Theobroma Theobroma Theobroma is a genus of flowering plants in the mallow family, Malvaceae, that is sometimes classified as a member of Sterculiaceae. It contains roughly 20 species of small understory trees native to the tropical forests of Central and South America. The generic name is derived from the Greek words θεός ("theos"), meaning "god," and βρῶμα ("broma"), meaning "food". It translates to "food of the gods." "Theobroma cacao", the best known species of the genus, is used for making chocolate. Several species of "Theobroma" produce edible seeds, notably cacao, cupuaçu, and mocambo. Cacao is commercially valued as the source of
Tree and frost, and the seed germinates in the spring. Pine cones may similarly be hoarded by red squirrels, and grizzly bears may help to disperse the seed by raiding squirrel caches. The single extant species of Ginkgophyta ("Ginkgo biloba") has fleshy seeds produced at the ends of short branches on female trees, and "Gnetum", a tropical and subtropical group of gymnosperms produce seeds at the tip of a shoot axis. The earliest trees were tree ferns, horsetails and lycophytes, which grew in forests in the Carboniferous period. The first tree may have been "Wattieza", fossils of which have been found
