Afzelia
Afzelia is a genus of plants in family Fabaceae. The thirteen species all are trees, native to tropical Africa or Asia.
The genus name of Afzelia is in honour of Adam Afzelius, a Swedish botanist and an apostle of Carl Linnaeus.
Evolutionary history
Afzelia is closely related to, and the sister taxon of Intsia. Both Afzelia and Intsia, along with Brodriguesia form the clade Afzelieae within the legume subfamily Detarioideae.The earliest definitive record of Afzelia in the fossil record is a well-preserved, compression fossil of a leaflet from the late Oligocene Guang River flora of northwestern Ethiopia, named Afzelia afro-arabica. Numerous other records, some which may represent Afzelia, are known fossil wood occurrences from the Paleogene and Neogene of Africa and Asia and are included in the form genus, Pahudioxylon.

Uses
The seeds are red and black and are used as beads.
The wood is often used as the surface material for outdoor velodromes.
The highly figured wood of the Asian species, Afzelia xylocarpa, is sold as Afzelia xylay. The seeds and bark of this species are used as medicine.
The dense and wavy wood of an Afzelia africana is used in ship-building.
