<< I would be interested in having opinion on a couple of questions which
arose when I showed five Arisaema species at the Scottish Rock Garden
Club show in Aberdeen, Scotland on Saturday.

Because I was anxious that the pot of A. flavum did not 'go over' before
the show, I kept it outside uncovered and it was subject to several
heavy rain showers the previous day. At the show I noticed that all the
tips of the leaves had drips of water hanging from them and there
appeared to be active secretion of water taking place. A. flavum is a
species from dry habitats and mine came from a very arid site in Tibet.
Could this be a plant mechanism to get rid of excess water? - has anyone
else observed this with flavum, or with other species?

2nd question - A. consanguineum ssp. biradiatifoliatum was much admired
and I was asked about the name biradiatifoliatum. Anyone know to what it
refers? I notice that while the leaflets are like the spokes of a wheel,
in each of the 4 seedlings, one leaflet is not in the same flat plane as
the rest but is carried at a slight upwards angle - is this relevant?

Thanks

I haven't noticed anyone answering you, at least on the list, and I can't
answer the first question, about A. flavum.

Re the "odd" leaflet on the other, it appears to be the standard appearance
for arisaemas of section Sinarisaema. If you've noticed how they emerge from
the stalk, one leaflet leads the rest, and this is the one that stays "out of
step". I just had A.c. biradiatifolium flower from seed for the first time
and agree that it is especially attractive.
