" There are two species, bitter and sweet, from which the cassava of commerce is prepared in the West Indies, tropical America, and Africa. The bitter (Manihot utilissima) is the more important; this has a poisonous sap, but by grating, pressing, and baking the root the poisonous qualities are removed. The sweet (Manihot Aipi) is used as a table vegetable."
