    Habit
    Annual or short-lived perennial, with a short erect leading shoot and many long trailing much-divided pilose branches from the base, up to 3–7·5 dm. long.
    Leaves
    Leaves 3-foliolate; leaflets narrowly to broadly elliptic or obovate, up to 20–43 mm. long, 14–30 mm. wide, with those of the leading shoot up to 53 mm. long and proportionally narrower, glabrous or sparsely pilose above, appressed pilose beneath; petiole up to 8–32 mm. long.
    Stipules
    Stipules linear-subulate, 1–3 mm. long.
    Inflorescences
    Racemes subumbelliform, usually longer than the opposed leaf, (2·5–)4–11 cm. long, usually ± 2–4-flowered (up to 8-flowered in southern Africa); bracts linear or filiform, 1–1·5 mm. long; bracteoles inserted at the top of the pedicel, filiform, up to 1 mm. long.
    Calyx
    Calyx shorter than the corolla, (4·5–)6–8 mm. long, pubescent or shortly pilose; lobes subulate, 1·7–3 times as long as the tube.
    Corolla
    Standard suborbicularor obovate, yellow, veined brown and glabrous outside; wings shorter than the keel; keel bent at right-angles in the lower third, with a long straight tapered untwisted beak, 7–12 mm. long.
    Fruits
    Pod subsessile, discoidal to shortly ellipsoid or even subglobose, but usually distinctly laterally compressed at least when young, 7–12 mm. long, 3·5–6 mm. across, 6–9 mm. in dorsiventral diameter, thick-walled and tardily dehiscent, usually rugose with the vein-network impressed to slightly raised, shortly and conspicuously pubescent, 1–3-seeded.
    Seeds
    Seeds suborbicular, up to 4 mm. across, slightly rugulose, brown.
    Habitat
    Brachystegia and derived secondary woodland (more rarely and atypical in wooded grassland of U1), on sandy soils, persisting on roadsides and cultivated ground; 250–1350 m.

    Seeds
    Seeds c. 4 mm across, subcircular, slightly rugulose, brown.
    Habit

    Leaves
    Leaves 3-foliolate; leaflets mostly 2–4.5 × 1.2–3 cm, elliptic or obovate, with those of the leading shoot sometimes up to 7 cm long and relatively narrow, appressed pilose beneath; petiole 0.8–4 cm long; stipules 1–4(8) mm long, linear-subulate.
    Inflorescences
    Racemes leaf-opposed, subumbelliform, usually longer than the opposed leaf, (2.5)4–14 cm long, 2–8-flowered; bracts 1–2 mm long, linear-subulate; bracteoles inserted at the top of the pedicel, small.
    Calyx
    Calyx (4.5)6–8 mm long, pubescent or shortly pilose; lobes triangular-subulate, 1.7–3 times as long as the tube.
