    Habit
    Decumbent to erect annual or short-lived perennial, up to 1.8 m tall; branches subappressed pubescent to spreading hirsute.
    Leaves
    Leaves 3-foliolate, sometimes mostly on short shoots; leaflets 4–50 × 2–15 mm, linear or oblanceolate to elliptic-oblong or obovate, hairy on both surfaces or only beneath; petiole 2–30 mm long; stipules 1–3 mm long, subulate to attenuate-triangular.
    Inflorescences
    Racemes usually of two sorts; primary racemes terminal or leaf-opposed on long shoots, 2–40 cm long, laxly 3–40-flowered, indeterminate (ending in a bud) or determinate (ending in a bristle-like extension of the rhachis); supplementary inflorescences usually developed (at least later in the season) from short shoots in axils of the main leaves, with 1–2 flowers on a filiform axis 0.2–2.5 cm long; bracts 0.5–4 mm long, linear-subulate to linear-lanceolate, usually shorter than the pedicel; bracteoles on the pedicel, setaceous.
    Calyx
    Calyx 3.5–9 mm long, pubescent; lobes narrowly attenuate-triangular (rarely somewhat oblong and apiculate in subsp. pauciflora), 1.5–2.5 times as long as the tube, lanate along the inner margins (particularly of the lower lobes) when young.
    Corolla
    Standard broadly elliptic, yellow, often lined red, pubescent or rarely almost glabrous outside; wings broadened upwards, nearly as long as the keel; keel 6–12(14) mm long, angular, with a narrow twisted beak.
    Fruits
    Pod shortly stipitate, 8–15 × 5–9 mm, ± oblong-obovoid (sometimes only slightly broadened apically), pubescent outside and sometimes also inside, 6–10(12)-seeded.
    Seeds
    Seeds 2.2–3 mm long, oblique-cordiform, smooth, brown.

    Habit
    Erect or rather spreading annual or short-lived perennial, up to 5–17 dm. tall, variably branched.
    Stem
    Stem subappressed pubescent with fine rather irregularly arranged white hairs, rarely spreading and dense.
    Leaves
    Leaves mostly crowded on very short axillary shoots, appearing fasciculate, 3-foliolate; leaflets linear-oblanceolate to oblanceolate or oblong-lanceolate, rarely obovate, up to 10–25 mm. long, 2–8 mm. wide, glabrous or pubescent above, pubescent beneath; petiole slender, ± 3–8 mm. long.
    Stipules
    Stipules filiform or linear-subulate, up to 1–2 mm. long.
    Inflorescences
    Inflorescences usually both lax terminal or leaf-opposed racemes, up to 6–22 cm. long, with a number of flowers, and also short slender axes apparently axillary from the leaf-clusters, with up to 1–4 flowers, up to ± 2 cm. long; bracts linear to linear-lanceolate, 1–3 mm. long, shorter than the pedicel; bracteoles inserted on the pedicel, filiform, small.
    Calyx
    Calyx 5–7(–8) mm. long, with the tube protracted on the lower side, appressed pubescent; upper lobes narrowly attenuate-triangular, much longer than the tube.
    Corolla
    Standard broadly elliptic to obovate or suborbicular, yellow, veined reddish-brown, densely pubescent outside; wings oblong-obovate, nearly as long as the keel; keel bent at right-angles in the lower half, with a long narrow twisted beak, 10–13 mm. long, lanate along the upper margin.
    Fruits
    Pod subsessile to shortly stipitate, shortly oblong-ellipsoid or somewhat obovoid, 11–14(–18) mm. long, 5–7 mm. across, usually rather densely subappressed pubescent outside, sometimes ± glabrescent, pubescent inside, ± 6–12(–18)-seeded.
    Seeds
    Seeds oblique-cordiform, ± 3 mm. long, smooth, brown.
    Habitat
    Brachystegia woodland and deciduous bushland, extending into upland grassland; 700–1650m.
    Distribution
    Zambia and Rhodesia to the Transvaal T4 T6 T7 T8
