What is "begoniaceae"

Begoniaceae \Begoniaceae\ n. a natural family of monoecious succulent herbs or shrubs of tropical and warm regions especially America.

Syn: family Begoniaceae, begonia family.

Begoniaceae is a family of flowering plants with two genera and about 1825 species occurring in the subtropics and tropics of both the New World and Old World. All but one of the species are in the genus Begonia. The only other genus in the family, Hillebrandia, is endemic to the Hawaiian Islands and has a single species. Phylogenetic work supports Hillebrandia as the sister taxon to the rest of the family. The genus Symbegonia was reduced to a section of Begonia in 2003, as molecular phylogenies had shown it to be derived from within that genus. Members of the genus Begonia are well-known and popular houseplants.
