'Stalk' of the terminal leaflet longer than those of the lateral leaflets. Lateral veins forming loops inside the blade margin. Stipules persistent, narrowly triangular, about 2-4 mm long. Stipels present. Compound leaf rhachis shallowly channelled on the upper surface.

Flowers

Inflorescence up to 25 cm long, clothed in hairs. Calyx outer surface clothed in prostrate hairs. Petals: standard about 13 x 15 mm, mainly purple except for a triangular yellow patch at the base; wings obovate, about 11 mm long; keel about 11 mm long. Stamens 10.

Seedlings

Numerous (about 15) cataphylls produced before the first pair of true leaves. First three true leaves trifoliolate, subsequent leaves pinnate with five to seven leaflets. At the tenth leaf stage: leaflet blades elliptic, apex acute, base cordate, terminal leaflet larger and on a larger stalk than the lateral leaflets. Leaflets mainly glabrous except for the midrib which is hairy on both the upper and lower surfaces and raised on the upper surface. Stipules hairy, linear, about 2.5 mm long. Stipels absent.
