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 seeds of the cacao tree (Theobroma cacao), the best known species of the genus, are used for making chocolate. Cupuaçu (Theobroma grandiflorum), mocambo (Theobroma bicolor) and capacui (Theobroma speciosum) are also of economic importance.

Taxonomy
The generic name is derived from the Greek words θεός theos meaning "god" and βρῶμα broma meaning "food" translating to "food of the gods".

Uses
Several species of Theobroma produce edible seeds, notably cacao, cupuaçu, and mocambo. Cacao is commercially valued as the source of cocoa and chocolate.

Theobroma species are used as food plants by the larvae of some moths of the genus Endoclita, including E. chalybeatus, E. damor, E. hosei and E. sericeus. The larvae of another moth, Hypercompe muzina, feed exclusively on Theobroma cacao.

An active ingredient of cacao, theobromine, is named for the genus.
