The cassava or manioc (Manihot esculenta) is a woody Shrub of the Euphorbiaceae (spurge family) that is extensively cultivated as an annual crop in tropical and subtropical regions for its edible starchy tuberous root, a major source of carbohydrate. Cassava is called mandioca, aipim, or macaxeira in Portuguese, mandio in Guaraní, yuca in Spanish, mogho in Gujarati, balinghoy in Tagalog, and maniok in Danish.
