CASSAVI, n. A plant, of the genus Jatropha, of different species. The roots of the manihot or bitter cassada, and of the janipha, are made into a kind of bread which serves for food to the natives of Africa and the West Indies, and they are also roasted and eaten like potatoes. They yield also a great quantity of starch, which the Brasilians export in small lumps under the name of tapioca.
