Dear Bob,
The commoner blackish Aroids generally seen for sale are mostly Colocasia
sp. To tell them apart at a glance from the available Xanthosoma species,
look at the area where the two upper lobes of the leaf come together on
their way down to the petiole (stem). In Colocasias they will join before
they touch the petiole (peltate leaf blade), while in Xanthosomas they end
at the main ribs BEFORE these ribs continue down to the top of the petiole
(sagittate leaf blade). Hope this helps.
