Abstract

Manihot is a New World genus with a 100 species. Two species have been introduced in Southeast Asia. M. glaziovii (distinctly peltate leaves, no ridges on the ovary and fruit), a small tree, was cultivated for its latex, but Hevea brasiliensis outcompeted this species. M. esculenta (leaves not or hard1y peltate, ridges along ovary and fruit), usually a shrub, is a major root crop for humans as well as for animals, it is known worldwide as cassava, manioc, or tapioca.
