    Habit
    Annual or short-lived perennial, with a short erect leading shoot and long trailing much-divided spreading pubescent or pilose branches radiating from the base, up to 6 dm. or more long.
    Leaves
    Leaves 3-foliolate; leaflets narrowly to broadly elliptic or oblanceolate to obovate, up to 16–42 mm. long, 5–26 mm. wide, with those of the leading shoot up to 50–68 mm. long and proportionally narrower, glabrous or sparsely pilose above, appressed pilose beneath; petiole up to 12–34 mm. long.
    Stipules
    Stipules subulate, 1–4 mm. long.
    Inflorescences
    Racemes subumbelliform, shorter or longer than the opposed leaf, 1–9 cm. long, ± 3–8-flowered; bracts linear, up to 1·5 mm. long; bracteoles inserted at the top of the pedicel, filiform, 0·5–1 mm. long.
    Calyx
    Calyx shorter than the corolla, 3·5–4·5(–5) mm. long, pubescent; lobes subulate or narrowly deltoid, ± 1·25–2 times as long as the tube.
    Corolla
    Standard suborbicular or obovate, yellow, finely veined reddish-brown and glabrous outside; wings shorter than the keel; keel bent at right-angles in the lower third, with a long tapered untwisted beak, 4·5–6(–7·5) mm. long.
    Fruits
    Pod practically sessile, subglobose, 5–6(–7) mm. long, 4–6 mm. across, 4·5–6 mm. in dorsiventral diameter, thick-walled and tardily dehiscent, densely covered with hairs obscuring the fruit-surface, ultimately somewhat glabrescent and sometimes rugulose, but without the vein-network raised, 1–3-seeded.
    Seeds
    Seeds sub-orbicular in outline, 3–3·5 mm. across, slightly rugulose, terracotta or pale brown.
    Habitat
    Deciduous bushland and thicket, secondary scrub and persisting on roadsides, cultivated ground and waste places; 950–1350 m.

    Leaves
    Leaves 3-foliolate; leaflets mostly 1.2–4.2 × 0.5–2.5 cm, narrowly to broadly elliptic or oblanceolate to obovate, with those of the leading shoot up to 7 cm long and relatively narrow, appressed pilose at least beneath; petiole 6–35 mm long; stipules 1–6 mm long, linear-subulate.
    Inflorescences
    Racemes leaf-opposed, subumbelliform, shorter or longer than the opposed leaf, 1–9 cm long, 3–8-flowered; bracts up to 1.5 mm long, linear; bracteoles at the top of the pedicel, filiform, small.
    Calyx
