Earl: I am not too sure about growing Nepenthes outside. You would be best to experiment with extras. Are your Nepenthes doing alright in the greenhouse? They can take stifling hot humid conditions better than any other cp, in fact most require it. Otherwise, I bet you could grow just about every other cp sp. outside. Don't worry about the humidity being too low outdoors. If I can grow cp outdoors in Arizona, you should have no problem! Just set the pots in a tray of water, and try to work them up into full sun. Avoid too quick a transition to the sun, But try to get them as much ligt as possible. Most sp. have their best color in good light. I have had the best luck with Drosera outside. Ordinarily, the common Drosera are very easy to grow. My guess is that your greenhouse envioronment was responsible for your loss of this genus. I grow Drosera in a greenhouse in AZ, but this g-house is heavily air-conditioned. It is kept pretty cool and and very dry.

(sniff) :-) Well, as I said, I'm back from the holiday excursions and useless observing trip to a rainy mountain. No science done. My mailbag was quite full! In my off hours on the mountain I brought my tool chest and took advantage of the relatively mild temperatures in Tucson by ripping out the electrical system in the Greenhouse and rewiring it with a much better thermostat. I figured out a way to use a single thermostat to A)power the heater if it gets too cold B)Power my cooler at low speed if it gets too hot C)Power my cooler at high speed if it gets even hotter I am pleased with myself. I notice that with the onset of cooler weather I'm starting to get some flowering in my Utricularias. Namely, the livida that I have from Gordon and Rob are flowering, and the graminifolia from Rob is producing inflorescences as well. This is the plant that we thought was reticulata for a while. The plant that Paul McMillan has that HE thought might have been reticulata is going to flower as well...possibly more graminifolia? Paul got his "reticulata" long ago from WIP, and I bet that that's where Rob's clone originally came from (so many trades ago). My B. gigantea continues to grow, as does my D. regia. The B. liniflora `Kununurra' that I grew from seed from Allen is about to flower, and I can say that it is noticeably different from the liniflora clones that are commonly in cultivation. The plant is a little taller, by about 30%, but the internodal distance is greater, so the plant has a lankier look (although it is robust). The stem is also rather reddish, producing an interesting colour contrast. I haven't caught it in flower yet. I'll keep you posted on flower morphology and seed production. The seed production on my D. indica is good. I have decided that this is a very nice plant if you can get it to flowering size. It needs a big pot, though, as it topples over early on (and that is in full sun). I talked to Gordon Snelling last night. He verifies what Michael said, i.e. he's doing alright in spite of the freezes he's been having. He said that it did set his D. petiolaris `Kununurra' back a bit. Well, that's all for now.

I haven't got any seeds because I nip off their flower buds as they form, but I am sure that plants or root cuttings would survive the trip. It is probably the easiest Drosera species to grow. There is no dormancy period. The Hawaiian native CP that you have is, I think, a tropical form of D. intermedia. This plant is common in the eastern US, where it forms hibernacula (winter resting buds) during the cold season. If I remember, your intermedia either does not form such buds, or it grows as an annual. I have recently gotten an intermedia `Cuba' from Rob, and am curious to see if it produces such a winter bud. Anyway, it is possible that your intermedia just died its normal death as it tried to get ready for winter hibernation but was forced (by warm conditions) to continue to grow. Who knows how long that species has been in Hawaii, trying to adapt (rhetorical question)? You probably were trying to grow a plant that is just barely hanging in there in the first place! >My U. livida is pumping up flowers.

I would really like to get mine growing an a northern Hemisphere cycle. I think I will try an experiment on one of the less desirable tubers. Giberellin is a plant hormone which can be used to break dormancy in seed and other under- ground plant organs. I will see if a little giberellin dip might get one of these tubers growing. Barry: you wanted to keep yours dormant by planting them and keeping them warm? My uneducated guess would be that if you want to keep them dormant, keep them right in the bag. As soon as you bury those puppies they will be exposed to every kind of fungus, bacteria, virus, slime mold, insects, protists, and alga which breed in the dirt. Plant them if they start to grow in the bag. I would also say, keep them cool rather than warm. They are trying to ride out the hot Australian summer, but the tubers are cool and deep down under (the soil). My big question is: what triggers the end of dormancy. Is it an internal (hormonal) or enviromental (temp, moisture) signal??? Barry, if you are writ- ing Lowrie again I would ask him everything about dealing with dormancy.

If I were planning a US trip to go CPing, I think I'd either head to the South Carolina area, or to the Mobile Bay area. First thing I'd do is call Bruce Bednar or O. Clyde Bramblett and ask the m what they think. They do a lot of bogging down there. Best thing is to get some local expertise. I've discovered, from my own goofing around, that you can get to just a few hundred feet of prime CP territory and not know it. Another route is to plop down in prime CP territory (like South Carolina) and blow a day in the herbarium researching recent collections. That's what I've done and it work s pretty well. I got some seeds of those Nepenthes you mentioned from the seed bank, and am trying to get them going. I tried Mike's method of putting them in a pot of soil in a baggie that was microwaved (introducing seeds AFTER the microwaves) but I think that the seeds are getting killed by fungus. Last time I listen to Mike! :) Well, I finally got to look through this Peter Taylor double issue of CPN. I have a couple of comments, since I seem to have been given the title of Utricularia fiend... I think that the treatment of the N. American Utrics is great, with two keys to ID your plants. Also the notes on each species are great, with ranges for the plants (which makes up for the lack of range maps). It's also very nice for the CP-horticulturist that he includes information which is the closest he ever gets to growing instructions, like ``....habitat is wet sand or peat or in shallow water....'' That he included this info, which is very sparse in his monograph, is probably because of prodding from Don Schnell who always suggests I include this kind of information in the stuff I've written for the mag. Usually a clear writer, Taylor makes a goof on his description of U. juncea (p17-18) when it sounds like he's saying a cleistogamous form of U. juncea is validly called U. virgatula. The rest of the Utricularia stuff is just derivative of his monograph. So, it's mighty useful if you don't have the 40 pounds to shell out for the book, but since I've got it most of the CPN issue is just redundant. I'm particularly happy that they've printed the list of invalid names, so people can correct their tags of U. racemosa, capensis, etc etc. The photos of interesting species, especially the ones with antennae-bearing flowers (which are thought to be pollinated by flies), I found very welcome. BUT THE BIGGEST AND BEST THING ABOUT THIS ISSUE WITHOUT A DOUBT IN MY MIND is the treatment of Genlisea. Here we have a first, complete key to the genus. Hurrah! A very short description of each species, and a bibliography! What a great thing to have. I'd eagerly buy those pages alone for more than I'd like to admit! I am psyched! Anyone going to send off for the 1991 World CP list? I think I might... especially since this Jan Schlauer claims there are references for each plant. This is a way to finally get some data on the ancient D. communis/ burkeana/spathulata/capillaris problem and so on. OK, this is great.... The other day I was getting entirely fed up with the mats of algae that I get floating in my trough of U. resupinata. Utricularia resupinata is a species that grows in peat/sand about an inch or so submerged by water---it looks like grassy blades growing out of the substrate, waving in the water. So anyway, I was looking at my grassy blades getting choked by a thick mat of green algae, when I had an idea. I got a sturdy metal comb I use for brushing out the coat of my golden retriever/lab mix, and ``combed'' the plants. The result? All the algae got strained out and the Utrics stayed behind unaffected (except for a quite dashing, well coiffed look). I think any coarse comb would work great for this. I wouldn't suggest it for most free floating aquatics, though. Not high tech, not low tech, but just the right tech. ################### From: s883351@minyos.xx.rmit.OZ.AU (John Taylor [The Banshee]) Date: Wed, 4 Sep 91 12:20:03 +1000 Subject: re: Utrics >I have a U. calycifida in flower right now.

Not on your list, my D. cistiflora `Red' and pauciflora `yellow' are doing well, the latter big enough perhaps to flower. But the name pauci-flora means either few-flowers on a scape, or maybe the plant rarely flowers... Incidentally, both petiolaris `Kununurra' I got from Allen were from live plant shipments, but I lost my falconeri from him. I think I'll try seed some time, especially with that handy heating info. My D. regia seems to be doing well. I encountered the same strange losses that you mention. I think that you just have to have some luck to get the plant past that phase.

'Twas a nice sunny weekend (for once), so Paul and I jumped in the Moke and had a quick walk around the Langwarrin Flora and Fauna Reserve. Polypomphlyx tenalla plants are out and in flower (most were almost ready to open - should be a good display in the next week or so - with a few fully opened). Drosera peltata and auriculata (maybe) plants are gettimnghng a bit taller (a few inches now) and some peltatas are flowering at this height.

Not that this will come as any great surprise to most of you, but I'm amazed at how sensitive the Queensland sundews (adelae, schizandra, prolifera) are to light. If my prolifera gets even an hour or so of direct sunlight, its' growth slows way down. However, with 75% shade cloth over it, it rolls out a new leaf at the rate of one every 5 days or so. Same thing with my adelae. (I don't have a schizandra :-( ). I've heard that they are sensitive to heat, but it seems that sunlight, and of course possibly the heat generated in the leaves by the sunlight, may be a more telling factor. Since Peter Damato grows his schizandra in the HOT area in his greenhouse, with his lowland Nepenthes, I'm inclined to believe that it is light/light-generated-heat, not ambient temp, which affects these species the most. As soon as the little plantlets are big enough, I'm going to transplant one into my 80 degree terrarium and see how it does in there under lights. BTW, some live spahgnum I have in the terrarium got molded over with grey, fuzzy, stuff. I presume this is a result of not enough ventilation, right? But if ventilate more, the temps and humidity go down. Any suggestions? Perhaps keep the moss more wet? ################### From: Robert.Allen@Eng.Sun.COM (Robert Allen) Date: Mon, 9 Sep 91 15:16:04 +1000 Subject: peat planting mixtures.

He said it works just as good as peat sand, and the pots are a lot lighter. I tried it, and it seems to be a good deal. Put a later of straight peat on top though to keep the perlite from floating if you water fro above.

In addition to the Nepenthes, CP on display included some common drosera and sarracenia and some large dionaea.

While waiting for my seed bank order to arrive I've been thinking about how to germinate what I've ordered. I've decided to place all the seeds in damp, milled, spahgnum, either in pots, or in little six pack containers. The problem is, I want the containers to be within a few inches of the lights, and the Nepenthes in there are too tall for that. The solution? I have some plastic grid sitting in the bottom of the acquarium so I can keep about 1/2" of water in there and not have the Nepenthes sitting in water. What I'm going to do is to cut a piece of the grid off, then raise that portion alone up to the lights, using plastic pots to block it up. I'll have a split level terrarium. Of course, some of you have probably already figured this out, but I was sort of pleased with myself for making the most of my limited space.

I count 6 D.peltata seedlings just sprouting from a pot I sowed last April. I almost gave up hope for them. I'm harvesting seeds now from the D. indica I sowed at the same time. When I used to grow D.peltata, I remember that they flower during the first year, so it's possible to grow them as annuals if you don't want the hassle of taking care of them as they go into and out of dormancy. Does anybody know of other easy-to-grow tuberous Drosera other than auriculata and peltata that will flower during the first year? I also ordered more Nep seeds from the seed bank. They should be arriving any day now. Is anyone growing N. x dyeriana? This seems to be the Nep with the largest pitchers of the common types that are grown. The species N. rajah is the one that is most often noted as having the largest pitchers, but I've also read somewhere that N. merrilliana holds that distinction. Maybe there's a different criterion (e.g. one is "tallest", the other "contains the most area in cubic units"). Longwood Gardens, by the way, is supposed to contain the best Nepenthes collection in the USA, at least according to an old CPN - March 1979. The best in the world is supposed to be at Edinburgh's Royal Botanic Gardens. The curator at Longwood is (was) Pat Nutt. Another CPN said there are private greenhouses at Longwood that ICPS members can see if they announce their interest. What kind of species/hybrids of Neps does everyone grow? I might have a few cuttings of N. x curtisii (?) to trade. This plant was originally labelled as "N. x superba". The plant doesn't look anything like either of the two parents listed in the World CP List. This is probably the plant "N. curtisii" mentioned in CPN 1987-p.69. It has a wide peristome and looks a little like N. maxima. The true maxima I've read is supposed to have a glandular crest, but my plant doesn't have one. It may be N. x mixta "superba" though. It produces rather big pitchers - around 8 inches! Other Neps I have - N. tobaica, N. anamensis (both are small - about the size of year old seedlings), N. gracilis, N. khasiana (Michael sent me a cutting of this), N. ampullaria (green), N. ampullaria (red) (I got the "red" variety from Barry - both are too small for cuttings), N. x rokko (I got this from Barry too - still reviving after being slow to root), I HAD alata (boschiana mimic) from Barry but it croaked before rooting, N. gracilis x hookeriana (may have enough for a cutting - fast growing - pitcher not too exciting), N. x hookeriana (?) (got this from Michael, haven't seen a pitcher yet), N. x boissiense rubra (maybe lecouflei), N. x wrigleyana (kosobe) - (originally labelled x kosobe, looks like wrigleyana, nice completely red pitchers, looks like pic on p. 86, Sept 87 CPN - fig 5), N. x balfouriana (doesn't produce a lot of pitchers, may have enough for a cutting, creamy-colored pitchers w/ not very wide peristome, sort of ordinary looking). Has anyone germinated the N. ventricosa hybrids from the seed exchange yet? Anyone interested in orchids too? I have a duplicate Slc. Empress of Mercury "Gwo Luen" AM/AOS I can trade. About D. collinsiae, it may still be a hybrid even if seed is fertile. If the embryo is an amphiploid (where the two sets of chromosomes from the two parents don't synapse), the resulting plant may produce viable seeds. This is according to a CPN from 1990. The article was about Drosera evolution. I got a couple D. collinsiae from Michael too. My plants produce leaves at a 45-degree angle, like D. intermedia. The leaves look like intermedia, but the petioles seem to be a little longer. Rob M.: Did Barry say you sent him a message about a CP field trip? Could you put me in your CP mailing list? I didn't get that message. My address is "dngess01%vlsi.louisville.edu@ulkyvx.bitnet". Barry, sorry to hear your D. falconerii died. Did your D. arcturi ever germinate? What kind of things does Don Schnell grow? There used to be a big list put out by Bob Ziemer that listed all the different species that people grew, and noting those species people had to trade. I remember Don was a big Nepenthes grower; and, of course, being an expert on Sarracenia, had a ton of these too. It was sort of surprising to see that he didn't have any tuberous Drosera, not even a peltata or auriculata. ################### From: ATLAS@JHUVMS.BITNET Date: Wed, 11 Sep 91 08:44:26 +1000 Subject: stuff Regarding the mosquito larvae, I have the same problem as Earl.

A marvelous thing occurred this morning: the muses of organic chemistry granted me some precious time away from the chemicals and synthetic manipulations for a morning. A great opportunity to catch up on the triple digit emails bursting from my Newmail Folder! I spent about four days up in and around our capital city, Ottawa, on both business and pleasure. The last day was reserved for a pilgrimage to D. linearis country along the shores of Lake Huron near the famed Bruce Penninsula. Braving the swarms of horseflies (whose bite is not noticed until a few minutes AFTER it has dined) while travelling up the eastern shoreline of Dorcas Bay Nature Reserve, I arrived at one remote station just a hundred feet or so from the lake water. The area - about 30 sq. feet - is supported by run-off from lime- stone-based forest of the interior. Here D. linearis was growing in abundance (about 500 plants) along side with P. vulgaris and a few S. purpurea ssp. purpurea f. ripicola in full sun. Plants were about 1-2 inches high and blood-red and most had already commenced hibernaculum formation (Date=AUgust 12). An interesting observation is that the linear leaf sundew only seems to grow in locations that receive at least 5 hours/day of direct, unobstructed sunlight and the previously-reported observations of its intolerance to plant competitions certainly seems to hold. Also, very, very few plants seem to grow in moist but well-drained areas, preferring wet substrate with a H2O table about an inch or so below the soil surface. Two other stations were visited, one of which was fenced off private land purchased in 1962 by the Federation of Ontario Naturalists (FON). Growing conditions were very much the same as for the first station, except that the plants were growing in pure sand. Here I also found U. intermedia in full flower, their huge canary yellow corrolas resembling the U. juncea ones illustrated in Don Schnell's book. Further detective work around a dried up lagoon area of the reserve turned up thousands of the ripicola form of S. purpurea in a 1 acre flat location. In a bushy area by a small stream next to the purps revealed a good sized colony of P. vulgaris growing in almost full shade (in contrast to the full sun location at the first D. linearis station). I was hoping to see (well, not really) Eastern Canada's only poisonous reptile, the infamous Massasauga rattler. The Dorcas Bay area is one of about 2 or 3 small areas in Eastern Canada where the rattler can be found. At another D. linearis location at Petrol Point (about 50 km south from the Dorcas Bay Reserve, see CPN article on D. linearis by Don Schnell, ca early to mid 1980's), the sundews are on average 1 inch larger than their Dorcas Bay counterparts. It is not know whether this is genetically or environmentally determined but by next summer I should have an idea from growth observations of my 1 yr. old seedlings. The Petrol Point area is fortunately a reserve, also bought out by FON, to protect the last reminants of prime habitats of unique Lake Huron fauna and flora from development (primarily cottages). I'm happy to report that over the past 4 yearly visits to these areas the D. linearis populations are strong in both quality and quantity, with possible exception to the Petrol Point reserve where numbers have dwindled somewhat. This summer, D. linearis was officially recognized by the Canadian government as an Endangered Species. Well, its about time! I heard from Gordon about a week ago via post. He sent me some of the Nepenthes seed that everyone has been mumbling about. I sowed them on pure milled Sphagnum the day I received them and popped them in a Ziploc bag under lights. So far nothing but at least no signs of fungus. I dislike peat mixes for Nepenthes seed since they tend to entice fungal growth in my experience. Gordon also sent me many months ago some of those N. ventricosa hybrid seed but after about 8 months at least, I have yet to see a peep from them. Gordon said to hang on to them since a few grower have reported germination: for some reason, these particular seed insists on taking their cool time. Barry, regarding trading with Fred Howell, I can surely back up Paul's claim that he's a very fair trader. In fact, he's sent me more plants than I deserve (and feeling a wee guilty I might add)! Have noted D. pygmaea contamination in D. manniana and D. spilos gemmae received from him and some tubers are not well labelled. It does add a certain thrill of adventure and the unexpected in growin such plants as you never really know what might turm up. For example, I received a D. stolonifera tuber from him and it turned out to be ssp. porrecta! I have about 10 plants of D. petiolaris "Kunnunurra" accelerating quickly to the 1 cm diameter mark. Had also germinated D. falconeri - according to Allen's suggested 32-35 C 2-3 week treatment of the sown seed (on peat)- but lost all seedlings presumably to damping off. Next attempt, I'll keep the falconeri pot drier. Allen has also germinated D. banksii, D. lanata and other petiolaris types using this method. Establishing mature plants through purchase from Allen has not been successful for me: plants invariably arrive in the mail either dead or so weakened that they never recuperate. I think seed's the way to go and the seedlings are growing very quickly. Regarding other seed from Allen, D. regia, D. ramentacea, D. glabripes, D. sp. "Floating", D. venusta, D. admirabilis, D. spathulata forms have germinated but nothing as yet from D. acaulis, D. arturi types, D. stenopetala, D. gigantea, D. bulbosa "Eastern Wheatbelt", P. sharpii, P. vallisneriifolia, P. bohemica, D. pauciflora and a few others. Although I get a good germination rate for D. regia, most of the seedlings just die after attaining 4 or 5 leaves and before the first true root is formed. And my growing conditions are fairly cool (ca. 15-25 C) with well- drained peat/sand. Well, one of the muses' is tapping me on the shoulder and pointing one of his fingers over at the lab door. I think that I'll reluctantly call it quits for now. Although I would not be able to contribute as often as I like, I would still like to hear the latest on the email waves, so keep them coming! If something new and interesting surfaces though, I'll be sure to network it. Good growing......

Not apical meristem, but intercalary meristem. I too have heard that water-absorbant jells may promote fungus growth. I have not heard about toxic effects, but the chemical that they are made of is similar to a chemical which is toxic to humans (and much used for electro- phoretic jell-rigs). Somehow the name of the stuff escapes me. I knew a guy in Connecticut who grew Nepenthes under metal halide, or a similar light source. The thing was big, hot, heavy, and undoubtely expensive to buy and run. i did not like the looks of the yellowish light, and neither did his nepenthes. Nevertheless, the plants grew, and the heat was a benifit in a cold Connecticut basement. It threw a lot of light, but the largbe circular area of irradiance was a lot harder to work with than a linear tube-lit area. I'd say forget halides and stick with flourescents.

I can't remember whether we treated it as a normal Utric. (i.e. standing in water year round) or let it dry out over summer... The plants in the wild near us are growing in a mud/sand soil along with D. pygmae, which turns rock hard in summer so the second method might be best. Speaking of seeds, the D. peltata seeds are currently in the collection phase - you don't get as many seeds per pod as a Sarracenia (approx. 250 seeds per pod for our S. purpurea ssp. venosa plants last year), but since there are around 6 pods per plant, there should be enough to go round. >It's funny---whenever you two talk about seasonal plants like >Sarracenia I always have to stop and add six months to the date to see >if it makes sense.

"Bush moss" is a general term I use for any moss which isn't sphagnum moss :-) I'm not sure what mosses you have growing in the U.S., but the types of mosses that cause problems are those that are found growing on rocks, trees, in lawns etc. Most have fine thread-like "leaves", forming dense mats that form a distinct layer on the soil surface (making it easy to remove). Apart from smothering the soil, the moss shrinks when dried out, leave a gap around the edge of the pot. This also occurs with peat, but peat will expand again when soaked in water - the moss doesn't. The shrinkage also causes the moss to lift away from the peat below, causing most small plants (e.g. pygmy Drosera) that survive being smothered by the moss to die from lack of moisture. Live sphagnum causes very few problems, but most of the sphagnum in the pots in the dormant/dead variety. Of the little that does grow, the tips tend to turn black as if burnt, although the pots containing only sphagnum moss (e.g. Cobra lilies) seems to grow without many problems. I'll see how the moss-free pots perform, and possibly replant fresh, live sphagnum if the results aren't up to scratch. ################### From: Robert.Allen@Eng.Sun.COM (Robert Allen) Date: Wed, 2 Oct 91 21:27:02 +1000 Subject: stuff The dreaded grey mold has struck my newly planted seeds. :-( :-(.

Since this is my first winter growing CP I am a little concerned with how to properly rest the plants. I had almost all of my plants outside for the spring and summer and they did very well. I plan on leaving some of the plants outside all winter such as S. Purpurea which grows in the wild nearbye. I don't have a greenhouse but just finished making a large light rack where I currently have my orchids. The rack is in my bedroom where the temperature will not get too low because I have to live there. I have 2 options. Leave the plants outside where night temp will sometimes fall below freezing, or inside where the temperature will not fall below 50 F. Naturally I don't want to kill any plants with the low outside temperatures but I am concerned that the indoor temperatures will not be low enough to start the plants hibernating. How low should the temp be to initiate hibernation? I water my CP by leaving them in trays of water which has worked well so far. I understand that during the rest period, watering should be reduced. Should I remove the plants from the water trays and occasionally water-from-the-top, or would it be OK to leave them in the trays with a lower water level? I know different plants will have different needs but I am just looking for some rule of thumb ideas. I have mostly Sarracenia, Drosera, and utricularia.

We keep our Sarras in tray during the growth season (spring-early autumn/fall) but then only water to keep them damp/moist during dormancy. Same for Droseras except we always water from the top (not enough trays!). Utrics can be kept in their trays all year. Ours are grown in a unheated glasshouse, but those in the bog garden survived OK even though they were rained on often (the water table is about 4"? from the surface of the bog or less). However, we didn't have any frost problems this year (greenhouse effect?), so maybe that helped. >>Perhaps you could pack the pots in compost, which if chosen >>carefully will generate some heat, and put moss over the tops? >>Keep the root system from freezing seems to be the mesg here. If freezing conditions are likely, you could try spraying mist all over the plants. The water freezes all over the plants and actually insulates them from sub-zero temperatures.

Purpurea >which grows in the wild nearbye. Important topic, hibernation, and one I don't think you should disregard. Even plants that don't form real hibernacula or phyllodia, but rather just slow down in growth, in my mind benefit from winter dormancy. I take a very dim view of people trying to grow various plants (i.e. tuberous Drosera) continuously. So, each year as winter approaches I inventory all my plants and give each an appropriate treatment. By far, most of the tropical Drosera and Utricularia in your collections do not need any winter dormancy. This includes D. capensis. The North American Drosera (excluding capillaris and brevifolia) can take light frosts in my experience. Obviously, plants local to N.Jersey etc can take colder temperatures during the winter---with an important difference. Plants in the wild have a couple of feet of snow and ice insulating them from the biting cold. Plants in an exposed pot do not. In Arizona, I let them get down to about freezing for a couple of weeks. They'll come out of dormancy when they want to. I keep a few plants in the fridge if they like a very long dormancy (some D. anglica from Rob M stay dormant 9 months out of the year for me!). I think what is important here is to not interfere with them when they are trying to go dormant---trying to prolong their growing time seems to exhaust them and then they can't form large enough winter buds when they finally do bed down. Same treatment with my Sarrs, except for northern or mountain plants like purpurea purpurea, oreophila, or rubra jonesii. These I let FREEZE SOLID for a couple of months. They LIKE it! What is more, scale and pests do not! Freezing them is something I was worried about, although grower Paul McMillan swears by it. This last winter I did it and they loved it. I'm not talking about putting them in the freezer of a refrigerator---that's probably too cold. Anyway, with these exceptions, most of your winter plants will do well just being kept chilly---you know, 40--50 F with occasional frosts I've got three different clones of intermedia from the USA, one supposedly `Giant.' But it isn't too impressive. I have recently gotten a clone that is actually larger, and produces big stemmy plants. It's also producing seed and I think I'll have enough to stuff the mattress AND feed the soviets. As for my Cuba and also my `tropical' and `Mt. Roraima' forms, these are all plants from seeds (I think) that Rob M. sent me some time ago. Not anything remarkably different in any way, at least not yet. I'll be interested to see if they form hibernacula this winter. >Anyway, I seem to remember reading somewhere (Slack, maybe?) that this >species' seeds usually germinate quickly and easily. So I wonder if maybe >the seeds I got are either old or duds. Has anyone else got these seed >bank seeds to sprout?? I've had a couple seedbank Nepenthes sprout but that was a batch from long ago. None of this new stuff came up. I didn't do anything fancy. Just put them on the soil surface and waited. I thought I remember reading (Slack, maybe?) that Nepenthes seed were fast to germinate, but that doesn't seem to be the concensus of the people I know. Well some news from the (radiatively chilled) greenhouse. My U. calycifida from Christoph Belanger flowered and, much to my boredom, turned out to be a clone of my `spotted flower' form. Snore. BUT, some good news from the Byblis front. I attacked many individuals with my tuning fork and found the following: 1)B. gigantea seems to have some swelling ovaries. Seems some pollination efforts may have worked. 2)My B. liniflora `Kununurra,' which Allen thinks is a new species, has finally succumbed! Up til now I have been entirely unsuccessful in getting pollen. The tuning fork did the trick. 3)B. liniflora `Darwin'---tuning fork also works, but may not be necessary. This plant is really civilized---you touch the anthers with the fork, and the pollen is released and falls directly onto the (female) stigma. Quite cooperative, and this was appreciated by me. Also I am thrilled to note my specimen of Genlisea (hispidula?) from Christoph is getting quite large and my leaf cutting from it struck! I immediately took three more cuttings. If I build up a base of plants I'll be able to start distributing them, as long as I don't do anything stupid. Lastly, something VERY STRANGE has come up in my D. banksii seed pot. I have never seen this plant, nor do I know anything about it. Well, Something is in my pot which looks like a cross between a tuberous and a pygmy Drosera. It looks most like D. pygmaea, but instead of forming a snug ground hugging rosette it is erect, holding its leaves like a tiny D. capensis. What is more, the elliptical leaves (1 mm across) are bright red (lamina, the petioles are green), and peltate. I've never seen anything quite like this plant. It is surely very similar to a pygmy of some sort, but I have about 35 spp of those and this is different. Anybody ever grown D. banksii? Does this sound like it? Well, gotta go.

I know that many of the "rainbow" sundews (peltata etc.) produce a rosette of leaves before sending up the main stem, but never that small. I'll have a look at our books, but something that springs immediately to mind is that for some reason, Erickson placed banksii at the end of the drosera section of her book ("Plants of Prey"). This always puzzled me, since it should have been with the other rainbows. Maybe it is a weird plant! The other possibility is that it really is a pygmy "weed" - not all of them are ground huggers (I think). ****** According to Rica Erickson's book, it sounds like you've got a D. banksii seedling! "Lower leaves minute and withered, increasing in size to about 1mm across (huge!) on very slender leaf stalks up to 5mm long..." Suprisingly, it seems that this plant is not tuberous "..no bulb." and may be an annual (not stated, but possible - keep your seeds if you get any, just in case). Now I know why it was stuck at the end of the Drosera section... Some of our newer Utrics are flowering this year (yey!). U. capensis has a nice but small flower which is pale purple on the corolla with two dark spots on the lower lip, just below the "large" (comparitively) palate. The upper lip of the corolla it quite pointed and notched/divided. Looks very nice. The U. peltata and U. praelonga (bought as a U. tricolor :-( ) have several flower stalks, as does the U. pentdactyla and (of course) U. sandersonii, livida and subulata (which is growing in most pots in the greenhouse - @#$#%^#$ weed!).

Others spend a fair amount of time as a rosette before producing a rather short "climbing" stem. 0-2 months in the rosette phase would be about right. The rosette may be for the plant to gain some energy before producing the "climbing" stem - remember that it has been feeding off its tuber while struggling to the surface. The rosette may also act as a brace for the stem to protect it against strong winds ... any budding engineers out there want to test this?

D. falconeri has a rosette of Dionaea (VFT) like leaves, which have the same broad leaf stalk but instead of the "bear-trap" it has an almost perfectly round leaf. The new leaves point upwards and when they open, they gradually move down to ground level (judging by the young leaves on my plant). Most of the plants on sale had somewhat red-tinted leaves, but mine is rather green (should change with sunlight). I've no idea what the flowers will be like, but the usual, dull white flowers are more than likely. Also in the pot (and one or two of the others) is a small amount of Utric. I'm hoping it's something different from what we've already got, but I've a nasty feeling it's U. sublata :-( (at least it came for nothing) Does anyone know where this species originates from? ################### From: s883351@minyos.xx.rmit.OZ.AU (John Taylor [The Banshee]) Date: Sat, 9 Nov 91 15:45:56 +1100 XSubject: Re: D. falconeri >He doesn't get concerned with liverworts.

It grows around the Finniss River in the Northern Territories (wherever that is). The Sept./Dec. CPN has a nice picture of D. falconeri on the cover, along with an article on the D. petiolaris "complex". An old article in CPN says the plant is found in soils with an alkaline pH of 8. This species may go dormant in the dry season. Pyrethrum: I have a catalog from a place that sells Pyrethrum insecticide. They also have a gizmo, price of $43, that automatically dispenses the spray every 15 minutes. A month supply of Pyrethrum goes for $10. Look locally first from greenhouse suppliers or from places that sell organic gardening supplies. Also, check the labels, "Red Arrow" is the brand name of one insecticide that contains pyrethrum. I've been just using Safer Insecticide Soap myself although it doesn't seem to kill scale. Also from the catalog, you can get "beneficial insects". They list such things as "scale predators", lady bugs, mantis egg cases, "mealybug predators", "beneficial nematodes", green lacewings etc. A recent rec.gardens messages stated that a spray containing Ivory soap + water was just as effective as the Safer insecticide. The phone #'s for getting free catalogs are 274-9676 and 331-3994 (both 1-800). D. collinsiae: My plant is in flower. Nice lavender flowers.

(I add that mine, which get the deluxe northern Arizona catered hibernation service, attended to by the lovely and talented Bridgett Meyers-Rice, do well). He also thinks hibernation is not induced so much by temperature drops as decrease in light exposure. He said, for example, he's induced hibernation in D. rotundifolia by putting them in the shade, same ambient temperature. He doesn't get concerned with liverworts. He sort of likes them. Don, he says he's ``not 100% sure in regards to the P. kondoi either. My large plant at this point appears almost identical to a neighboring P. esseriana.''

He has some remarkable sized P. zecheri plants exceeding 7 inches (18 cm) in diameter. Very beautiful lance-shaped leaves that color up with a light tinge of red in good light. One P. colimensis plant in winter dormancy had over 12 divisions and flowering profusely. This plant looks very similar to P. caudata except for slightly shorter leaves and flower characteristics (fatter spur). He claims that certain Mexican Pings require a basic mix for better than mediocre growth, examples being P. gypsicola, P. zecheri, P. X "George Sargent", P. moranensis rosei, and P. X "mola". One favoring an acidic mix is P. colimensis. His mixes are 1:1 peat/vermiculite with 1 tablespoon of limestone (CaCO3) per 700 mL of mix and pure milled Sphagnum. I noted that the substrates for his Pings. are just barely moist. I think that the most important variable in his growing success is the cool temperatures afforded by his basement (ca. 55-75 F).

Rob, this is good data (the laser printer is churning out a hard copy). So he uses pure milled Sphagnum for the ones that like acidic, and the peat/vermiculite with a smudgmo of CaCO3 for the others.

Astro lesson 1: Take your latitude (I haven't the slightest idea of where Palo Alto Cal is, so I'll guess 35 degrees N), and subtract it from 90. That's the angular distance of the sun from the horizon at noon on the Equinoxes (around Sept 22, March 22). At that time the sun rises due east, sets due west. On the longest day of summer, the sun reaches an elevation 23.5 degrees higher than this. It rises NE, sets NW. The shortest day of winter, subtract 23.5 degrees, sun rises SE, sets SW. The long/shortest days are on about June 22, Dec 22., not necessarily in this order. So anyway, the sun changes in max elevation by 47 degrees---that means a big change in light and heating.

Whatever the price, there will be a fixed number of buyers. Mostly research and locations of higher learning. There's no cultural info. My advice is to check it out from the library, and photocopy the first couple of chapters since they contain some useful information on habitats. There are a couple of other interesting sections, so hit those with the copier.

The mix our plants came in definitely contains perlite, so it is quite likely to be a 50/50 peat/perlite mix - they may actually originate from Alan Lowrie but I can't be sure of Gardenworld's sources.

Well, until I hear that it has been officially renamed as a subspecies of peltata, I'm going to continue calling it D. auriculata. (and even then I may not change the name - there are several differences between them that should warrant it being a separate species, at least in my book). ################### From: MAHARAJ@MCMASTER.BITNET Date: Tue, 12 Nov 91 11:11:34 +1100 Subject: Mexican Pings >Rob, this is good data (the laser printer is churning out a hard copy). >So he uses pure milled Sphagnum for the ones that like acidic, and the >peat/vermiculite with a smudgmo of CaCO3 for the others.

No CaCO3 added to water, though Joe Mazrimas swears by this method (CPN, ca. 1978) but uses agricultural lime (Ca(OH)2). I remember reading in CPN that vermiculite is a special soil aeration medium in which the CaCO3 or Ca(OH)2 can embed or 'hide-out' in its clefts or pores. Subsequent waterings can leach out the calcium salts into the growing medium, thereby maintaining a slightly alkaline pH which most Mexican Pings. seem to appreciate or even need. Thus a combination of alkaline watering and growing medium MAY be too much for these calciphiles and I would stick to one technique and not both. He does not place his pots in trays, as most Mexican Pings need good drainage. Grant waters from above -very mildly- when necessary, which is about once a week or so in his naturally humid and cool basement. I should correct my- self from yesterday's message: P. colimensis will happily grow in BOTH milled Sphagnum and the peat/vermiculite/CaCO3 mix and not just the former one. There appears to be certain species - P. colimensis, P. caudata, P. agnata, P. pachuca and P. ehlersae - which do not favor a certain mix, but time and further experimentation will tell.

It seems to me that peat is pretty darned acidic, and by adding a little bit of CaCO3, which is pretty insoluble to boot, you wouldn't do much to change the soil acidity. So, I contemplate several options... 1)In spite of my intuition, the soil does become alkaline. 2)Instead of needing alkaline, the Pings benefit from the Ca++ ions. 3)This is something ineffectual the CPer does to please him/her self. 4)Something else is going on (aka the cover your a** possibility) Comments on acid/base reactions, Rob M? On the usefulness of Ca++ to plants, Mike? >On a similar subject, do crosses with bicalcarata inherit the fangs? Yep! Now what you need to do is cross bicalc with a Nepenthes with a broad, shiney red lip at the entrance. (I think it's called the peristome). That would be pretty obviously carnivorous! >Thanks John.
