Anyway, on Arisaema chromosome numbers:  My lab is trying to understand
chromosome number evolution in Arisaema by comparing the numbers in close=ly
related and distantly related species.  As several contributors to this
thread have explained, chromosome numbers and hybridization go together.
>From the great diversity of chromosome numbers in Arisamea (and the very
high numbers, such as n = c.140), it seems that hybridization has playe=d a
great role in the past evolution of Arisaema diversity.
