herbaceous plants in the family
Gesneriaceae
Gesneriaceae, the gesneriad family, is a family of flowering plants consisting of about 152 genera and ca. 3,540 species in the tropics and subtropics of the Old World (almost all Didymocarpoideae) and the New World (most Gesnerioideae), with ...
native to western South America. It is classified in tribe Gloxinieae and is closely related to the genus ''
Kohleria'', in which some of its species were previously included. The genus ''Parakohleria'' has recently been synonymized under ''Pearcea'', a conclusion later supported by molecular analyses that showed that ''Pearcea hypocyrtiflora'' was nested within the former Parakohlerias.
The best-known and most widely cultivated species is ''Pearcea hypocyrtiflora'', a low-growing herb with attractively marked leaves and unusual bubble-like red or orange flowers.
