A. flavum & A. consang. ssp. biradiatifoliatum

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?
