Hello CPers,
its been a long time since I contributed to the discussions
- been far too busy with ice cream! There are a couple of
recent items I can contribute to:
Paul,
regarding P.heterophylla:
>Has anyone flowered the species Pinguicula heterophylla or
>seen it in flower?
Yes Stan Lampard has.
>The most commonly available plants have long narrow sinuous
>leaves that do not produce plantlets at their ends. The
>rarer type has identical leaves but they do produce
>plantlets on the leaf ends. There is also a type
>circulating with an attached Source Location name but it's
>not clear if this is the same as either of the two types
>described above or if it is different
Snip
>Any report on P. heterophylla from specified locations
>would be most welcome (for example, who was it that
>imported such a plant - WITH a named source location - into
>cultivation?).
'Common and rare' are relative terms and this may depend
where geographically you are. One plant which was circulated
quite widely a year or two ago originated from Conception
papalo. Stan grew a vast army of these from seed which may
now be the most widely grown form in the UK and possibly
else where. This form does *not* produce plantlets on the
leaf tips, so is probably the first form you mention. I
cannot remember if Stan collected the seed him self whilst
in Mexico or whether they came from Alfred Lau or Hans Luhrs
- I am sure Stan will remember the origin. By comparison the
plantlet forming 'Alfredae' plant (named I assume after
Alfred Lau) has been in cultivation for several years - the
plantlets being an excellent method of bulking the plant up.
I assume that the lack of understanding on Ping cultivation
has prevented the plant from being more widely cultivated.

>literature.
As well as being a genius on the cultivation of Mexican
Pings, Stans drawing skills as far as the flowers are
concerned is unequalled. I am sure he has drawings of the
Conception flower which if my memory serves me is white as
opposed to the violet flower of the 'Alfredae' plant. It
would be well worth a trip up to Birmingham to see Stan and
his drawings - if you timed things just right you may even
be able to see the flower your self!
Regarding the Drosera petiolaris complex:
Hello Frank and Tom,
my plants are under similar conditions to Toms, in an
aquarium at approx. 30deg C, with 12hr photoperiod. Tom got
me onto these things last year when he sent me some
D.petiolaris 'erect' seed which grew like cress and are now
nice sized plants - thank you very much Tom! Since then I
have obtained seed of most of the complex from Allen Lowrie,
the majority of which has germinated under the conditions in
the aquarium. Some of these are now reasonably sized plants,
so seed is probably a good option to establish these in your
collection. According to Lowrie temps above 25deg C are
necessary for germination.
As I have only been growing these plants for several months
I cannot comment on the long term success of growing these
plants. I had thought them to be difficult to grow as
friends of mine have imported plants in the past which have
usually perished in a couple of months. I am not sure as to
the reason for this, incorrect cultivation conditions or
whether the plants are totally confused when they get to the
northern hemisphere. Is there anyone out there who has had
long term success raising these things from seed?
Regards
Loyd
