    Habit
    Erect annual, 30–70 cm tall, developing ascending branches from the base and ultimately many short flowering branches near the top; stem slender, appressed pubescent.
    Leaves
    Leaves mostly 3-foliolate, the upper ones 1-foliolate; leaflets 10–30 × 2–10 mm, mostly linear-oblanceolate to oblong-oblanceolate, the lower ones sometimes more obovate, glabrous or nearly so above, finely appressed pubescent beneath; petiole 4–20 mm long; stipules 0.
    Inflorescences
    Racemes 6–15(30) cm long, lax or upper part dense, main ones 16–40-flowered, other short racemes and clusters of flowers in the axils below; bracts 2–3 mm long, linear, shorter than the pedicel; bracteoles on upper part of the pedicel, setaceous.
    Calyx
    Calyx 4–5 mm long, appressed pubescent; upper lobes attenuate-triangular, c. 2–3 times as long as the tube.
    Corolla
    Standard elliptic-obovate, yellow, often veined reddish-brown, pubescent medially and apically outside; wings shorter than the keel; keel 8–11 mm long, angular, with a narrow twisted beak, slightly incurved at the tip.
    Fruits
    Pods subsessile, 4–6 × 4 mm, subglobose-ovoid, slightly pointed, appressed pubescent, 2-seeded.
    Seeds

    Stem
    Stem slender, shortly appressed pubescent.
    Leaves
    Leaves mostly 3-foliolate, the upper ones 1-foliolate; leaflets oblanceolate to oblong-oblanceolate, the lower ones sometimes obovate, up to 18–30 mm. long and 3–8 mm. wide, obtuse to rounded or truncate at the apex, glabrous or with a few small scattered hairs above, finely appressed pubescent beneath; petiole ± 4–20 mm. long.
    Stipules
    Stipules absent.
    Inflorescences
    Racemes mostly pedunculate, lax to rather dense, many-flowered, and usually with other short racemes or clusters of flowers in the axils below; bracts linear, 2–3 mm. long, shorter than the pedicel; bracteoles inserted on the upper part of the pedicel, filiform, 0·5–1·5 mm. long.
    Calyx
    Calyx 4–5 mm. long, with the tube protracted on the lower side, rather shortly appressed pubescent; upper lobes subulate-triangular, ± 2–3 times as long as the tube.
    Corolla
    Standard elliptic-obovate, yellow, often veined brown outside, pubescent medially and apically outside; wings much shorter than the keel; keel bent at right-angles in the lower quarter, with a long very narrow twisted beak, slightly incurved at the tip, 8–11 mm. long.
    Fruits
    Pod subsessile, subglobose-ovoid, slightly pointed, up to 4–5 mm. long, appressed pubescent, 2-seeded.
    Seeds
    Seeds suborbicular-cordiform, ± 2 mm. across, with a prominent aril, smooth, brown.
