Dactyladenia is a genus of flowering plants in the family Chrysobalanaceae, within the order Malpighiales. It comprises roughly 31 to 32 recognized species — Wikipedia cites "about 31," while the GBIF Backbone Taxonomy lists 32 accepted descendant species, a minor variance rather than a real disagreement between sources. The genus was formally described by the Austro-Hungarian botanist Friedrich Welwitsch in 1859, in his work Apontamentos Fito-geograficos sobre a Flora da Provincia de Angola na Africa Equinocial (GBIF records the original place of publication as "Welw., Apont. 572").
Species of Dactyladenia are native to western and central Africa, ranging from Liberia in the west to Angola in the south. GBIF's distribution data, sourced from the World Checklist of Vascular Plants, lists the genus across a broad swath of the Guineo-Congolian region: Angola, Benin, Burkina Faso, Cabinda, Cameroon, the Central African Republic, Congo, the Democratic Republic of the Congo, Equatorial Guinea, Gabon, Ghana, Guinea, the Gulf of Guinea Islands, Ivory Coast, Liberia, Mali, Nigeria, Sierra Leone, and Togo.
As members of Chrysobalanaceae — a family of trees and shrubs sometimes known for the cocoa-plum and related fruits — Dactyladenia species share the family's generally woody habit. A herbarium type specimen of Dactyladenia cinerea, digitized by the Naturalis Biodiversity Center, documents the genus's characteristic leaf and branch morphology. Detailed genus-wide information on growth habit, ecology, cultivation, traditional uses, and conservation status was not found in the sources consulted for this profile.
