Here I am, trying another key, and having some problems. The chart that
Guy developed is elegant. The third characteristic, whether the central
leaflet turns up or down as it unfolds, has me puzzled, though. I was
looking at young leaves of A. taiwanense. I can't see a central leaflet,
as they all seem equal, round in a circle. As they emerge, mine all point
down, rather like the spokes of a folded umbrella. The leaflets are all
folded lengthwise, and as they open, the inner surface becomes the upper
surface. Is this what he means?
I have found a diagram of Arisaema parts in Pradhan's book, Himalayan
Cobra Lilies. This is very helpful for the terminology. I will sketch
that page before I return the book to the library.
