Dear Christophe,

There will be few Colocasias and several Xanthosomas in Mexico! Colocasia
is an Asian genus introduced to the Americas, while Xanthosoma is a native
American genus. As a rule of thumb, Colocasia will have a peltate leaf
blade while Xanthosomas will have a sagittate leaf blade (there are a few
rare exceptions to this 'standard' rule, but not worth discussing here).
The problem will come when/if you encounter Caladium, which like Colocasia
has a petlate leaf blade, and occurs commonly with all-green leaves! But
Caladium will generally be smaller than any Colocasia you may encounter in

Hope this helps. Write to the list again if you have any further
questions, and I will try to give more details.

Good luck in collecting!
