Trees, mostly c. 10−20 m, but often with dwarf forms over shallow soils, plus a small number of suffrutices, rare in Zambia; bark mostly rough, smooth in a few species; leaves paripinnate, leaflets in 2-numerous pairs; though variable within species, the leaves provide the most reliable features for identifying the species; flowers in spikes or panicles, mostly terminal and axillary, occasionally on second year wood; sepals much reduced, petals rudimentary or absent; ovary pubescent but pod always glabrous; pod woody, oblong to obovate, with flanges along the top (ventral) suture. Worldwide: 30 species in tropical Africa, 13 species in the Flora Zambesiaca region, 13 species in Zambia. DRC: 6 taxa. Insects associated with this genus:
