Similar to C. alexandri, but with generally shorter hairs (0.1–0.3 mm long), the leaflets variable but often more wedge-shaped, broadest near the apex, subacute to rounded or often truncate, glabrous or shortly pubescent above, bracts much shorter than the pedicel, 0.5–1.5 mm long, and the pod 2-seeded.
Seeds sometimes (Mbala region) with an aril.
