− | '''Gesneriaceae''' is a [[family (biology)|family]] of [[flowering plant]]s consisting of ca. 150 genera and ca. 3200 species in the [[Old World]] and [[New World]] tropics and subtropics, with a very small number extending to temperate areas. Most species are perennial [[herb]]s or [[subshrub]]s but a few are woody shrubs or small [[tree]]s. On the basis of both morphological and biogeographical differences the family is divided into two major subfamilies: subfamily Cyrtandroideae in the [[Old World]] and subfamily Gesnerioideae in the [[New World]]. The biggest and most widespread genus is ''[[Cyrtandra]]'', with about 600 species widely distributed in [[Southeast Asia]], [[Malaysia]], [[Indonesia]], the [[Philippines]], and the islands of the [[Pacific]] as far away as the [[Hawaiian Islands]].

− | Several genera in the family have become popular as houseplants. The most familiar members of the family to gardeners are the [[African Violet]]s in the genus ''[[Saintpaulia]]''. Gesneriads are divided culturally into three groups on the basis of whether, and how, their stems are modified into storage organs: [[Rhizome|rhizomatous]], [[tuber]]ous, and "fibrous-rooted", meaning those that lack such storage structures (although all gesneriads have fibrous roots).

− | The genus ''[[Rehmannia]]'' has sometimes been included in Gesneriaceae but is now referred to the family [[Scrophulariaceae]].
| |
− | | |
− | Botanists who have made significant contributions to the systematics of the family are [[George Bentham]], [[Robert Brown]], [[B.L. Burtt]], [[C.B. Clarke]], [[Olive M. Hilliard]], [[Joseph Dalton Hooker]], [[William Jackson Hooker]], [[Elmer Drew Merrill]], [[Harold E. Moore, Jr.]], [[Conrad Vernon Morton]], [[Henry Nicholas Ridley]], [[Laurence Skog]], [[W.T. Wang]], [[Anton Weber]], and [[Hans Wiehler]]. Several researchers are currently working on this group and the generic classification has been changing rapidly.

− | The family name is based on the genus ''Gesneria'', which honors [[Switzerland|Swiss]] [[humanism|humanist]] [[Conrad Gessner]].
