Notes
Subsp. cajanifoliahas the surface of the leaflets clearly visible between the sparse covering of stiff hairs and slightly smaller flowers, the calyx 6–8 mm long. It occurs further south in the North-West, Gauteng and Mpumalanga Provinces of South Africa, with some intermediates in the Groblersdal and Lydenburg area. The Zimbabwean specimens from Shurugwi tend to have relatively sparse indumentum for subsp. cryptantha, but in general the differences have a distinct geographical bias.
