>you argue against the patchy environment hypothesis for the evolution of
sex change in Arisaema (which suits me fine -- I have no stake
in it).  What about the size advantage hypothesis?  That find favor with =you
or any other AEG member?

It sounds logical. I don't know if the plant itself has to be bigger but =I
guess the tuber/rhizome has to store more reserves to produce seeds so th=at
one definitely has to be bigger. However, I measure and weigh most of my
Arisaema each year and I have found that some fruiting specimen reverted
back to the male state the year after, WITHOUT a significant decrease in
size or weight of the tuber. And besides, why flower at all with just mal=e
flowers? Why not wait before the plant is big enough to produce both type=s
of flowers? If you gonna do it, do it good.....

We should close this (and continue one-on-one) because other AEG members
may dislike having their email cluttered up.

I'm sure other AEG-members have their own thoughts on this and can let yo=u
know through the mailing list. In the end, your research will be of
importance to them too.
