Tuberous edible perennial plant (Manihot esculenta) of the spurge family, from the New World tropics.It is cultivated for its tuberous roots, from which cassava flour, breads, tapioca, a laundry starch, and an alcoholic beverage are derived. It has conspicuous, almost palmate (fan-shaped) leaves and fleshy roots. Different varieties range from low herbs through many-branched shrubs to slender, unbranched trees adapted to diverse habitats.* * *
▪ plantalso called Manioc, Mandioc, or Yuca(Manihot esculenta), tuberous edible plant of the spurge family (Euphorbiaceae) from the American tropics. It is cultivated throughout the tropical world for its tuberous roots, from which cassava flour, breads, tapioca, a laundry starch, and even an alcoholic beverage are derived. Cassava probably was first cultivated by the Maya in Yucatán.A cyanide-producing sugar derivative occurs in varying amounts in most varieties. Primitive peoples developed a complex refining system to remove the poison by grating, pressing, and heating the tubers. The poison (hydrocyanic acid) has been used for darts and arrows.An extremely variable species, cassava probably is a hybrid. It is a perennial with conspicuous, almost palmate (fan-shaped) leaves resembling those of the castor bean but more deeply parted into five to nine lobes. The fleshy roots are reminiscent of dahlia tubers. Different varieties range from low herbs through many-branched, 1-metre- (3-foot-) tall shrubs to slender, unbranched 5-m trees. Some are adapted to dry areas of alkaline soil and others to acid mudbanks along rivers.All the approximately 160 species of the genus Manihot are sun-loving natives of tropical America. Ceará rubber is produced from M. glaziovii, from northeastern Brazil. Food items such as the gelatinous fufu of West Africa and the bami mush of Jamaica come from cassava. Additional cassava products include an alcoholic beverage made by Indians in South America, the powdery casabe cakes of Yucatán, and tapioca, the only cassava product on northern markets.* * *
