The subfamily Colocasioideae of the Araceae is a group of 15 genera and about 200 species, the majority ofwhich are terrestrial herbs with thick or tuberous stems. Geographically, the genera and species are about equally divided between tropical Asia and the neotropics. The subfamily is defined by a suite of floral features, by the presence of anastomosing laticiferous elements in the vegetative parts of the plant, and by the very distinctive colocasioid venation of the leaves which permits ready recognition of the subfamily even in plants lacking flowers.
