Morphology General Habit
Stems several to many, erect from a napiform and/or rhizomatous rootstock, 10–70(100) cm tall, simple to sparsely branched, finely ribbed, appressed puberulous to spreading pubescent.
Morphology Leaves
Leaves all or almost all 3-foliolate, uppermost occasionally reduced, 1-foliolate; leaflets 8–45 × 2–17 mm, mostly oblanceolate, but varying from linear-oblanceolate to elliptic-obovate, appressed puberulous to pubescent beneath; petiole 0.2–2.5 cm long, broadly channelled to distinctly winged; stipules 0.
Morphology Reproductive morphology Inflorescences
Racemes sessile to shortly pedunculate, 1–17 cm long, densely to laxly 15–40-flowered, sometimes with flowers or flowering branches from upper axils; bracts 1.5–4 mm long, linear-lanceolate, shorter to longer than the pedicel; bracteoles inserted on the pedicel, 0.5–1.5 mm long, setaceous.
Morphology Reproductive morphology Flowers Calyx
Calyx 3–5 mm long, thinly to densely pubescent with appressed to rather irregularly arranged hairs; lobes narrowly triangular and slightly acuminate, rarely subulate with inrolled margins, (1)1.2–1.5(2) times as long as the tube.
Morphology Reproductive morphology Flowers Corolla
Standard elliptic or elliptic-obovate to subcircular, yellow, sometimes lined or flushed reddish, glabrous outside in the Flora Zambesiaca area; wings ± as long as the keel; keel 6–10 mm long, angular, with a narrow twisted beak.
Morphology Reproductive morphology Fruits
Pod sessile, 5–7 × 4–5.5 mm, ovoid-globular, appressed puberulous to glabrous except on upper side, 2–8-seeded.
Morphology Reproductive morphology Seeds
Seeds 2–2.5 mm long, rounded-cordiform, smooth, brown, exarillate.
