Description: "Erect or rather spreading annual or short-live perennial, up to 6-26 cm tall, simple to much branched. Stem ribbed, densely pubescent, with appressed or usually mostly slightly spreading hairs. Leaves 3-foliolate; leaflets variable, narrowly oblanceolate-oblong to obovate, up to 35-85 mm long, 8-25 mm wide, glabrous or sparsely appressed pubescent above, thinly appressed pubescent beneath; petiole up to 35-65 mm long. Stipules oblong-falcate, 9-25 mm long, 3-7 mm wide, acuminate, very unequal-sided. Racemes 4-24 cm long, with many flowers crowded at least towards the top; bracts subulate or filiform, 3-4 mm long, early caducous; bracteoles inserted on the pedicel, filiform, 1-1.5 mm long, caducous. Calyx 4-5 mm long, appressed or rather spreading pubescent especially on the lobes; lobes subulate-triangular, ± as long as the tube. Standard ovate, yellow, veined or suffused with orange, brown or purple, glabrous outside; wings oblong, a little shorter than the keel; keel bent at right-angles in the lower half, with a well-developed straight untwisted beak, 8.5-10 (-11.5) mm long, conspicuously white lanate-pubescent on the lateral surfaces towards the upper margin. Pod subsessile, oblong-ellipsoid, 15-20 mm long, 7-9 mm across, thinly pubescent with appressed or slightly spreading hairs, often mottled brown or purplish, 12-16-seeded. Seeds oblong-reniform, ± 4 mm long, with a small aril, minutely granulate, sometimes radially veined, yellow, usually tinged orange or red" (Gillett et al., 1971; pp. 875-876).
"Annual herb or shrub to 2 m tall, most parts with short flattened hairs. Leaves with 3 leaflets, prominent stipules in the axils. Flowers yellow, pea-shaped, in racemes up to 25 cm long at the end of branches. Pods inflated, maturing brown with many small orange-red seeds" (Smith, 2002; p. 59).
Habitat/ecology: "Common on disturbed sites, roadsides, overgrazed pastures and in riparian habitats. It readily invades disturbed areas and prevents the regeneration of native species" (Smith, 2002; p. 59). In east Africa, "deciduous woodland and grassland, sometimes on termite mounds, also persisting on roadsides and cultivated ground; 600-2400 m" (Gillett et al., 1971; pp. 875-876).
Propagation: "Seed is dispersed in contaminated pasture seed and fodder. Also by machinery, vehicles and water." (Smith, 2002; p. 59).
Native range: Tropical Africa (Smith, 2002; p. 59).
