Coca

 

(Erythroxylon coca), a shrub of the tropical family Erythroxylaceae, measuring 1–3 m high (sometimes 5 m). The leaves are broadly elliptical or obovate. The flowers, which are in the axils, are small, yellowish white, and five-petaled. The elongated red fruits are drupes. The coca bush almost never grows wild. It is cultivated in the tropics of South America and Asia. Coca leaves contain cocaine (up to 1.3 percent) and other alkaloids. One bush yields up to 5 kg of dry leaves per year. The leaves are harvested three to five times per season.
