Leguminosae, various authors. Flora Zambesiaca 3:7. 2003

Morphology General Habit

Stems several from a woody rootstock, erect to 60 cm, developing numerous progressively shortened flowering branches above, ribbed, densely strigulose.

Morphology Leaves

Leaves mostly 3-foliolate, uppermost reduced, some 1-foliolate; leaflets 8–15 × 2–8 mm, oblanceolate to obovate, rounded, truncate or emarginate, glabrous or nearly so above, densely white strigulose beneath; petiole 3–10 mm, slender, slightly grooved; stipules 0.

Morphology Reproductive morphology Inflorescences

Primary racemes short, few-flowered, most of the flowers on lateral branches progressively abbreviated upwards and in the axils, forming a leafy pseudopanicle; bracts 0.5–1.5 mm long, linear-subulate; bracteoles usually on the pedicel, setaceous.

Morphology Reproductive morphology Flowers Calyx

Calyx 4–5 mm long, densely strigulose; lobes triangular, somewhat acuminate or attenuate, 1.5–2 times as long as the tube.

Morphology Reproductive morphology Flowers Corolla

Standard elliptic-obovate to broadly elliptic, yellow tinged red, sparsely hairy outside; wings equalling the keel or shorter; keel 9–11 mm long, angular, with a narrow twisted beak incurved at the tip.

Morphology Reproductive morphology Fruits

Pod subsessile, 6 × 5 mm, ovoid-globose, 2-seeded (ovules 4–8).
