The Sterculiaceae is also known as the cacao family. It is a mostly tropical and subtropical family with 65 genera and 1000 species and takes its name from the genus Sterculia, which is named in turn from the Latin stercus, "dung or manure," from the unpleasant smell of the flowers and leaves of some species. The family is composed mainly of shrubs and trees with simple, alternate leaves and flowers with five connate sepals and five or zero petals. As is the case with other families, a revision is likely in the works for Sterculiaceae and its close relatives Tiliaceae and Bombacaceae. Some systemists place the Sterculiaceae into the larger family Malvaceae. Many of the species in this family yield valuable lumber, and its best known products are chocolate and cocoa from Theobroma cacao and kola nuts from the genus Cola. Several other familiar genera are Brachychiton and Fremontodendron.
