Deppea is a genus of flowering plants in the family Rubiaceae, placed in the order Gentianales and, within the subfamily Dialypetalanthoideae, the tribe Hamelieae. It comprises around a dozen accepted species of slender shrubs and small trees with oppositely arranged (occasionally whorled) leaves. The genus ranges natively from Mexico through Central America, with a disjunct presence from Brazil to Argentina; its centre of diversity lies in the mountain forests of Mexico and Guatemala.
The genus was described in 1830 by Diederich Franz Leonhard von Schlechtendal and Adelbert von Chamisso, with Deppea erythrorhiza designated as the type species. It commemorates the German naturalist Ferdinand Deppe (1794-1861), who collected the type material during a botanical expedition to Veracruz, Mexico, with C.J.W. Schiede in 1828-1829.
The genus's best-known member is Deppea splendens, the "golden fuchsia," a cloud-forest shrub or small tree bearing showy, pendulous, tubular red-and-yellow-orange flowers pollinated by hummingbirds. Discovered in Chiapas in 1972, it was described only in 1987, by which time its sole known wild population had already been cleared for farmland; it survives today solely through cultivation from seed collected before its extinction in the wild, grown in botanic gardens such as the Huntington and San Francisco Botanical Garden. Its dramatic rescue-from-extinction history has made it the genus's most horticulturally and conservation-notable species, though most other Deppea species remain little-studied shrubs of Mesoamerican and South American forests.
Etymology
Named in honor of the German naturalist Ferdinand Deppe (1794-1861), who collected the type species during a botanical expedition to Veracruz, Mexico, with C.J.W. Schiede in 1828-1829.
Distribution
Deppea occurs from Mexico through Central America (Costa Rica, El Salvador, Guatemala, Honduras, Panama), with a separate presence from Brazil to Argentina. Its centre of diversity is in the mountains of Mexico and Guatemala.
Taxonomy Notes
Described in 1830 by Schlechtendal & Chamisso, with Deppea erythrorhiza as the type species. Placed in tribe Hamelieae within subfamily Dialypetalanthoideae of family Rubiaceae (order Gentianales, per GBIF). GBIF's checklist lists 13 accepted species.
Conservation
The genus's best-known species, Deppea splendens (the golden fuchsia), is extinct in the wild: its only known population in Chiapas, Mexico, was destroyed for farmland, and it now persists only in ex-situ botanic-garden and private collections grown from seed collected before its wild extinction. No genus-wide conservation assessment was found; this status applies specifically to D. splendens among Deppea's species.
