Information
Perennial, with a woody rootstock. Stem scabrous or pubescent. Leaflets lobed. Peduncle 1–2 mm wide; rhachis 0.5–3 cm long, 3–10-noded, internodes 1–5 mm long. Flower strongly aromatic, 16–21 mm long. Calyx lobes 3–5 mm long. Keel without a beak, twisted towards the left (while looking at the keel from the standard). Ovary 9–14-ovuled. Pod scabrous within the Flora Zambesiaca area (can be pubescent in South Africa).
Habitat
Mainly on Kalahari Sand in the Flora area, often associated with Terminalia sericea
Range
in South Africa from Northern Province to the eastern coastal area of Eastern Cape Province. No specimens have been seen from Angola although the taxon would be expected to occur there.

Notes
One could consider three groups within this subspecies, with intermediate specimens between them in the areas where their distributions overlap. The first group would include stout specimens from dry areas of Namibia, Botswana and western parts of the former Transvaal, in which the plants are scabrous or poorly pubescent with scabrous pods. The second group would include specimens from eastern parts of the former Transvaal and Cape Province of South Africa in which the plants are stout and pubescent often with pubescent pods. The third group would include specimens from the Transvaal in which the plants are more slender and possess linear leaflets and scabrous pods. In addition to the above a further 5 subspecies are recognised, all occurring to the north of the Flora Zambesiaca area.
