I share Jim's interest in the "obscure Pinellia species."  Besides the =
four common ones Jim mentions, TROPICOS lists four other  species as =
apparently valid (P. cochinchinensis, fornicata, integrifolia and =
peltata), however, the citation for P. cochinchinensis Wright is merely =
to a list of seeds received from "Siagon, Cochin, China."  It gives as a ==
synonym for this species Arisaema cochinchinensis Blume, changes the =
genus to Pinellia, credits W.F.Wright, but gives no citation.  Is this a ==
valid citation?

Does anyone know of sources for these other species?

I guess my question basically boils down to "How do you tell a Pinellia =

an Arisaema?"

Botanists?
