zuzu said: I never even would have identified the flower form as an umbel.
I'm still having trouble seeing it
and not just umbels. I'm finding several/many of the flower forms are difficult to differentiate. As to Underground Structures, fahgedaboudit! I've read there was an aroid expert who spoke of Xanthosoma US as "chubas" because there was relatively universal agreement to disagree on Corm vs. Tuber.
Thanks for the update Dave.
