenthes? I was growing tired of them rotting in the pot with the
peat.
i was also wondering if perlite may be my solution to the ants as well. See
they seem to enjoy nesting in the pot once they realize the plant feeds
them. Will they or will they not nest in perlite?

Mix one part borax with one part icing sugar, when you want to use this, mix with a little water to form a cream. The ants will take this back to their nest and it will destroy it completely, with no harm to anything else.
I would just like to mention that in the UK, we are not allowed to use a chemical in the garden unless it is approved, but these ingredients are used in an ant destroyer that you can buy, I think that is unlikely that the police will turn up at your house!

Hi all
Now that I have that photo page going I can add a photo of the Pilliga Red
form for those who wish to see it, unless someone is able to produce one in
the next 5 days. Unfortunately I have just had printed a roll of film (no
digital camera) so will have to take the photos and have them printed before
adding them to the album. There is two D. burmanni photos on there from
other locations if anyone is interested.
I did add a photo of D. pygmaea with SEVEN petals!!! today. This was the
only flower seen with more than four petals, on recent field trips around
Sydney. Let me know what you think.

Subject: D. linearis
Hi,
I have germinated D. linearis this spring more or less successfully.
In autumn
1999 I obtained a few seeds (thank you again!). Half of the seeds I
sowed onto a mixture of 50/50 peat/(quarz)sand, the other half onto a
1cm layer of sphagnum knowing that this is not the natural medium.
Leaving the pots outside they were frozen down to -15C several times.
In spring 2000 some seedlings germinated and made clearly visible
winterbuds in autumn 2000 though their growth rate was much behind the
other three European Droseras in my outdoor bog. I think about
repotting them this spring.
Any comments for a better growth medium?

a hard plastic covering for my greenhouse I am building. What I have

because we all have to keep some kind of look that doesn't upset our

My question is : How important is 'harmful' UV to CPs? (The wording on the
package is calling them harmful in respect to humans, not plants)
One type of plastic omits them almost 100% while the other says it is good
for UV protectioon. I do not want to deny my cps any type of light since
this will be outside.
Does anyone use this stuff on their houses? What is sheet plastic made of?
Does it omit UV?
More that one question I know,

Hi Phil,
my plants germinated on pure peat.
D. Schnell reports on his book that in cultivation they can be grown on pure
peat or on acid peat/sand mix.
I found it is true and after a few years, having started from seed, I
succeeded in having one flowering plant last year.
Schnell reports it can grow in shallow water if it is not acid: in fact I
had my best plant growing outdoors on pure peat and when last spring I
watered it too much and the water level stayed high for several days the
plant rotted. It grew in full sun together with D. anglica, D. rotundifolia,
D. intermedia and D. x obovata, none of which suffered from the high water
level; so I supposed the acidity was the cause.
It seems however it is not a very difficult plant to grow: slightly more
difficult than D. anglica, but very far from D. arcturi and D. stenopetala!

Subject: BUGS!
Happy New Year(?) everyone,
I know this topic has been covered a thousand times, but I just spent my
Sunday unpotting and blasting with water a variety of succulents invaded by
Mealy bugs. What really works? I've been using alcohol swabs...I suspect the
reason things got this bad. I want to avoid pesticides if at all possible,
so as not to release even more half-life garbage into the world. I am
weighing just throwing out plants and helping to keep the nursery business
going, but losing some of these would be a shame...a couple of older
Ariocarpus among them. I plan to keep these bare root, check bi-weekly, and
blast with water weekly. I guess my questions are as follows;
Will a watered down alcohol spray covering the whole plant help? Will it
damage the plant? Is inhaling it just as bad as pesticide anyway?
Dish soap? Insecticidal soap? Do either work if you miss a single square
centimeter of surface area?
What about predatorial bugs? Are they practical pricewise? Available? How
often do they need to be reapplied? Can they be released indoors without
them turning up in my bed and shorts?
Where on earth do they come from?! I have heard Africa to the Caribbean and
up into the Southern US. Are they naturalized to the Midwest of North
America...Do I reinfect every summer when I place my plants outside? Maybe
if we knew where they were native to, we could combat them more easily.
Anyway, any ideas are appreciated,

Hi, Phil!
Back in the 1970's, I was a "guru" of Ontario CPs. Adrian Slack
(see the acknowledgement for JIM KOROLAS) even got my input on S.
purpurea purpurea and D. linearis.
As to growing D. linearis (and germinating seeds of):
Adults and seeds thrive in 75% peatmoss and 25% sand.
Seeds: Keep them on the drier side of damp (I guess we could say
moist). Make sure you freeze them solid for at least 4 weeks
(though I often froze mine for 3 months). Then, they need to stay
cold for at least 6 weeks (8 would be better). After you take them
out of the fridge, let them sit in a nice and sunny location with at
minimum 5 hours of direct exposure. You should see your babies in
about 3 weeks and they should be really noticable after 4 weeks.
Adults (and about a month after seeds germinate): Wet. Really,
really, damp. Excessively moist. Did I emphasize that the should
not be anything other than wet? I used a plastic container (an old
cottage cheese tub) with a hole punched in the bottom with a small
nail (about a 1/4 of an inch wide) and left this in a saucer. I'd
water the plant until water seeped out. Then I'd leave it standing
that way until the water in the saucer evaporated and I would top it
up.
Hope this helps!

[snip]
Mealy bug infestations are really a chronic problem for those who keep a
variety of plants and continue to get new ones. In my experience, it is
impossible to kill them completely with any procedure, but I get reasonable
control by alternate spraying with soap solutions (1% by weight of any soft
potassium salt soap is OK - it should not be scented and I like the soft
laundry soaps the best - if in doubt, use Safer's)
and then alternate with an alcohol/ammonia/water mix. (I use denatured
ethanol and household ammonia - 1 part each by volume with three parts
water). Rubbing alcohol (propanol) also will work. I think Wood alcohol
(methanol) is too toxic to spray indoors. I have also used cheap vodka or
cheap brandy, appropriately diluted. 20% alcohol solutions will not burn but
higher concentrations can be ignited and over 50% in water can explode!!
when it is sprayed near a source of ignition.
I spray the whole plant and wash off the soap solution with a water spray.
For fleshy plants in dire straits you can dip them into very hot water (50
-55 deg C) for no more than two minutes. Use a timer!! and then dip them
immediately into ice water for a minute or two to cool them. This works for
me about half the time.
This Spring, I am trying a spray of carnivorous nematodes on a batch of
infested Cactus that are in cold storage for the winter. I will apply it
just before I start warming them up. I'll get back if it seems to work.
And relax - when computers try to take over the world, mealy bugs will be
there, well adapted to eat some organic component on them and possibly save
humankind [b-)] - John

Subject: Fossil CP's in Siberia
Hi:
This week, a scientific expedition in Siberia found evidence of carnivorous
plants in Siberia. A team of six university students were led to an
outcropping in the ice. After using a portable generator and blow dryers,
they discovered the frozen remains of the largest Nepenthes anyone has ever
seen. Apparently, it had traps nearly twelve feet long and nine feet wide.
They concluded that Siberia had at one time been entirely tropical. And,
they now know why the Woolly Mammoths had disappeared. In one of the frozen
traps, they found the remains of a juvenile Woolly Mammoth - still asleep
after it had fallen into the trap and had been drugged. The trap apparently
contained small carrots, alfalfa, apples, bananas, and marijuana, which the
plant had symbiotically manufactured to lure the hairy elephants. In
another trap, they were startled to discover three frozen Neantherthal
teenagers who had ignored the carrots, alfalfa, apples, and bananas, and had
gone straight for the marijuana. The scientists now believe the
disappearance of the Woolly Mammoths and the Neanderthals may be linked. A
third trap was partially decomposed but revealed even more - a cro-Magnon
skull, a submachine gun, two hand grenades, a cannister of mustard gas, and
a stinger missile. This discovery means that early proto-humans may have
been much more violent and scientifically advanced than previously thought.
And, it could very well mean that we are genetically pre-disposed to
inventing weapons of mass destruction, letting us all off the hook for the
past six thousand years of negative behavior. The university team plans to
send another expedition to Antarctica next year. Says one of the students
"Now that we've seen this, there could be anything under the Ross Ice
Shelf!"

Consider the chromosome counts; Aldrovanda 2n = 48, Dionaea 2n = 32. The
basic number in common is 8. Aldrovanda is a hexaploid, 6 X 8 = 48.
Dionaea is a tetraploid, 4 X 8 = 32. Remember the ploidy rule; the higher
ploidy in a line of lineage is more recent. Aldrovanda is then younger
and more probably evolved from or split off from the proto-Dionaea line
more recently. So most probable is the line beginning with Drosera to
Dionaea and then Aldrovanda. This is my own theory which you will not
find in literature.

Subject: Re: #%*~/*! mealybugs
Hello Walter and everyone,
I couldn't find any site that provides translations of common names of plant
pests into different languages. Perhaps someone else will know of one.
I'm sure if you've been growing plants for any length of time you've met
mealybugs. They are a small, but easily visible, soft-bodied, sucking insects
that are covered in a white waxy coating, which makes them look as if they
have been dusted in flour, hence the name "mealy"-bug. The most common types
are of the genus _Pseudococcus_. The cochineal insect is a mealy bug of
cactus, and gives us a red dye of the same name.
I've grown Hoyas for many years and have lots of ( too much ) experience with
these difficult pests. For real control, I find rubbing alcohol ( isopropyl )
useless, and far too time consuming besides. It might work if you have a new
infestation with just a few individual bugs, but don't count on it.
They usually cluster in the axils of the leaves and stems and anyplace else
that gives them some shelter. They will hide inside the pitchers of
carnivorous plants. Mealybugs breed very quickly and their offspring quickly
colonize the roots of plants too. Any time you find mealies, you should pull
the plant out of the pot and inspect for signs of the pest on the roots.
These root infestations mean that there are always more bugs to re-infest the
upper parts of the plant. Mealybugs have been a greenhouse pest for so long
that they have developed resistance to common pesticides. This explains why
they reoccur so frequently.
The only effective control I have found for mealies on Hoyas are granular
systemic insecticides. These systemics are hideously toxic; you should not
use them if you have children of pets that might have access to the treated
plants. After applying them to the soil you should not touch the soil without
gloves for a number of months. While this treatment sounds pretty drastic, I
have never found anything else that really works to eliminate the stubborn
little pests.
Systemics vary in their plant toxicity. I have not tried the systemics on
carnivorous plants and cannot say if they might cause serious damage. I would
not try them on _Drosera_ or _Pinguicula_, but might experiment on
_Nepenthes_ and _Sarracenia_ that I didn't value highly.
Alternate treatments for mealybugs control include biological control with a
predatory beetle, _Cryptolaemus_ and various parasitic wasps. Neither provide
complete eradication. You might try submerging the whole plant under water
for a few days.
While in Hawaii recently, I saw mealybugs bigger than an American penny (
about 2 cm. across ). I guess we should count our blessings that we just
have to deal with the little ones.
Cheers,
David

fact three different counts (30, 32, and 33) for _Dionaea_, and two
(38 and 48) for _ Aldrovanda_ (for references, see cp db).
30= 2x3x5 (diploid with base 15 or triploid, base 10) 32=2x2x2x2x2
(diploid, base 16 or tetraploid, base 8) 33=3x11 (triploid, base 11)
38=2x19 (diploid, base 19) 48=2x2x2x2x3 (diploid, base 24 or tetraploid,
base 12 or triploid, base 16 or hexaploid, base 8)
And all these possible (but certainly not equally realistic)
interpretations do not yet consider chromosome loss, fusion, or
fragmentation (which is quite common in some species of _Drosera_)
or simply wrong counts (that may occasionally occur).
A considerable number of fossil species of _Aldrovanda_ is known
(from fossil seeds), forming progressive series as well as extinct
side branches, so _A. vesiculosa_ is quite certainly not a direct
descendant of any representative of the recent genera _Drosera_ or
_Dionaea_.

This simple rule applies *only* to ploidy series within a group of
closely related species of fairly recent divergence, and quite
probably not to genera as distinct from each other as _A._ & _D._.

Maybe, but even _Aldrovanda_ is probably (if the fossil attributions
are correct) at least of Upper Cretaceous age (=very old for
flowering plants).

The conclusion may in fact be correct (especially the assumption
that _Drosera_ is the oldest genus). But I doubt the (oversimplified)
premises, and would rather base this theory on the number of recent
species, sections, and subgenera, and their global distribution.
Chromosome counts of "outgroups" like _Drosophyllum_ (12=2x2x3),
_Triphyophyllum_ (24=2x2x2x3, and 32=2x2x2x2x2), and _Nepenthes_
(80=2x2x2x2x5), could possibly support a number of several
conflicting theories, as the assumedly primitive species of _Drosera_
(a genus of quite crucial importance for Droseraceae evolution) have
counts of 34 (=2x17!! _D. regia_), 22 (=2x11, _D. glanduligera_), 20
(=2x2x5, _D. arcturi_, _D. burmannii_), or 12 (=2x2x3, _D.
petiolaris_, _D. banksii_).
> This is my own theory which you will not find in literature.
You will find it (or at least parts of it) in the papers you have
written yourself (e.g. in CPN).
Chromosome counts are not always very informative (or are they?):
_Sarracenia_ (26=2x13)
_Darlingtonia_ (30=2x3x5)
_Heliamphora_ (42=2x3x7)
Genetic comparison has led to a phylogenetic reconstruction with
_Darlingtonia_ branching first, whereas most morphologists
considered _Heliamphora_ to be the most primitive genus in
Sarraceniaceae...

Subject: mealybug control
Hi all,
I find infestations of mealybugs on orchids and CPs that I grow indoors,
especially in enclosed terraria or wardian cases. The mealybugs are
much less prevalent on orchids and CPs (mostly Nepenthes) that I grow
outside.
After trying various insecticides (pyrethrins and similar), I settled
on Neem oil and Neem extracts like BioNeem (containing Azadirachtin),
after hearing from an orchid grower that Neem gives good results
against mealybugs in Paphiopedilum collections and doesn't appear
to harm the orchids.
Either concoction gives good control though not total eradication.
I remove the most obvious mealybugs by hand, using a swab and alcohol,
or a swab and dilute Neem solution, and then spray the plants and the
surface of their growing medium. This treatment will last a month or
sometimes longer until I see evidence of a few new mealybugs. If I
spray every two weeks, I never see the bugs. Presumably a few are still
lurking, and the population will rebound if I stop spraying, but I
think indoors, a careful Neem spray regimen could eliminate the bugs.
I sprayed the plants in one Wardian case every two weeks for two months,
and haven't seen any mealybugs for six months. In another case, I spray
only occasionally, and the bugs come back. Hmm.
Neem is a tropical tree that is highly touted as having "natural" or
"organic" insecticidal and anti-fungal properties. (Of course, many
"natural" plant extracts are very dangerous, like strychnine or ricin.)
Anyway, the Neem oil is pressed from the seeds, and the extract taken
from the oil. Its main ingredient is an insect growth regulator,
azadiractin, though the oil has a brew of various and sundry other
biologically active compounds. The labeling has a Caution warning.
It is classified in Toxicity Class IV - relatively non-toxic. The
undiluted oil can be irritating to eyes and skin, and for those is
in class III, slightly toxic. Neem's main drawback, in my opinion,
is that it smells like rotten garlic. That's why I don't spray it as
often on the fragrant orchids in one wardian case - I prefer to smell
the orchids, not the Neem oil.
I haven't noticed any harm to the orchids or Nepenthes I have sprayed
with Neem oil solution or BioNeem (which seems to work as well on
mealybugs and doesn't smell quite as bad). I haven't tried it on
Drosera or Pinguicula; they may be more sensitive.
In contrast, disulfoton, the insecticide usually found those systemic
granules, is in Toxicity Class 1 - Highly Toxic. It is highly toxic to
mammals, as well as to insects. It has a very low LD-50, the lethal dose
in 50% of cases, of 2mg to 12mg per kilogram of body weight. This is
measured in rats, which may be more resistant than humans. The label
has a Danger or Danger-Poison warning in the higher concentrations.
In lower concentrations it squeaks by as Level II, moderately toxic,
with a Warning label. I agree with David Gray's warnings and cautions
about the stuff. It may be the only thing that will stop a particular
infestation of scale or whatever, but one should be highly prudent
in using it.

Hi Chuck,
In Germany there is a Insecticide from BAYER ( CONFIDOR ) with the same
active ingredient as Marathon ( Imadacloprid ). After some years of
frustrating trials with some other insecticides and only the loss of all
leaves of my Adeniums full of scales I tried some months ago Confidor
with a fantastic success. All scales are away with only one spraying, no
loss of leaves and the Adeniums are healthy. I heard from this insecticide
from cactus-friends. They know it fore years against mealy-bugs. I know
that mealy-bugs are related to scales and decided to try it and I am
happy.
Perhaps you could get in US CONFIDOR perhaps under another name it is

Charles and all,
I have seen evidence to sustain what Charles said, because of
something I mentioned before about Nepenthes and Sarracenia from
Florida greenhouses. The mealy bugs are not thriving down there, but
when I put the plants in my indoor tanks, BOOM, they appear in about a
month or so. So it's seems to me, that they thrive in softer,

Subject: RE: Tips on growing Cephalotus
Steve,
I have been growing and the Cephalotus for some time now. Actually, more
years then I care to say. Anyway, here is some helpful hints that may help
you with your problems: Avoid purchasing bare rooted Cephs in the future. If
they do come bare rooted, soak them in a fungicide solution for approx. 10
minutes before planting them up. A good fungicide to use is Ortho 3336.
I use a soil mix consisting of 40% dried chopped sphagnum, 40% perlite, 10%
sand/peat moss mix with agriculture charcoal mixed in. Add water, mix the
soil and water together and let stand for approx. 1 day before using. Fill
pot 60% full with mix, top dress soil with live sphagnum, plant your Ceph,
water your plant and allow excess water to drain. Place potted plant in a
cool humid environment, out of direct sunlight, until the plant shows signs
of new growth. Forty to 75 degree F condition is excellent. Actually, cool
nights, warm days are ideal for these plants. All my plants do their best
growing during winter months. Their growing chambers reaches 70 degrees F
during the day and drops to as low as 35 degree F during the evening hours.
I also grow Cephs in my greenhouse where the temps can drop as low as 28
degrees during the evening hour. Air movement and well drained soil seems to
be essential for healthy growth.
> Will the plants come back if treated properly?
If the rhizome is healthy enough and you don't keep the plant to
wet, it should.
> Is there any special R&R I can do to help?
Once planted, leave it alone.
> Should the rhizome be planted
> parallel or perpendicular to the soil surface?
Vertical seems to work for me.
Things to avoid: Keeping them to wet, high temperatures, over
feeding with insects especially when growing them in an environment like an
aquarium. Constantly moving them around or repotting them, soil mix to
compact, sour soil, using strong fertilizers, full sun.
Hope this helps, Charles Brewer

The web site you may be referring to is my old web site catalani.com. I grow
quite a few cephalotus, and over the past few years have experimented with
growing them at different temperatures. My largest cephalotus's still grow
year round at 80 degrees. However, I have found that transplanting plants,
especially bare root, is best done by keeping the humidity extremely high,
and keeping the plants out of any form of direct sunlight until they are well
established. This usually allows them to keep their pitchers. Immediately
exposing them to high light aftre transplanting can cause the pitchers to
wilt in a few days, although the plant itself is ok. A lowland Nepenthes
house may not provide enough light for the plants, and with ample humidity,
bortrytis could become a problem, especially at 85 degrees. Mine grow at that
temperature under lights, and I havent had a problem with fungus attacks.
Placing the plant next to a heater or heater fan could reduce the humidty and
dry the plant out (the leaves, ont the soil), which ceph's defintely do not
like. They are quite durable from the roots, and can easily come back from
the "dead". I'm not sure what effects sulfur may have on the plants. Be
careful about leaving the plants outside as well. I can grow cephs outside
here in Memphis during the early spring, but other times of the year it is
either too hot or too cold. My large plants grow in a chamber inside my
house. This keeps the temperature stable at about 75 degrees. With the lights
on, the temperatures rise to about 85 with some flux up and down. My point
about this is that the chamber isnt heated on the inside, which keeps the
humidity from dropping.

Subject: Legal(?) Sarracenia trade
Hey Folks,
I have just finished helping a plant quarantine officer for the US
Department of Agriculture. The officer had questions about the
identification of some plants being sent through his office. We were able
to establish that the plants were most probably Sarracenia rubra subsp.
rubra---I was particularly concerned they may have been Sarracenia
jonesii.
Since the plants were apparently Sarracenia rubra, the papers were in
order so the plants passed through the USDA station without incident.
However, I have grave misgivings about the entire episode. As I understand
the particulars of the shipment, approximately 500 plants were being
shipped to Canada, in dead and dried form. (Presumably for some
pharmaceutical purpose.)
Were the plants field collected or propagated, you may ask...
It is impossible to tell. But there is a clue... The plants were mature,
and at least some had mature fruiting capsules. Since the seed capsules
were not harvested, this suggests the plants were field collected---an
operation involved in large scale propagation using seed would probably
collect seed capsules. If the plants were being grown out from tissue
culture, I would expect that the flowering stalks would be removed in
early development for maximum growth of the rhizomes.
So....my guess is the plants were collected from the field.
Perhaps the plants were field collected legally. In any event, it was an
interesting incident.
Sigh.

Subject: Re: Aldrovanda and Dionaea
Filippo and Ivan,
So the question is, did the snap traps of VFTs and Aldrovanda
have a common or separate origin? Well, phylogenetics usually goes by the
assumption that evolutionary changes are more likely to have accurred once,
rather than twice independently. So simplyfying the question, we assume that
snap traps arose only once.
BUT -- and there always are one or more buts -- there are
several characteristics which put Aldrovanda closer to Drosera than to
Dionaea, such as style number and pollen morphology. This suggests that
maybe the snap traps of Aldrovanda and VFTs evolved from a sticky
predecessor (common to Drosophyllum and Triphyophyllum as well -- and maybe
even Nepenthes, as indicated by DNA sequencing) AND...... that Drosera
evolved through a reversal of the snap trap back to the sticky (although
active)trap type.
As you see, this reversal seems as unlikely as the possibility
that two different snap traps evolved independently in the same family. If
there were more snap traps in the CP world, maybe this wouldn't sound so
improbable. Both are POSSIBLE, but UNLIKELY. Agree?
So what does DNA show us that morphology hasn't so far? Well,
the phylogenetic trees I obtained with after sequencing two genes have so
far not been 100% conclusive. In fact it would be best to sequence one or
two more genes to be sure, to add more data. It's pointing to either of two
possibilities (hopefully this very crude tree will come out well...):
Tree #1:
Neps VFT Ald.
/_______/_____/____ Dros.
\
/ \_Tryphyoph.
/
Drosoph.
OR
Tree #2:
VFT Ald.
\ /
Neps \/
/_______/____ Dros.
\
/ \_Tryphyoph.
/
Drosoph.
Tree #1 shows VFT and Ald. inserted as 2 separate branches onto
the main stem. This could mean that snap traps had a separate and
independent origin from sticky traps OR that there was a single snap trap
origin from sticky traps and that the sticky traps of Drosera evolved from
some sort of snap trap. A step back, some might say, but I guess the fact
that we only have two snap traps alive today suggests that maybe the energy
spent is not as evolutionarily efficient as active sticky traps. Anyways, in
this case (tree #1) it is more likely (in terms of evolutionary steps
necessary) that the second possibility is true, since a snap trap would
require numerous adaptive mutations to evolve. The chances that this
happened twice in parallel are scarce. Regression on the other hand is far
more likely since at least some of the mutations necessary for regression
may already be present, retained somewhere in the genome, maybe inactivated.
Anyways, tree #2 shows Ald. and VFT arising from a common
branch, which is in turn inserted in the main stem which leads to Drosera.
The big difference here is that this tree increases the likelyhood that snap
traps had a common origin (since they're on a same branch) and decreases the
likelihood that Drosera evolved from a snap trap (but from a passive sticky
trap instead). Again the possibilities are there, so we can only bet on the
probabilities. On or two genes might not be conclusive. But add a few more
genes and if they keep pointing in the same direction, I guess it may not be
necessary to sequence their whole genomes... :):):)

Interesting, but you should include _Ancistrocladus_ in your
analysis. It is the closest relative of Dioncophyllaceae, and this
further proves that _Drosophyllum_ (which is the sister to the
Dioncophyllaceae/Ancistrocladaceae branch) is not part of
Droseraceae (i.e. the family did probably *not* evolve from a
_Drosophyllum_-like precursor).
More importantly, you should include a non-nepenthalean outgroup in
your considerations. Otherwise, the tree is unrooted, and the
evolutionary course could equally well have been in the opposite
direction, e.g. Meimberg & al. (Plant Biology 2:218-228, 2000) came
to this conclusion:
/Nepenthaceae
|
| /Ancistrocladaceae
|/+
/+|\Dioncophyllaceae

i.e. Droseraceae are at the base and not at the top of the

Is _Drosera_ monophyletic (incl. _D. regia_) in your trees?

Also separate origin of pitchers is unlikely, but there is the case of
Sarraceniaceae, Cephalotus and Nepenthes which almost surely developed their
traps indipendently.
Why the same thing couldn't have happened to snap traps?
Drosera traps seem quite suitable for such evolution: consider for example
D. kenneallyi: its traps have a shape very similar to the one of Dionaea's;
and when they catch prey they close in the same way.
If you add to it the rapidity of D. burmannii and if you increase it, you'll
maybe obtain one day another snap trap evolved indipendently.
About Aldrovanda, it is clearly related to Drosera, but it is completely
different morphologically; and this is obvious if you admit the very ancient
origin of this genus.
Dionaea, on the other hand, is still very similar to some species of the
genus Drosera, which should be very strange if the two genera separated more
than 65 millions years ago.
Just some ideas, without scientific bases.

but that's not bad for a plant that was sitting in dried sphagnum at
the local Home Depot store!).
Is this common for this plant? I mean, I'm not complaining, but
space is a factor and I hate the thought of having to "dispose" of
the excess.

Jk,
No, it is definitely not just you. D. adelae produces gazillions of
plantlets that will fill the pot up and shoot out the pots drainage
holes and start growing across the bare glass of my tanks. I should
put a layer of LF sphagnum on the bottom of the tank so they plantlets
could get huge. It is one of the most prolific CP, in that to
propagate it, you don't have to do anything. It does all the work. I
would not dump the excess. Maybe you could trade them on the trading
post or at least give them to new people interested in CP(or charge a
buck a potful). I had a similar episode with U. longifolia, and I got
rid of it in a quick manner, only to find out a few weeks ago that
mine flowered much more than others were known to(thanks to Barry's
wisdom, even though he called me a "Infidel" :( )

Subject: Refridgerated Seeds and Fungus
I bought a whole mess of VF seeds (20,000 from one of the list members),
put them in Perlite, dampened the whole mess with water and fungicide,
drained any free water and put the sealed mass in the refrigerator for a
few months until I could find 20,000 pots to put them in. I brought them
out yesterday to inspect them and noticed a thinish layer of fungus on
the top of the seed/perlite mass. All the seeds still look shiny and
plump, and the fungus doesn't appear to have reached too far below the
surface - kinda like turf - could the perlite itself have nutrients that
the fungus can grow on, and why, if I bathed the whole thing in bonomyl
fungicide, did the fungus start growing? Does the fungicide wear off
after a while? I plan on test planting selected seeds to see if they've
been damaged. I hope not...

Subject: Sphagnum Palms?
A little while ago, I reported that I had been using "peat" bricks which
contained coconut fibre (coir).
A more careful look at the label (Tropigro "Fast Peat" bricks) shows that
these bricks are made entirely from coconut fibre.
I was under the impression the term "peat" applied exclusively to sphagnum
moss peat. If these bricks are "peat", then I have a 50 foot sphagnum moss
palm growing in my back yard and, I tell you what, you don't want to be
standing under it when it's dropping its spores.
Apart from the (mis)use of terminology, I don't have any complaints about
the bricks. I suspect the coconut peat lasts longer in the tropics. And
if you're into using coconut, it's much easier than trying to snip up
coconut fibre with scissors.
BTW, a way of controlling ants on Nepenthes (or any other plant for that
matter) is to place the plant in the centre of a moat.

Mr. Webster says that peat is
"Turf or partially carbonized vegetable tissue formed by partial decomposition
of various plants (as mosses of the genus Sphagnum)."
Yet another definition:
"A bold, gay woman."

So, I guess partially decomposed coconut fiber is 'legal' to sell as peat.

Boy howdy,
Thanks for the overwhelming response to my mealy bug questions. I am glad to
hear so many others also rely on the tried and true firehose technique of
crowd control. I may also try spraying alcohol, instead of just dabbing it
on. A couple of days ago, I also found a bottle of concentrated liquid
garlic juice. I am guessing this would work more as a deterrent than a cure.
I am still curious where they come from...or are they just native to
everywhere by now? I have seen articles that Hibiscus mealy are a problem in
the Caribbean, but also that mealies attack fruit crops in the Pacific
Northwest. Can they survive outdoors in Chicago over winter (long stretches
of 10-15F)? Also, I see Australian Mealy Bug Destroyers (aka Ladybugs) are
available but expensive. Do other kinds of Ladybug eat mealies if available?
Lots of Ladybugs huddle together and overwinter in my Sarracenia
pitchers...I have caught and released these in my plant room before, but
have never seen one eating anything, let alone a mealy.
Once again, any information is appreciated,

I believe there are seven species of Drosera in the USA, but perhaps
this is the count for North America: D. anglica, D. brevifolia, D.
capillaris, D. intermedia, D. filiformis, D. linearis and D.rotundifolia.

Mine started out in a sphagnum/peat mix, but now I think my U. Longifolia
is mostly growing in U. Longifolia. Actually, I take that back. It's
mostly growing in the water tray. I got mine originally from a pot
of D. Prolifera. I wish the Prolifera had done so well. Mr. D'Amato
ID'ed it for me, so I'm pretty confident it's U. Longifolia. Neat
stuff. Huge traps. No flowers, though.

Whoops. Sorry about the post to the group that was supposed to be
private I knew I would do that sometime. Anyway, a couple of people
have inquired to what I did with U. longifolia. Honestly, I basicaly
neglected it. I started ICPS seed in a pot of milled sphagnum, and it
germinated and grew and then invaded nearby pots of D. prolifera(I
guess they love prolifera, huh?) and D. villosa and stangled them put
of existance, and then shot out the bottom of the pots and covered the
entire bottom of a 10 gallon tank(bare, except for the pots). I would
dump water in occasionally, when it was dry(sometimes the leaves were
brown a little). The bottom of the tank was a inch-thick mass of
whiteness. The photoperiod was a straight 16 hours with no fiddling
with it for seasonal purposes. Deduce what you can from that. he
other pots had a variety of mediums from LF sphagnum to peat/sand, but
it did not matter. Maybe the exposure to so much oxygen had something
to do with it, or because there was nowhere else for the plant to go,
they had to flower because they were bored :) Maybe periods of d!

at most plant nurseries. They should be released at night. They will be
hungry in the morning and will start chomping at first light. It's best to
release 100 or so at a time, keeping the rest in your fridge. They tend to
migrate rather than stay put in your plant area, that's why it's best to
release them in bunches over time. Alcohol spraying is cheaper and, I

Hi all, Ivan again,
I feel the most exciting findings are yet to come. Considering all that
we know, and some experiments I have done, it seems most likely that
Aldrovanda and Dionaea can be hybridized. The results of such an attempt
would be telling in regard to their taxonomic relation and also might
lead to some interesting plants for the cultivator. Can you imagine how
such a hybrid would look? Since hybrids are intermediate in appearance, I
like to think that a hybrid would also look like the evolutionary
in-between.

I think perhaps the onus should be on the exporter to prove they are
from cultivated sources rather than the opposite. It should be fairly
easy to provide evidence of growth in cultivation - a nursery premises

Subject: re: U. longifolia
Hi,
Sorry for dropping in, but I have a question that someone of you might
answer. Can the leaf shape be variable on this species under it's
development from a juvenile to a mature plant?
The reason I'm asking is that I received a juvenile U. longifolia (White
flower, Serra da Araponga) late last year. It has been doing great so
far and the leaves has grown quite a bit. When I first got it, the small
leaves were long and thin like I had expected, but the latest leaves are
much stockier. I just wondered if this is normal or if it might be an
invironmental thing.
BTW, I have also got an U. alpina that have an almost round "leaf" as
well as the normal elongated foliage. Since the "leaf" has traps it must
be an utric, but there is always the possibility that another species
has invaded the pot.

Subject: P. zecheri leaf cutting?
Hi,
I've read that one should use the succulent winter leaves on Mexican
pinguicula for leaf cuttings, but is it possible to be successful with
trapping leaves, since P. zecheri doesn't grow a winter rosette? My
plant has grown a larger number of smaller leaves lately and I thought
that it would be good time to propagate by leaf cuttings if it viable.

Yes, leaf shape can alter as the plant gets larger and older. Another
thing that can affect leaf shape and size (and flower size as well) is
relative humidity. Generally the more humid the conditions the larger
the leaf.

Yes you can use the larger carnivorous leaves, though success is likely
to be lower than with the succulent winter leaves. The main reason for
using the winter leaves is that in the spring they will produce
adventitious buds at their base, which is where the new plants grow
from. Its really to do with timing rather than the actual leaf type.

>>Also separate origin of pitchers is unlikely, but there is the case of

Why the same thing couldn't have happened to snap traps?
Drosera traps seem quite suitable for such evolution: consider for
example
D. kenneallyi: its traps have a shape very similar to the one of
Dionaea's;
and when they catch prey they close in the same way.
If you add to it the rapidity of D. burmannii and if you increase it,
you'll
maybe obtain one day another snap trap evolved indipendently.
Filippo Tassara
Hi Filippo and all,
Your question is valid. The answer is a probability only. I grow
Aldrovanda, Dionaea and sundews and have a particular interest in
studying their relationship. I believe that the gin trap evolved only
once. Here are the main reasons why. 1) Firstly, it is most reasonable
that the aquatic Aldrovanda trap evolved from a trap more like Dionaea's
out of water because the sundew trap does not function at all under
water. There must have first been a trap more like Dionaea's to begin
with which gave rise to Aldrovanda's. So the most logical order is
Sundew-Dionaea-Aldrovanda. 2) Secondly, as I pointed out before, the
chromosome counts of Aldrovanda 2n = 48 hexaploid [BTW Jan, triploids are
sterile] and Dionaea 2n = 32 tetraploid enforce reason number one.
3)Third and last, Fernando's DNA sequencing shows that Dionaea and
Aldrovanda are indeed very close.
It is true that Aldrovanda's flower is more like a sundew's. This is
the obstacle I think is troubling you. I reconcile this by what Jan says,
"these evolved long ago"; so the split must have occurred before Dionaea
was as it is presently. The proto-Dionaea surely had a flower much like
Aldrovanda's. Hope this clears things up.

Very true! I think your conditions are very good for cultivating
Nepenthes in this manner. Especially your water and seasons...
Greenhouses are much more trouble in the north (think heating over
winter) and water is hard for the most part. _Sphagnum_ tends to rot over
winter when brought inside and is difficult to keep "fresh". Instead of
buying an R/O unit, I just use a peatmoss heavy soil for _Nepenthes_ as
Sphagnum doesn't last over time without pure water.
I'm glad my plants 'grow much more slowly' actually. They are all
inside and if they were fast growing, they would have taken over by now!

Subject: Re: P. oblongiloba
Hi Jo.
The species Pinguicula oblongiloba is from Mexico, now there's a
surprise! Like most of the mexican species, it grows high up so despite
Mexico being thought of as very hot, the highland climate is somewhat
cooler. In fact, days will be hot and nights relatively very cold,
though there's no real risk of freezing. It's got a fairly typical
Pinguicula-like rosette and a flower that is a very typical
purple-violet, again like many Pinguicula. The flower is held erect but
this species can have a very long flower stalk, though not every plant
shows this. Rests in winter with the dormant non-trapping leaves
usually just under the soil surface and visible from above (unlike some
species which really do bury themselves where they can't be seen).
In cultivation it will enjoy typical "mexican type" cultivation which
will be: warm days (I doubt you could easily overheat it as all my
tender Pinguicula species suffr temperatures as high as 120F in summer
without loss), cooler nights - 5 degree C minimum at any time of year
(41F for all decimally challenged brethrin!!!) but I always recommend
slightly higher especially if there is any risk plant might be in wet
soil in winter. Use a mix of Peat (20%), Sand(10%), Perlite (50%),
Vermiculite (10%), Loam (10%) but treat the volumes as approximate - the
idea is to have a soil that gets wet easily, stays damp for a good time
but freely drains. (At an extreme, I would expect the plant to survive
in 20%loam and 80% Perlite. It certainly won't have Vermiculite or Peat
in it's wild habitat, nor much sand.) Water until soil is wet. Then
allow soil to dry before watering again. In summer the plant will
appreciate about 12-13 hours bright light. In winter, drop to about 7
hours and water less frequently allowing the soil to remain dry for days
(I allow about a week for similar species) before rewetting.

Subject: stalking prey
> Paul Temple, take it away......
Damn!
Oh well, yet another area of my ignorance exposed!!!
I don't recall that any f my Pinguicula ever displayed bare flower stalks. From memory all have glands and insects are quite
frequently trapped. It makes sense for such succulent (I mean this in the cullenary sense) plants to protect themselves from
ravaging insects.
As to wheher the glands can digest, on this I am no expert (though note that this does not iply I'm expert on anything else!!!),
though I'll now read more on it and related topics. Two points. First, most of the books (I've not re-checked them all)
completely avoid this subject. They simply refer to the leaves. This includes avoidance by some of the more scientific (rather
than popular) titles written by full time botanists.
However, the second point is that Pinguicula are rapid feeders. They
very quickly digest and absorb their prey having first poured out a
small pool of digestive enzymes to help things along. A pool of liquid
enzyme would not be too stable if secreted onto a vertcal flower stalk.
So it's unlikely that Pinguicula would have evolved to waste too much
energy on using the flower stalk as a digestive area as much of the
digestive pool of enzymes, and the resulting pool of digested prey,
would run off.
I'm sure one of our resident full time botanists must have read more on this?

Subject: Nepenthes in Sphagnum
Hello Dave, and list,
FWIW, I grew up and learned about horticulture in Boulder,Colorado. Cold
winters are not something I am unfamiliar with. We were fortunate to have
very soft mineral free water that came directly off glaciers to use as tap
water, when I was young. This was before human population levels in this
area made ground water sources a necessity. Before I left Colorado, the tap
water was hard enough to make me purchase an RO unit, this was in 1978. The
change in water quality was very evident in horticulture, and Sphagnum did
break down, and become sour. I agree, fast growing Nepenthes are not always
desireable, when faced with cramped conditions. This does not change the
fact that many Nepenthes species and hybrids grow better in live Sphagnum,
in horticuture, than in other mixes, when placed and grown in proper
conditions. Sphagnum also grows and thrives when in proper conditions. I
believe people should find whatever mix and method they have the best
success with and utilize these with an observant eye and open mind.
Take care,
Steven Stewart

Yes I agree with the point about wetting a plant with fungicide
potentially adding to the problem. I use regular sulphur, sold in just
about any garden centre, usually for dusting spring bulbs and other cold
sensitive plants that are lifted and stored for the winter.
The sulphur goes on dry and seems far more effective than any other
fungicide that I have used. I think part of the effectiveness is because
the sulphur will form a barrier to prevent re-infection.
As to your plant I would take emergency action. Remove the plant from
its pot and cut away all decaying growth until you are left with only
healthy material. Plant up in fresh soil, treat the plant with the
sulphur and hope! Even if you only have a small piece of rhizome left
there is a good chance that the plant will recover. Its not long until
spring now.
As to reasons - Cephalotus does die back in this way for no apparent
reason.

If you dig around the bases of the leaves you should be able to expose
enough of the petiole for the leaf to break of easily. If you grow the
plant in an alkaline substrate it will produce far better roots - you'll
be able to pick the plant up by its leaves - pot and all!

Hi Joe,
P. oblongiloba is actually known for more than a century with the type
specimen described in 1874. It is present in several states in Mexico:
Durango, Jalisco, Michoacan, Mexico, oaxaca and maybe more which I'm not
aware of.
P. oblongiloba was classified by Casper with P. macrophylla in a subsection
called caudatopsis of section orcheosanthus (contains the very well known
P. moranensis which you should find in the Salvage garden) of the subgenus
Pinguicula of genus Pinguicula. P. stolonifera has later been added to this
subsection. But this classification is based on morphological characters
and not growing conditions. Still, P. oblongiloba is not a difficult
species to grow. I used to cultivate it like P. gypsicola (also part of
section orcheosanthus) or P. macrophylla. Make a more open mix and dry more
in the winter than recommended for P. moranensis even though P. moranensis
would prefer such conditions too.
I hope this helps. It is a nice plant.

Your fungus is due to the 100% (or nearly 100%) humidity caused by sealing

Do you think it could be possible to identify field collected Sarracenia,

in the pitchers? Perhaps the relative abundance of insects or the
taxonomic groups would be useful.
Dan Murphy>
That is an interesting thought, and one I hadn't thought of. There is a way I
can usually determine whether a Sarracenia plant was field collected or not.
The soil in which they naturally grow (depending on species and location)
can be a very thick "muck". It adheres to the root system and rhizome, and is
very difficult to remove. The first time I encountered this was a decade
ago, as I was transplanting wild flavas from a site being cleared to another
active flava site about a mile downrange. In an old copy of ICPN (or in
Schnells book, I cant remember off the top of my head) it had stated that
when you transplant plants, to thoroughly clean the plant of any soil to
avoid contamination of the new site. This was much easier said than done.
The soil must have clay or similar material in it, as it was very difficult
to remove. Those removing plants from the wild for resale have the same
issues. It is very difficult to remove all of the native "muck" from a
plant. So they either don't remove all of it, or they remove practically all
of the roots from the plant to make the process easier. Sarracenias have an
extensive root system, so lack of genreous root system or the presence the
the black "muck" on the rhizome and root area is normally an indicator that
it recently living in the wild. I'd be interested in hearing of any other
"sleuths" out there who can come up with other ideas to determine whether a
plant is wild collected or not.

The talk of wild collected plants has made me think of a question I had, and
I was wondering if anyone knew the answer to it. Many moons ago, ICPN ran a
story on Cresco Nurseries in Holland, and their extensive CP propagation
efforts. The picture on the cover of ICPN showed a shot inside the
greenhouse in which grew 6 million or so flytraps. In a later edition of
ICPN, an article (I believe by Larry Mellichamp, but not sure) had said that
a Holland nursery featured in ICPN was believed to be mass propagating vft's
until "keen eyes" proved otherwise. I took this to be that someone looking
at the pictures from Cresco in ICPN spotted something to prove that the
flytraps were field collected. Does anyone know if it was Cresco they were
referring to, and if so, what the person saw in the pictures? Was it the
soil they were growing in? Or did they spot a native Carolina plant in a pot
growing with the flytrap?

Dear Barry,

Do you think it could be possible to identify field collected Sarracenia,
as opposed to greenhouse cultivated plants, by the insects that are caught
in the pitchers? Perhaps the relative abundance of insects or the
taxonomic groups would be useful.
Hey Dan,
I doubt it. Someone might be growing their plants out doors, but within
normal Sarracenia range. The prey spectrum would probably be quite
similar.

<< Hi Everyone--
I have a N. maxima that hasn't produced a single new pitcher since its 1/2"
stem started growing (currently 8" tall and 2 feet across). There remains a
single fully developed pitcher about 6" from the ground rosette, and 8 upper
leaves with stiff tendrils and no sign of enlarging pitchers. They haven't
browned or dessicated in any way, and because the plant pitchered fine under
the same growing conditions earlier, I'm assuming the humidity and temps are
okay--although recently with the energy crisis, house temps have fallen into
the 50 degree fahrenheit range, but the plant wasn't pitchering even before
then. I have the plant in an orchid basket over my kitchen sink and it gets
full morning sun for several hours. Other than the basket wires which the
petioles have leaned themselves on, there is no support for the tough stem.
Could this be my problem? Have any of you experienced a stubborn to pitcher

I have malesiana's maximas in my highland nep house (even have the lowland
forms) and I can tell you that the 50 degree nights wont be a problem as long
as the day temps can exceed 70 degrees. If the tendrils are short (2-3
inches) the problem could be that the day temps are a little cool. (My plants
have experienced The plant may also be preparing to flower now, as every
flowering size maxima I own right now is in flower. N. maxima's is one
Npenethes that seems to have no problem pitchering even if the tendril doesnt
grab. But I believe from what you describe that the problem may in fact be
humidity related. While the plant was smaller, the local humidity provided by
the soil in the basket allowed pitchers to develop. If the plant has exceed
the size of the pot (or basket), then the local humidity provided by the pot
isn't reaching the tendril ends. This problem may go away as soon a spring
arrives, and the natural humidity in the air begins to rise. (It's normally
very dry in the winter) Or you may try to cover the entire plant in plastic
for a few weeks. That should tell you if its humidity related or not.

Although I, like many of you, admire Peter greatly, the plant did not die
because it flowered in the first year. It died because of its growing
conditions. I've had D. live 3 years and then die because I let it get too
dry. It flowered faithfully each summer. I still have the seed and will
try again.
I grew mine in 10% peat and 90% sand and watered when the soil became almost
completely dry. At times, the plant would wilt because I didn't pay enough
attention to watering it. It recovered each time -- except the last time
when I was gone for 4 days and wasn't around to notice that it went dry.

interested a European focussed plant trading list?
I currently run a UK based plant trading page at my web site (address
below) but have had to turn down adverts in the past from growers living in
Europe as I wanted to keep it specifically UK oriented. I know that there
is a world-wide list that Rick Walker operates but with phytosanitary
certificates being needed when sending plants from Europe to the USA (etc)
it seems a good idea to have a European page so that growers can trade
amongst themselves without this problem.
If anyone is interested then let me know by email (NOT replies to this list
please to cut down on traffic) and if I get enough positive responses I
shall start one up alongside my UK based page.

Interestingly plants in the wild will often apparently die off
completely during the dry season but return to growth once the rains
return. The key to growing this species seems to be to use a large
enough pot so fluctuations in soil moisture during the dry season are
minimised.

I remember years ago that Bob Hanrahan from WIP (World Insectivorous Plants)
did this as well. Doing this properly can be a very good thing, as the site
is managed and taken care of. A peson who buys land to protect these plants
and ensure their survival is doing the plants a service, even if they sell
some of the plants. Over the span of a few years a properly maintained stand
of Sarracenia will generate a tremendous amount of material. Anyone who sells
plants from their own land in which they are actively managing to ensure the
survival of the site should be encouraged to do so. Not only is it legal and
ethical, it should be supported. On the flip side, someone who treks down to
the gulf a few times a year to collect Sarracenia from a site that does not
belong to them, even under the pretense that the site is about to be
destroyed, and sells the plants are doing us, and especially the future of
these plants, a monumental disservice. Sarracenia are very easily propagated,
and can be done so very cheaply. Someone who buys a plot of land in which
Sarracenia naturally grow wouldnt be doing so just to sell off the
Sarracenia plants that were on it, it wouldnt be worth money. They could,
for far less money, develop a greenhouse range and propagate the plants. I
know at times I can sound a little overbearing about field collecting plants.
However, selling ones own plants from one's own land that one is managing is
something that I totally support, and I wish more private owners could get
involved in this way.

Subject: Nepenthes ultra basic soil
Thanks to all the people who responded about my Cephalotus problems. I think
I will experiment with the three struggling pots and keep them under the
various conditions, (40 - 75 Deg. F, 60 - 75 Deg. F, 70 Deg. F), and see
which one does the best. I'll keep you posted.
I am new to the list and read with interest the info about laterite in the
archives. After reading about the soil less Nepenthes mix in last year's
CPN, I decided to try it for myself. Since I don't live in Germany, I had to
substitute components. I found expanded clay pellets for hydroponic orchid
use at the local Home Depot, as well as red volcanic rock. After looking for
a Seramis-like product, I heard about laterite and specifically a baked
laterite product from Seachem called Flourite. These seemed to be too rich
in iron, so I cut the proportion of this in half and substituted white
pumice rock for a final mix of 2:2:1:1 of expanded clay pellets : red
volcanic rock : laterite or Flourite : white pumice with a time-release
fertilizer added per the instructions in the CPN article. I don't have a lot
of extra Nepenthes but I did have three small 2", 3" and 5" N. mirabilis
that I separated from a larger plant with roots intact. I planted the
smallest one in the mix with the Flourite and the 3" in the mix with the
laterite, and the 5" in my standard Nepenthes mix, (below with extra peat
added), in 4" pots. I put them both in a tray with 1/2" of water in a
greenhouse with 70%-80% R.H., 75-90 Degrees F., under two 40 watt
fluorescent bulbs. The smallest plant, in Flourite, died after 3 weeks. I
think this was due to the fertilizer and the size of the plant, (small
roots), and not the Fluorite as I have added Flourite to other plants and
they seem to love it - nice and dark green. The other plant is still growing
strong after four months, having doubled in size. The leaves are darker
green, but the pitchers are smaller than the similar sized, slower growing
plant, in the more traditional mix. I know this is not even close to
scientific method - but it was fun and interesting!
Which brings me to another question. Has anyone tried creating an ultramafic
soil mix? I took my standard Nepenthes recipe: approximately 70% fir bark,
8% red lava rock, 8% white pumice, 7% sand, and 7% peat moss; and added
three pinches of granulated dolomotic lime and a small handful of Flourite
to a 4" pot. The N. rajah got a top dressing and is growing well. The N.
rafflesiana "Giant" also got a top dressing and is growing as slowly as it
was before the treatment. The N. northiana was accidentally uprooted and is
slowly recovering from shock, (hopefully). The N. burbidgeae is growing very
slowly and put out one new leaf that is 1/3 the size of previous leaves,
that were grown in its previous environment before I got the plant. Its
really too soon to make any conclusions, and with no control plants
impossible to make any. Anyone else out there with similar experiments?

could always go check out your excellent article about the subject in CPN!

Humm, I believe pitchers are a whole different story. Like the
sticky leaves of Drosophyllum, Pinguicula, Roridula, and many non-CPs,
pitchers are a relatively "simple" trap type. Maybe not as simple as sticky
leaves, but which certainly take fewer mutations to evolve than something as
complex as a snap-trap which involves fast movement of the lobes and
communication through trigger hairs. Have you ever noticed that one touch to
the trigger hiars does not close a VFT trap? And that water doesn't close it
either, not even a strong spray?? Imagine the celular adaptations involved
here... Not to mention that the traps have to reopen themselves after
digestion and absorption are completed. Pitchers just sit there. They may
release enzymes and absorb nutrients, but the beauty of the traps is
something easily evolved through natural selection by any plant that needs
to attract insects (pollination or predation). The pitcher seems to be a
simple folding of the leaf, if I remember well, shown by the mid-rib "scar"
(although I think maybe Cephalotus might be of peltate origin, an
invagination instead of folding... Jan help me here!). Folding of leaves
into tubular formats does not appear to me to be nearly as specialized as
the A&D leaf morphology. So because it is less "difficult" to evolve is
probably why we see 3 possible evolutionary origins for pitcher traps
(Nepenthaceae, Sarraceniaceae, and Cephalotaceae) and so many sticky traps
with at least a few evolutionary origins.
> About Aldrovanda, it is clearly related to Drosera, but it is completely

If I remember well, detailed morphological studies of the traps
showed instead that they were in fact very similar. Just because one is
aquatic and the other terrestrial does not make them completely different.
Look at Utrics! We've got aquatic, terrestrials, affixed aquatics,
epiphytic, tuberous, rheophytic -- a vast variety of adaptations in a single
genus! And much more recent too, evolution-wise.

Just because it's terrestrial? Flower-wise, Aldrovanda is much
more similar to Drosera than VFT. Pollen-wise too.
> 1) Firstly, it is most reasonable that the aquatic Aldrovanda trap evolved
from a trap more like Dionaea's out of water because the sundew trap does
not function at all under water. There must have first been a trap more like
Dionaea's to begin with which gave rise to Aldrovanda's. So the most logical
order is Sundew-Dionaea-Aldrovanda.
I agree. But just because A is "farther" away from Drosera does
not mean it will be as a whole more different from Drosera. Characters
usually evolve independently. So the ancestor of A&D may not have looked
like either plant, but may have been a mixture of both. So it is not at all
strange that certain characters of A are more like those of Drosera even if
you believe that it evolved from a VFT-like ancestor. So the 5 styles of A
might have been present in the common ancestor of A&D, but was lost in the
VFT lineage (actually, not lost, but incremented in number). On the other
hand the common A&D ancestor was probably terrestrial, but this was lost in
the A lineage as these evolved into aquatic plants. You see? Evolution goes
both ways. All ways. That's why we can't say, for example, that the ancestor
of Drosera looked like Drosophyllum. Their sticky traps probably had a
common evolutionary origin, but both have been evolving separately for
who-knows-how-many-million-years. So some of the Drosophyllum
characteristics may be "primitive" while other may be derived -- and same
with Drosera.
>2) Secondly, as I pointed out before, the chromosome counts of Aldrovanda
2n = 48 hexaploid [BTW Jan, triploids are sterile] and Dionaea 2n = 32
tetraploid enforce reason number one.
This is interesting! Did you find this yourself? Where are the
plants from?
3)Third and last, Fernando's DNA sequencing shows that Dionaea and
Aldrovanda are indeed very close.
Well, it shows they're close, but hasn't yet led me to any
conclusion regarding the two possible family trees I sent previously
(although I do think it's more likely that A&D are on the same branch,
sister to Drosera, showing a single origin of the snap traps).
> It is true that Aldrovanda's flower is more like a sundew's. This is the
obstacle I think is troubling you. I reconcile this by what Jan says, "these
evolved long ago"; so the split must have occurred before Dionaea was as it
is presently. The proto-Dionaea surely had a flower much like Aldrovanda's.
Hope this clears things up.

I consider this plant one of my most important finds. What a fantastic day

were dazzled by loads of U.longifolia covering the boggy, grassy mountain
top -- half of them albino and half normal. Yet "normal" was hardly the

Subject: Artificial Bog and water recirculation...
After several years of being out of the CP cultivation hobby (usual
excuses - got married, went to school, got broke, bought a house,
started a business, etc...) I'm finally getting back into it. For some
reason I'm convinced that live spagnum grown in containers and the
plants grown therein will grow better if the water is flowing and have
devised a little submerged pump in a 10gal reservoir and a drain system
that will circulate rain-water through several 4" deep containers into
which I'll plant my spagnum and plants. I'm just seeking re-affirmation
on the wisdom of this. I feel that standing water leads to a collection
of toxins from decomposition, plant waste and stagnation that
circulation, and aeration within the reservoir with an aquarium air pump
to promote the aerobic breakdown of toxins and waste, will help keep the
water fresh and the spagnum healthy. I believe healthy spagnum usually
means healthy plants. I figure I'll perhaps get some crushed volcanic
rock to filter the water through and aerate the rock to give the
cleansing aerobic bacteria something to hang on to. In nature, bogs are
usually adjacent to streams and benefit from a little current there as
well as run-off from rainwater that potted plants don't enjoy and I am
hoping to mimic nature. By adjusting the height of the flexible drain
pipes I can regulate the depth of the water from 1/2 inch to full to
mimic wet and dry periods. I can also regulate the rate of circulation
from 1 to 4 gallons per hour. I could also put the pump on a timer and
circulate a little every day. Back in the good ol' days I had numerous
milk jug bottoms which were all but over-flowing with healthy spagnum
which I kept at least 3/4 full of water. As a result, my CP's were also
very happy. I'm hoping I can get that kind of success and better with a
recirculation system. It'll at least make it easier to water the plants
- I just keep the reservoir topped off. As soon as I get the system
assembled and working I'll post some pics. A trip to Walmart and $70
bucks of drip irrigation parts, pond pump and hose pretty much does the
trick. I'll probably have to vent the main drain hose that the smaller
drain hoses connect to in order to prevent a siphoning effect.
Suggestions and input is certainly welcome.

Hi Stephen,
I have been growing a number of the plants you mention for
several years. During that time, I have not attempted to
provide any sort of unusual compost. While I cannot
state with certainty that this is unimportant, I do believe
that it is not nearly as critical as one might at first
believe.
For example, I have grown N. burbidgeae from 1 CM seedlings to
near maturity in a 1:1:1 mix of peat, orchid bark and charcoal.
Similar results have been obtained with N. northiana, N. rajah, etc.
In short, I claim to be no authority, but my results suggest, at least
in the case of these species, that environmental conditions
and feeding are probably more important than any specific compost.
If you're curious about my results, I can send you some pictures.
Happy growing!

Dan,
Is your classroom air conditioned at night as well as during the day?
What about during the summer? I've known people to have good
success growing Darlingtonia indoors under lights in air conditioning.
But if they turn the ac down at night, that could be bad... Darlingtonia
are used to cool nights and warm days. I've had pretty good success
growing them outside here in hot and humid St. Louis by sinking the
whole pot in the lid of a large white styrofoam box, and keeping the
plant in mostly shade (a little early morning sun). Indoors, I would be
inclined to grow them under lights instead of the south window, but
that's just my guess. In nature, I've seen them out in the blazing full
sun, but they were rooted on a sheer cliff with constant cold water
running down around their roots.
Use a very well-drained media, even more so than for Sarracenia.
Straight live sphagnum moss works, or a combination of dried
sphagnum, perlite, a little peat and sand, etc. Also, I generally don't let
my Darlingtonia sit in stagnant water (they might like to sit in
constantly recirulated and aerated water, but not stagnant water).
Good luck!

Hi Paul and all,
Althought the flower stalks of Pinguicula do have retentive glands and
are able to capture insects, the stalks lack the separate unstalked
nonsticky digestive glands found on the leaf surface. Therefore, the
flower stalks cannot secrete any digestive fluid. The sticky glands on
the flower stalks are for deterring insects which might feed on the
flowers. Many noncarnivarous plants also have such sticky glands located
on their flower stalks for this purpose.

I grew mine inside in an apartment by a north facing window with
supplimental light from grow-lights with 14-16 hours of light during the
peak growing season. Normal comfortable air-conditioning day and night.
The compost was straight live spagnum and they were planted in milk jug
bottoms (a milk jug with the top cut off). I used rain water and when
the water level almost bottomed out I'd fill it back up to 3/4 full (3/4
up to the top of the spagnum). The Darlings loved it and even sent off a
whole mess of shoots that became new plants and very quickly over-grew
their modest bog. I'd feed the mature traps a baby cricket from the
local pet store, and occasionally a small roach (bachelor in an
apartment - there will definately be a roach or two...). If you use a
similar setup, one thing I'd do a little different in hindsite is
periodically drain all the water and give it a good flushing with fresh
rain-water to remove any buildup - even rainwater contains minute
amounts of salts that can build up after time. A laboratory water pump
like one from Edmund Scientifics could be used to flush it out. I'm
experimenting with a built in recirculation system that would eliminate
some of that work and make managing water levels and water quality much
easier. Make it a project for the students. IMHO, rain-water is better
for them than even distilled water. It's already acidified from
atmospheric nitrogen and probably has super-minute quantities of
nutrients picked up from the air that the spagnum finds palatable. I'd
run out to the water drain spout with a handfull of jugs every time it
rained. Now I've got a 35 gallon plastic trash-can that I've converted
into a sort of cistern. Keep a screen on it to limit mosquitoes - or
seal it back up after the storm.

hello barry and group,
so, the flames have come. what you say is fair enough barry, Except that
many issues of the cpn are out of print. i think that if i were offering to
sell (copies of) any color issue of the cpn for a substantial discount over
the back issue price, that would be truly reprehensible and actually
threaten the icps. however, given that many of the issues are not available
from the icps (including several from the 90's!), i don't think that
offering to trade a photocopy for a photocopy of (the entirely out of print)
ipsg journals has any real effect on the icps. i tried to buy back issues of
the ipsgn but that isn't possible; i'm assuming that whoever could trade
with me is in the same boat vis a vis the cpn. i also think that if
something is truly out of print, one is entitled to photocopy it in order to
have access to the info. i believe this is especially true of the cpn, since
very few libraries carry it. in sum--i encourage everyone to buy back issues
from the icps, but if they aren't available, i say it's okay to copy if you

It may be that I didn't give the plant enough water. This was my first
attempt with this plant. It grew in an 8" clay pot filled with equal
parts perlite, sand, lava rock, and vermiculite. I gave it a watering
schedule of 1/2 pint of water twice a week. This wasn't enough to drain
out the bottom of the pot but I felt this was ok since the plant is
supposed to be kept on the dry side, and having it drain would make the
soil very wet. The bad thing about the schedule was that while it was
constant, the weather wasn't - it got increasingly warm through March,
April and May. However, as the plant was declining in apparent health
(although the flowers looked great), it didn't show noticable
improvement after it was watered, as some plants in need of water do.
The reason I mentioned Peter's experience was that while
mine was limited to one dead plant, he said that his was
with 2 groups of plants in their first year. One of which
was left to flower and the other wasn't.

Hey Robert,
An internet subscription is an interesting idea, but I don't know of
anyone on the ICPS board or volunteers who are thinking about taking on
this kind of project yet.
Somewhat allied with this is our back-issue situation. Although I have
long been a big fan of keeping back issues in storage, the cost for doing
this is so great that it is barely a break-even prospect for us, while it
*does* cost a lot in volunteer effort.
So I've been looking more and more closely at the prospect of producing
our backs in CD ROM format. This would be much cheaper for us to do, I
think. It would also cost less in shipping and storage, and could be very
searchable.
Furthermore, we are actually running out of some of our back issues.
What will we do with the ones we still have, if we move to CD ROM? Compost
them, probably!
I'm taking off for a week, so don't expect another comment from me on this
for a bit. Later!

Subject: Utricularia article in Science News
Science News weekly magazine, vol. 159 for February 3, 2001
contains an brief article on bladderworts on page 69.
The article mentions the work of Jennifer H. Richards of Florida
International University in Miami. She proposes that there must be
some sort of symbiotic relationship between the plant and microbes
(e.g. photosynthetic algae, rotifers) in the traps. While the
plant may benefit from the presence of these microbes, it is not
clear how the microbes would benefit from living inside the
bladders. After examining the contents of 1,400 bladders under the
microscope, she discovered that insect larvae and other larger
creatures were found in only 6% of the bladders. She says that
although the bladders do absorb nutrients from prey, it is unlikely
that the rare prey could make up for the amoung of resource the
plant dedicates to producing the bladders. She calculates that, on
average, one quarter of the plant biomass is dedicated to bladders.
Her paper appears in the January issue of the American Journal of
Botany.
Also mentioned in this article is the work of Thomas Miller of
Florida State University in Tallahassee. He did research on
Sarracenia purpurea. He notes that this plant does not secrete any
flesh-eating enzymes within the trap, and in fact several insect
larvae survive only inside the pitchers. The plant seems to absorb
nutrients shed by the larvae.

Subject: Flaming Drosophyllum
Here are a few experiences I've had with drosophyllum... in my unheated
Glasshouse in Auckland NZ.
I grew my first plant from seed in a small pot in Autumn. When it was about
5cm high I tipped it out of the pot and removed most of the mix from the
roots.
A taproot descends from the plant about 6cm or so and then lateral roots
form.
I potted the plant in a mix of 80/20 pummice sand/peat in a 10L bucket sized
pot. The top 2cm was a layer of fine and coarse pummice.
The seedling survived this proceedure and rapidly grew to about 40cm across
by the time early summer arrived. It was stood in a shallow tray of water
all winter.
During mid summer it flowered profusely and then growth slowed dramatically
although it was beginning to sprout from almost every node. At this stage I
was only watering it from the top just as the leaves began to wilt.
A few months later it died. Luckily I had collected the seed.
I tossed the pot under the bench.
The following spring I had grown more from seed and ressurected the old pot
by cutting off the old stem and planting 2 seedlings in the pot. After a
while another shoot arose from under the surface (the previous plant had
come back from the dead)!!! - that's after about 8 months of being bone dry.
I left all 3 in the pot although each only grew to about 20cm across.
After they flowered and I collected the seed I decided to clean up the ring
of dead leaves by the only means I know how.
Thats right the pyromaniac voices in my head told me to set fire to them!
It was quite an intense conflagration and the label went all twisty.
Now I'm looking at 3 black stumps (1 has a green shoot still).
It'll be interesting to see what happens from here.
I've used the fire method before to clean up D. capensis. It worked well
with the plants becoming healthier and sprouting more too.

Dear Fernando & al.,

Not always (v.i.). While the morphological transformations (from a
simple leaf to a carnivorous pitcher) can be quite complex, the
physiological principle (secrete enzymes, wait, take up) is in fact
simple in comparison with snap traps.

OK (you wanted it!). All listeners not interested in details can skip
the rest of this message.
The morphological nature of the pitchers of all three pitcher plant
families (Nepenthaceae, Cephalotaceae, and Sarraceniaceae;
_Brocchinia_ and other cases not discussed here) is in fact
fundamentally different.
But let me first sketch the traditional morphological interpretation
of peltate leaves (leaves with the stalk attached some distance from
the leaf margin, usually on the lower leaf surface), so a few more
listeners will understand what I am going to talk about (all
botanists can skip this or comment it where I am wrong).
A normal leaf (the ancestor model) is a flattened structure attached
at the side of a shoot (the axis). It has two faces (surfaces) and
is therefore called a "bifacial" leaf. The face that originally
points into the same direction as the tip (apex) of the axis
(i.e. usually the upper surface) is called the adaxial surface. The
other surface is called abaxial (similar but different!). Both
surfaces are externally separated from each other by the
leaf margin.
While the vessels in the axis are usually concentric in cross-section
(xylem elements are located closer to the centre of the axis than
phloem elements), in the normal leaf this orientation is conserved
but because the leaf represents only a lateral outgrowth of a segment
of the axis, only the part of the vessels close to the point of
attachment of the leaf branches to form the vessels (veins) of the
leaf. The vessels of the midrib of a normal leaf have their xylem
thus oriented towards the adaxial surface and their phloem towards
the abaxial surface. The vessels branch only laterally (the normal
leaf is flat!), and the bifacial nature of the leaf is thus mirrored
in the bifacial orientation of the leaf vessels. The leaf vessels
ultimately terminate in the leaf tip (apex).
A normal leaf stalk (petiole) is a narrowed, elongated basal portion
of a leaf, and the vessels show the above mentioned bifacial
orientation even though the petiole may be perfectly round externally
(in these cases the margins can become entirely obscure). In a normal
leaf, the petiole is always attached to the very base of the
expanded, flattened part of the leaf (lamina), and the two leaf
margins form (at least theoretically) continuous lines beginning at
either side of the leaf base, running along the two lateral limits of
the petiole, circumscribing the lamina, and terminating in the apex,
where they meet.
What happens in the peltate leaf? Just consider the consequences if
the leaf margins decide to meet earlier, e.g. already at the base of
the leaf, on the adaxial surface of the originally bifacial petiole:
because they circumscribe/define the two leaf surfaces, the whole
surface of the petiole above the point of margin coalescence
(called a transversal zone, v.i.) becomes abaxial, and only a small
portion at the leaf base remains adaxial. Because the petiole now has
only one (abaxial) surface, it is called unifacial. True peltate
leaves always have unifacial petioles.
Because the orientation of the vessels follows the surfaces, they
form a concentric ring (with phloem elements pointing outwards) in
the unifacial part of the petiole (while usually a bifacial
orientation of the vessels can still be observed at the base of even
perfectly peltate leaves!). At the apical end of the petiole, the
margins reappear at a point called the transversal zone. This is a
part of tissue that may be rised adaxially above the plane of the
petiole. From this point the two margins first spread laterally to
turn upwards (considering the leaf apex as the top end of the leaf)
and to finally meet again at the leaf apex. The lamina surface
pointing towards the petiole is abaxial, and the surface pointing
away from it is adaxial. In the lamina, the vessels usually assume
their bifacial orientation (in relation to the two surfaces) again.
The degree of peltation (i.e. the relative distance of petiole
insertion from the margin) depends on the expansion of the
transversal zone.
The only carnivorous pitcher derived from a true peltate leaf is that
of _Cephalotus_. The pitcher leaf of _Cephalotus_ does indeed have a
long, unifacial petiole. Interestingly, the pitcher cavity is formed
mainly from the transversal zone, the pitcher lid is the apical
portion of the lamina, and the lamina margin forms both the peristome
and the lid margin. The wings are outgrowths of the abaxial leaf
surface. The inner pitcher and lid surfaces are adaxial.
The pitchers of Sarraceniaceae do have a peltate or nearly peltate
portion only at their very base. In _Sarracenia_ the transversal zone
at the basal, adaxial end of the leaf can be discerned as a small cap
sheating the axis. Above this cap, a short (a few mm long) unifacial
portion that represents the extremely reduced petiole separates the
leaf base from the lamina. The lamina is bifacial again. A minute
transversal zone at its base is almost indiscernible. The main
pitcher portion results from lateral fusion of the lamina margins,
i.e. *not* from peltation. The wing (two wings in _Heliamphora_) is
the fusion product of both margins. The inner pitcher surface (plus
the inner wing surfaces) are adaxial, the outer surfaces are all
abaxial. The lid is the leaf apex, the wing margin(s), peristome and
lid margins are the margins of the lamina. In effect, the transversal
zones in Sarraceniaceae neutralize each other, and the pitcher is
formed principally from a bifacial precursor, approaching what you
(Fernando) called "simple leaf folding".
_Nepenthes_ has the most complex organs among the pitchers because
it has in fact three distinct surfaces. It does not originate from
true peltation (although the leaf base is sometimes apparently
peltate): the petiole (in this case a tendril) is bifacial! The
pitcher is therefore not peltate (which would require that the entire
external pitcher surface is abaxial) but the ventral portion between
the wings (that correspond to the leaf margins) is adaxial, while the
larger (dorsal) portion of the external pitcher surface is abaxial.
The spur between lid and pitcher is the true leaf apex. The upper lid
surface is continuous with the ventral pitcher surface (as seen in
early stages of pitcher development), and is therefore a detached
part of the adaxial surface of the lamina. The peristome, the
interior pitcher surface, and the lower lid surface all originate
from "within" the bifacial leaf, and cannot easily be assigned to
either leaf surface. This is the "third" surface (neither adaxial nor
abaxial).

The morphology itself e.g. of a _Nepenthes_ pitcher is far more
complex and specialized than in the _Dionaea_ trap. The moving
tissues, electrical signal transduction, and perception of tactile
stimuli are also present in the _Drosera_ trap, the difference
is just a gradual one.

Well, there are also two mutually independent evolutionary origins of
moving traps (in Droseraceae and Lentibulariaceae), interestingly all
from *within* families that contain genera applying passive trapping
devices.

The mechanism of movement seems to be fundamentally different in
A & D. While _Aldrovanda_ apparently applies a fairly simple turgor
mechanism, the (still not entirely understood) mechanism of the
_Dionaea_ trap relies at least in part on growth.

This is the reason why all _Utricularia_ traps are so similar in all
fundamental morphological respects.

(...)

Right. Therefore in the unrooted "tree" above, the logical or
rather phylogenetic order could (by reduction) equally well have
been _Aldrovanda_-_Dionaea_-_Drosera_.
If we consider that e.g. _Nepenthes_ holds a systematic position
*between* _Drosophyllum_ and Droseraceae, the ancestral
Droseraceae trap does not necessarily need to have been of the
adhesive type!

David, please check with your legal counsel. It is permitted to copy
portions of articles. It is not permitted as you stated to copy an entire
article without written permission. I work for a government agency that has
a copying service for scientific articles. I use it constantly without any
fear of being sued so I think the law probably has some loop holes. My
guess is that if an article is being used by the copier for educational
purposes then copying the entire article is permitted as opposed to someone
copying an article for resale to make money.
I would hope, though, that ICPS would take a gentler approach with people
copying articles from past journals when the purpose is to educate
themselves. We've already heard that ICPS doesn't really make any (or much)
money from request for old material so I don't understand the stern remarks
made here, especially if the purpose is to educate oneself about cp's.
To take a stance that ICPS would sue someone for copying an article for
educational purposes is truly distasteful and I hope that you reconsider
your remarks.

Last year I germinated Drosophyllum seed that was at least three years
old. The seed case is very tough making this seed quite long lived. Make
sure you scratch or chip the seed in some way before sowing as this
makes germination take place considerably (i.e. months!) quicker. I rub

Dear Phil, Wayne and David,
Please keep in mind that it is David's job to ensure the integrity of
the CPN and any other materials published by ICPS. The idea is that
permission is granted before copies are made. The Copier should indeed seek
permission from the correct ICPS officials. What he (the Copier) has to do
(like pay dollars, maybe) for permission is what we ought to be debating.
ICPS members should be interested in unauthorized copying for trading
purposes.
I agree that when a copyrighted publication is no longer in print or
otherwise available from the publisher, the making of copies should be
allowed. However, the only legal way is to get permission from the
publisher, or use the educational loophole (which doesn't cover trading).
Some publishers have a more lenient policy, others are more strict. I hope
that there will be an easy and legal way to reprint books and magazines in
the future. Something like a book store, but that can actually print the
book for you when it's no longer in print...

Subject: copyright laws serve a purpose
Hi All!
To David: I agree, but I don't consider your words
'threatening' or 'flaming'.
I consider them to be informational and extremely
well-timed.
To everyone else: The first thing that came to mind
when I read that people wanted to copy CPN material
AND distribute it was: NO! Copyright infringement.
It is imperative that everyone stop and READ the laws
which govern our actions. David has a point that must
be taken seriously and with conscience. Today, our
children see so many UNETHICAL actions and it is the
teachers who bear the brunt of these impropriaties.
As a teacher I am NOT allowed to play c.d. music,
internet music, or videos in my classroom. This
violates copyright laws concerning "public"
presentations. We suffer reprecussions from our school
system when we are caught doing these things. We may
not copy published work from ANYWHERE, including the
internet! If we do, and distribute it to our classes,
our school system will not support our violation of
copyright laws if we have not first sought prior
approval from the writer or publisher. It truly
amazes me when educated and (usually) sane individuals
get these grandious ideas in their heads, voice them
to a population, and wonder why someone get's upset!
Think, speak, act... bear the brunt of your actions.
It is a natural outcome if you forget to think again
before you act....
If people are copying material (burning cd's and
photocopying.....) please keep this information to
yourselves! Don't be stupid and open yourself up to a
lawsuit that you will lose.... Please read about
NAPSTER for the most current example of copyright
infringement actions taken against someone who
'thought' he could do whatever he pleased with someone
else's product. I would hope this person 'thinks'
wiser next time....
If the publication does not allow photocopying, then
it can not be done. Period. End of ethics lesson 101.
BTW: For everyone who thought that David's reaction
was distasteful, it is equally distasteful to
challenge a very well-written and appropriate law.
Maybe it is time to consider publication of CPN's on
CD. It really wouldn't take much. Perhaps I could
look into one of my classes do such a thing. The
charges would include the price of the materials and
any licenses I would need to buy. We could count it as
one of our 'service-projects'... It wouldn't be an
ongoing thing, either. Classes and students change.
Therefore, it would be a pass-along project.

I'd like to leap on this bandwagon too, but I think we need to decide

How about a rule that the ICPS will enforce its legal rights over

personal use only, a copy of CPN which is no longer available through
the ICPS 2) where written permission for a copy has been obtained from

Hi Steve,
These symptoms sound like classic salt poisoning, also known as
mineral buildup in the soil. What's the plant potted in? Sphagnum?
How long ago was it last repotted? How do you know that the water
has not changed? Do you check your water periodically? I had an RO
unit that was giving me nothing better than tap water after a while,
because I did not maintain it properly. Even if the water is fairly low
in minerals, sphagnum will concentrate these minerals to levels
that are toxic to the plant after a period of time. The length of time
depends on how bad the water is, and your watering technique
among other variables.
Here's another sneaky cause of the symptoms you mention: styrofoam
peanuts that are NOT white. I used to use non-white styrofoam peanuts
in the bottom of my Nepenthes pots. The plants did great for months
until the roots grew down into the peanuts. At that point the plants
stopped
growing, and then began to show the leaf discoloration and distorted
growth that you described.
White styrofoam peanuts are okay.
I hope this helps.

Perry Malouf

I agree with what you say but...
Photocopying a few CPNs to distribute among friends or to exchange for
other materials is not in my opinion sufficient cause to start waving
heavy handed legal threats. As a member of the ICPS I would be extremely
uncomfortable with the society's funds being wasted in this way. There
are after all, far better ways to spend money.
I can also see things from the other viewpoint as well since I am editor
of the UK carnivorous plant society journal. As with the CPN all our
journal's material is copyrighted but I would never dream of using
copyright laws unless there was a clear case of profiteering from
copying our material. If for instance, one person was paying for a
subscription and then copying our material for other individual on a
regular basis we may consider action. Even so, I doubt that we would
consider bring the long arm of the law into the equation. Apart from the
cost I don't think it does the image of the society any credit.

well, as i have stirred up this mess, i guess i should make some final
comments, which will actually address multiple people's postings. to david:
gee whiz, do you really think that someone who gets a black and white copy
of an article from 1979 is going to later decide NOT to purchase a complete
cd-rom? whatever. the purpose of the icps is, in part, to disseminate info,
and i stand by my original claim that an out of print issue or article is
fair game (legal or not.
). you (and i once), were lucky to have access to the full set of cpn's at
berkeley's library, but the fact is that the number of libraries in the
world with such a set are very few in number, and also aren't going to send
them out through interlibrary loan. as it happens, a kind person in
australia is going to share his ipsg (to joe griffin: ipsg is the
international ping study group. and, incidentally, many issues ARE out of
print, but you'll only discover that AFTER ordering some volumes of the cpn.
no disrespect to the volounteers, all of whom i appreciate-- but that's how
it works.) journals without recompense, so you needn't worry about suing me
to recover the no doubt huge sums of money the icps might have lost. finally
david, i remember that a nice set of old sarracenia prints was auctioned off
at the convention this summer--am i mistaken, or weren't those photocopies?
i think that continuing this debate much further won't produce much profit
for anyone, but, i suppose it's my mess and i'll stay with it if necessary.

I'm starting back up pretty much from scratch into the CP world and as

don't think that'll go very far. I was wanting to use pure spagnum for
my CPs - namely Dionaea and Sarr and some Darlings - 100% live would get
very costly to ship. So I'm going to have to mix the media to make the
live spagnum go as far as I can make it. How fast does this stuff spread
- can I ever look forward to two pounds mixed with something else like
dried peet spreading enough to be able to use in other pots? The last
time I was doing this I had a few hap-hazard pots and milk jug bottoms
that grew spagnum fine, but never overgrew. Now I've got some larger
trays with a fledgling circulation system and hope to fill them up
without going broke paying for shipping and whatnot. With the fact that
live spagnum is the key ingredient in much of the compost we use to grow
our plants, it's surprising there's not more information on the care and
propogation of spagnum itself...

Are you suggesting that ICPS dollars will go toward sueing people that
photocopy the CPN? Or, are you just flexing your presidential arm? Either

Nothing like a good flame war, huh? The whole thing brings back fond
memories of the "Great Squirrel War of '00" and the "Finger Puppet War of
'99," where an enterprising 12 year old girl was driven from the list. I
haven't seen a single posting from her on this listserv since then, although
I've noticed her name occasionally on the Garden Web section for CPs. Good
riddance, I say! This is no place for a bunch of bratty kids!
Seriously, before we drive anyone else away from the listserv, can we just
let this drop? Don't violate copyright laws. If you do, keep it to
yourself. And by all means, don't solicit it on the listserv. And if you
don't like the way the ICPS is being run, volunteer to do it yourself next
time (no, I'm not an ICPS officer - I don't have the time!).

Subject: Re: ICPS Reprints, over-reaction, etc.
My own view on this stems from being an author.
I have come accross teachers who believe it is perfectly acceptable to
copy a single 1, 2 or 3 page section from one of my books, and
distribute photocopies to a whole class for educational purposes. This
is illegal and is a breach of my copyright.
I wrote all of my books to eduacate people. Money was never a motive. But the small amount of money my books earned
(and believe me, it was small) was a slight reward that went toward accounting for all my time and effort. Teachers, and
others, who copy material are usually doing so to avoid purchasing what is available. If the material can be borrowed from a
library or bought, then there is no excuse to justify copying. Certainly it is not a justification toi claim "education" as a motive.
Does anyone honestly think that Scientific American, Nature, etc,. would take kindly to whole journals, etc, being reprinted?
No.
One can not allow a section to be reprinted as there is no valid way to
disciminate between 1 page, 2 pages, 3 pages, etc. The law already
defines the number of words that can be copied, even by hand, to be
republished or distributed for profit. Legally, copying in order to
exchange a copy for something else would count as copying "for profit".
However, many publishers and authors do allow copies to be made within
reason. This is done with their agreement according to a very simple
process. In advance, one writes and asks permission to make the copy,
explaining why it is needed, how many copies will be made and when,
where and to whom they will be distributed. If the reasons are
acceptable, permission may follow. However, it is not unreasonable to
expect that attempting to make copies without permission will result in
athreat of legal action and refusal to allow copies even if they are
belatedly requested.
In my opinion, the ICPS response was not an overreaction. It was simply
a statement to give due warning that a breach of copyright had been
suggested and that, were it to go ahead, ICPS would reserve the right to
protect their asset. By stating this fact, and by explaining the
copyright, no-one can proceed and claim ignorance. had the response
been less direct, it could have been open to misinterpretation or even
have inadvertently waived copyright.
In addition, ICPS is likely to protect its copyright for nother reason.
Authors who contribute may well maintain copyright of their
contributions while allowing (obviously) ICPS to print the
contributions. (As an author, I routinely apply copyright to all
material I publsih, no matter where it is published.) If ICPS then
ignores attempted breach of copyright of their journal, may contributors
may reluctantly stop contributing and send their copyright material to
others who will protect the asset more stringently.
I am not suggesting nor implying that anyone intended, in this case, to
breach copyright, make a profit from someone else's asset, or do
anything else immoral, improper or illegal. But I take this opportunity
to publicly applaud and support the response from ICPS on behalf of all
those who contribute their time and effort to publishing original
material. ICPS should and did act in the interests of its membership by
protecting copyright of material it published.
As someone else rightly said, there are a few exceptions that allow copies to be made (e.g. in the UK, a student can make a
personal copy of material for study, but not to share with others or to republish in part or as a whole). But one has to sign a
document to declare that the intention is legal and will not breach copyright.
And in case it's still not clear, I'll repeat what I said the last time
this subject arose. If anyone copies material that is copyright of
someone else and does not have prior consent, and if such copies are not
permitted by law, then the making of those copies is theft. The
equivalent is that I enter their greenhouse and help myself to cuttings
of their plants, without permission. It';s a funny thing - but many
people think its OK to steal someone else's property (NAPSTER users,
teachers who photocopy, PC users with unlicensed software, etc.), but
those same people never seem to like it when I suggest I'd like to take
something of theirs. And they always lock their doors when the leave
their house. Fair? I don't think so!

Phil and all,
I've tried slicing the seed case a number of times and found that the seed
doesn't germinate. Wether I sliced too much off or sliced something vital I
don't know.
I've found that the best way,like yourself, is to rub the seed coat with
sandpaper and submerge in water for 24 hrs.
One thread that seems to come thru in the latest discussion is the plant
dies (or at least becomes weakened )after flowering. Have other listserve

Subject: Re: Spagnum...
Hi Mike and All,
Regarding the cultivation of live Sphagnum, I'd recommend chopping up the
live stuff in to 1/2 " pieces and then pressing it down into pots filled
with 'wet' peat moss, with the soil level being about 3" from the top of the
pot. This will give it plenty of room to grow as well as help maintain a
more humid environment. It spreads very quickly in the spring and summer if
it is kept fairly cool and protected from the wind. I've grown Sphagnum in
almost every imaginable container from a granite indian grinding bowl, to
those terra cota clay strawberry pots you see at chain stores in the spring.
Those plastic blue 'toddler wading pools' they sell in the spring also make
for good Sphagnum cultivation if you fill it up with wet peat moss/perlite &
then wrap wire covered with 4 or 6 mil poly around it after you've
pressed your pieces of live sphagnum into the surface layer. (In
fact, what I just described makes an excellent and "cheap" CP
greenhouse for those with understanding wives & neighbors.)
Might want to drill a few holes at the very bottom of these plastic
pools (and have a 3" layer of rock at the bottom) so they can drain
and be flushed out periodically. Once it gets established, this stuff pretty
much takes care of itself as long as you remember the cardinal rule of
pouring fresh water through it on especially during the hot summer months.
This is what works for me anyway. Hope this helps out and good luck.

Dear Joe,
P. gigantea is not really that different from commonly cultivated Mexican
Pinguicula in its growing requirements, I think, and as already stated on
this list recently, its growing requirements are very similar to P. agnata.
One thing is that it requires more air humidity than any other Mexican
Pinguicula because it has glands on both sides of its leaves and thus
dehygrates faster when the air is dryer. But even P. agnata will do better
with higher humidity in the air. But be careful, higher humidity in the air
does not mean more water in the soil. This species also stands high summer
temperatures.
I see nothing wrong with your potting mix. I personally add some choalk to
mine (5%) to keep in check a pathogenic fungus called Pythium which eats up
the center of the rosette mostly in early spring and to which Mexican
Pinguicula seem sensitive.
Keep on trying, it is a nice plant,

If you had a mess of live spagnum, would you still use dead spagnum as
an under-layer? Some spagnum grows in cedar forests - what mileage have
you guys had with using dead cedar or pine needles as an under-layer?
Can the spagnum survive and flourish sans an under-layer altogether? All
this is assuming all other things are equal like light, rain-water,
temperature, etc...
For reference - My little bog is in a West facing window over which an
awning hangs, so it only gets a couple or three hours of direct sunlight
a day, with the rest of the day bright and indirect. Since it's inside,
it's also air-conditioned. I plan on circulating rain-water through the
compost either continuously or periodically - experimentation is in
order for the best pattern there. I also plan to experiment with
periodically flooding and then draining the spagnum over periods lasting
perhaps a few days each (I'll just rotate the alligator-clip that closes
off the bottom drain amongst my containers). I've just spent some money
that, well, leaves things tight here, so I want to make sure I get all
the recommendations in to protect the investment and get things on the
right foot. Those plants are expensive...

First of all thanks, David, for safeguarding the interests of the
ICPS and of CPN in a clear and easily comprehensible way. I had the
privilege of personally meeting our President in San Francisco, and I
trust he did not want to threaten anyone by unjustified legal action.
What he expressed is just an appropriate description of the law "as

Hooray! Thanks, John.
If you (anyone) have further questions regarding CPN (require a
permit?), why not ask an editor (or both)! I am quite confident it
would give everyone a better feeling if he/she knew that what he/she
is doing is legal.
If a given CPN issue of interest is still available from the ICPS
(again, an editor could help to find this out), buy it. It is IMO
not expensive (just compare it with any similar publication), it
is perfectly legal, and you get the real thing, not just a lousy
photocopy (at least after vol.5).

I have forgotten to mention (but the message was very long already!)
that this is one of several discussed interpretations of the
_Nepenthes_ tendril. It is the interpretation I (and several
others) tend to adopt. The leafy portion at the base of the tendril
is under these circumstances regarded as the expanded leaf base, or
(in order to homologize it to organs of related plants) as +/- fused
stipules. The leaf base is indeed a part of the petiole.

I have looked very closely for insects (because of the distorted new growth)

problem. I have not changed anything in regard to the location, water, or
temp. I have had this plant for quite awhile, and it has always thrived. I
don't want to loose it. Any ideas?
-------------------------------------
Well, I had a few Good suggestions. I am a stickler about checking my water
alkalinity and soil EC, so I don't think salts are the problem, I do like to
let my Nepenthes dry just slightly (not too dry) between good heavy
waterings, I have quite a few Nepenthes and they grow very well, I have
found what works for me. I think the media is breaking down to much, and
this plant needs to be repotted. This is also what was suggested by several
respondents, and it makes sense. It is a little frustrating because this is
my biggest bicalc, and I LOVE IT. It is old and wise. I worry a little about
repotting because it does not have any basal rosettes, it has only one fat

straight for NAPSTER and similar sites sites. Why? Because they were

illegally copy music. Here's the bottom line:
Musicians often depend on money from sales of their music in order to
survive. It's a job for them, not just a hobby. They have to generate
income to pay their bills. By copying their music illegally (downloading
from NAPSTER, copying a CD from a friend, etc), you are preventing them from
making a living. How would you like it if someone came by on payday and
snatched your check? What would you do? Well, for musicians, if they can't
make enough money from their music, they've got to quit doing music

I would echo what Perry said. Since you see no problem with bugs on the
leaves and your environment has not changed I would suspect something is
going on below the soil. It is always frightening to take an ailing
plant and disturb its root system but sometimes it just has to be done.
If the plant is not too far gone to take some cuttings you might want to
do that soon.
Good luck,

Hi Jan and all,
Thankyou Jan for your thesis on pitcher development. I wish you could
have added sketches to make it all more clear. I can understand how the
trap in Sarracenia originally developed, this seems quite simple.
Cephalotus is more complex and I'm not sure I understand this, but I

was a real puzzler to me until just recently David O. Gray told me of his
theory. I feel sure he has figured it out. YOU-WHOO, David! Please write

>>The mechanism of movement seems to be fundamentally different in
A & D. While _Aldrovanda_ apparently applies a fairly simple turgor
mechanism, the (still not entirely understood) mechanism of the
_Dionaea_ trap relies at least in part on growth.
Jan
I have been growing Aldrovanda and Dionaea and comparing the trap
closure. In Aldrovanda there is a primary snapping closure followed by a
slower secondary sealing, as also seen in Dionaea. I think the primary
snapping closure of Aldrovanda only appears different in motion because
of folding action, but I do not believe the mechanics behind the closure
is fundamentally different. This is but another feature (such as style
movement) not discernable in herbarium material:-)

Subject: Re : Drosera Snap Traps?
from CP Digest 2456:
>>Ok, so sundews are hardly the speediest of trappers when furling their
leaves around prey, but has anyone experimented to find out how many
glands must get excited before furling starts? Have Droseras developed
a redundancy mechanism like Dionaeas?

Hi Nigel and all,
Brilliant Nigel! I see what you mean! In Dionaea, one trigger hair must
be stimulated twice, or two hairs must be touched in quick succession in
order for the trap to close. This is to prevent a trap from closing
unneccessarily and waste energy on some inert object. I can see how the
redundancy measures of the sundew could have evolved into that of the
flytrap. Laurent Lagendre gave a most excellent presentation on flytrap
versus sundew trap workings at the CP World Conference 2000, but I do not
recall him bringing this particular item up.
After writing the above I did some experimenting on my Drosera
burmannii. You probably already know that several tickles to the tentacle
starts the movement. But I think I have just discovered something new as
well. I tapped on only the tentacle stalk and nothing happens. Later, I
tapped on the gland at the tentacle's end and this starts the tentacles
movement. This made me realize something. Microscopic examination of
Dionaea's trigger hairs reveals that it is composed of two parts; a long
spike on a pivoting base. The sundew tentacle is also composed of two
parts; the retentive gland and the tentacle stalk. When the gland tip of
the tentacle is touched, the joining point of the tentacle stalk pivots.
This pivoting action seems to stimulate tentacle movement. Think about
that. This is more evidance that the trigger hair in Dionaea is a
modified sundew tentacle.

Well, of course that must be the "Malaysian Death Plant!"
"Dionea malaysiensis" if I'm not mistaken. ;-)))

I've not had this happen to any of my plants. What usually kills mine is
not being able to get the soil completely dry before the onset of
winter. With our weather this seem vital since otherwise the plants
simply rot.
I do know that once flowering the main stem of the plant dies but it
should usually regenerate from side shoots further down the plant.

Hi Jay. This is probaqbly not the answer you were seeking hut what the heck!
I'm not going to refer directly to CITES rules. I am going to refer to
the Biodiversity Conventions (BC's, as I can't be bothered retyping so
much!).
The BC's dictate that all signatory countries (and all the important
countries have signed, especially those with interesting plants) reserve
the absolute rights connected with the flora and fauna (all
biodiversity) within their borders. (It's a bit like putting a
copyright on your plants to prevent others making profit from what's not
theirs - touchy subject!!!) By absolute rights, the BC's give undisputed
ownership of all rights to the country of origin of the living organism.
Ownership of all rights covers not just the whole plants, but seeds and
any part of the plant. Far less known is that information is also
protected, so if you visit a plant in the wild and discover a new fact
anbout it, that fact is protected and the country in which the habitat
exists (where you saw what was new) has a right to control when, where
and how the new fact is published or if it is published at all. They
also have full rights to any benefits that accrue from publsihing
information or from any plant (whole or part thereof) or seeds that are
distributed. People are amazed by the protection of information but
actually this is a primary part of the BC's. For example, if a drug
company finds an endemic plant in the Brazilian jungle and determines
that the plant contains a useful drug, then Brazil owns that information
- the rule is designed to prevent large companies making commercial
profits from information about plants found in third world countries.
What all this means, as far as your question is concerned, is that the
BC's dictate that seed taken from a wild plant (or from material that
can be shown to have originated as a wild plant) can not be distributed
without the permission of the country of origin of the wild material.
So, for example, if someone visits Borneo and finds a new Nepenthes
species: First - publication of the new species requires the permission
from an appropriate agency within Borneo, Second - any plant material
removed, including seed, must be accompanied by permission from such an
agency. Ignore either rule and the material or information is
effectively illegally obtained. As soon as that is true, CITES or
Customs can confiscate the material. If someone collectes plants or
seeds, grows them, collects new seeds and then distributes those seeds,
they are still stolen property and technically belong to the country
where the wild material originated.
Exactly how anyone can determine that seeds originate from a wild plant
is a mystery and a clear loophole for those intending to flout the BC's
and local laws within countries.
I think I've got this right. The best person to tell othrwise is Mad
(if you see what I mean), and she'll no doubt corect me if I am wrong.
But as often as I've written this, no-one has said I am in error.

Paul

Silly boy - you should ask it for permission to force it to bloom before

Very interesting! Does this mean that Droseras respond only to movement? I
don't know where I got the idea, but I always thought that they also
responded to taste (for lack of a better word). In other words, I thought
that the gland could sense that there was something edible sticking to it (I
hope this is making sense?!?) as opposed to a grain of sand or dead leaf or
something. Maybe what I need is a brief lesson in the anatomy of a sundew
leaf.

Dear John,
> Very interesting! Does this mean that Droseras respond only to movement.
No. Both _Dionaea_ and _Drosera_ have species that respond to both
movement and taste.
This the one of the things that subcarnivores don't do--taste their prey.
The Drosera seem to rely on taste more than Dionaea to activate a trap, but
perhaps we are not seeing the whole picture and movement is also part of it.
Whereas Dionaea use taste to keep the trap shut...

Hi all,
It must have been late when I typed this posting. Either that or the
senility is coming on sooner than I expected...:-)
The below should have read "Mexican Cacti seed originating from Mexico".
Where the reference to Canada came from I have no idea!
Sorry for any confusion caused, especially to Canadian Cacti growers on
the list. :-)

This is from the horses mouth so to speak.... A few months ago I emailed
Ger Van Vliet from CITES on this issue.
His reply was that there are no controls on the international trade in
App II seed with the exception of Mexican Cacti seeds originating from
Canada. Seeds from App I are restricted under the convention.
If you want to see the original mail drop me a personal mail and I will
forward a copy of his email.

Subject: Mealworms...
Has anyone used mealworms as plantfood? My local petstore has tons of
them and has shown me how to maintain a virtually inexhaustable supply
of them. They are larvae that eat meal and potatoes, pupate and produce
little black beetles that quickly mate and create the next generation. I
don't see a problem with a pitcher style plant - they should drown like
any other bug, but I wonder if a VFT would be able to handle one...
Cheers,
Mike
