Begonia hirtella
Scientific classification
Kingdom: Plantae
(unranked): Angiosperms
(unranked): Eudicots
(unranked): Rosids
Order: Cucurbitales
Family: Begoniaceae

Begoniaceae is a family of flowering plants with over 2000 species occurring in the subtropics and tropics of both the New World and Old World.[2] 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.[3] Phylogenetic work supports Hillebrandia as the sister taxon to the rest of the family.[3] 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.[4] Members of the genus Begonia are well-known and popular houseplants.
