Baphia is a small genus of legumes that bear simple leaves.[3]Baphia is from the Greek word βάπτω (báptō-, "to dip" or "to dye"), referring to a red dye that is extracted from the heartwood of tropical species.[3][4] The genus is restricted to the African tropics. Baphia was traditionally assigned to the tribe Sophoreae;[5] however, recent molecular phylogenetic analyses reassignedBaphia to the tribe Baphieae.[6][7][8][9]
The status of the following species is unresolved:[12]
Baphia glauca A. Chev.
Baphia longepetiolata Taub.
Baphia madagascariensis C.H. Stirt. & Du Puy
Baphia megaphylla Breteler
Baphia radcliffei Baker f.
In 2023, a new species, Baphia arenicola was discovered growing in the deep sandy highland region of central Angola, part of the Kalahari sands, and was formally described to science. The floral characters most morphologically similar to Baphia massaiensis but with certain characters also comparable to Baphia bequaertii, with all three species found growing in the same region. Preliminary molecular analysis places the new taxon close to Baphia bequaertii. Whilst most Baphia form above ground shrubs and trees, Baphia arenicola grows as a geoxylicsuffrutex (often described as "underground trees") with most of its woody tissue growing buried deep within the sand and its flowering parts just above ground level.[13][14]
