<< Which species of colocasia and xanthosoma grow in Mexico? And how can I
make the difference? >>
Colocasia esculenta might be grown as a vegetable, or be present as a garden
escape; it is not native to mexico. Colocasia has heart-shaped leaves,
generally smooth. Xanthosoma, of which there are probably a number of spp.
in Mexico, has saggitate leaves with thick ribs, and often quilted at the
veins. It has a collecting vein running all the way around the leaf, just
inside the margin.
