    Habit
    Subshrub, several-stemmed from a woody rootstock, (0.1)0.5–1.2 m tall, developing numerous shortish flowering branches above; plants smelling of honey when dried; branches ribbed, densely strigulose with frequently brown-based hairs, sometimes with slightly longer hairs interspersed.
    Leaves
    Leaves mostly 3-foliolate, uppermost sometimes 1-foliolate; leaflets 5–22 × 2–10 mm, oblong-oblanceolate to oblong-obovate or obovate, slightly coriaceous, densely strigulose or strigose-puberulent beneath; petiole 3–15(20) mm long, channelled; stipules 0.
    Inflorescences
    Primary racemes 2–5 cm long, ± laxly 6–10-flowered, with numerous shorter inflorescences developed on lateral branches and in the axils; bracts 1–3 mm long, linear-lanceolate, usually shorter than the pedicel; bracteoles on the pedicel or calyx, 0.5–4 mm long.
    Calyx
    Calyx 4–5 mm long, densely strigulose or strigose-puberulent; lobes acuminately or attenuately triangular, 0.8–2 times as long as the tube, often slightly involute, ± lanate inside (particularly the lower one).
    Corolla
    Standard elliptic-obovate to obovate, yellow, sometimes lined brown, glabrous or nearly so outside; wings as long as the keel or a little shorter; keel 8–11 mm long, angular, with a narrow twisted beak, slightly incurved at the tip.
    Fruits
    Pods subsessile, 6–8 × 4–6 mm, ovoid-globose, pointed, strigose-puberulent, 2-seeded.
    Seeds
    Seeds 2–2.5 mm long, rounded-cordiform, smooth, dark, with a small aril.

    Habit
    Erect rather bushy perennial herb or suffrutex, generally with several stems from the woody rootstock, up to 5–12 dm. tall, usually with many short almost leafless flowering branchlets towards the top.
    Stem
    Stems distinctly ribbed, appressed puberulous to densely spreading pubescent.
    Leaves
    Leaves 3-foliolate or sometimes with the uppermost 1-foliolate; leaflets oblanceolate to oblong-elliptic or obovate, up to 8–27 mm. long and 3–11 mm. wide, mostly rounded or retuse at the apex, ± subcoriaceous, glabrous or with scattered hairs above, appressed puberulous or pubescent beneath; petiole broadly grooved or narrowly winged, ± 2–12(–17) mm. long.
    Stipules
    Stipules absent.
    Inflorescences
    Racemes terminal, somewhat lax, rather short, ± 2–8 cm. long, ± few-flowered, sometimes compound, always with other short almost leafless flowering shoots or clusters of flowers from many of the axils below; bracts lanceolate, ± 2–3(–4) mm. long; bracteoles variously inserted, linear or filiform, ± 0·5–4 mm. long.
    Calyx
    Calyx 3·5–6 mm. long, with the tube protracted on the lower side, densely appressed puberulous, sometimes with hairs dark brown at the base; upper lobes attenuate-triangular to narrowly deltoid, ± markedly acuminate, shorter to longer than the tube.
    Corolla
    Standard elliptic-obovate, yellow, often lined or flushed reddish-brown outside, glabrous or with a few hairs at the apex outside; wings shorter than the keel; keel bent at right-angles in the lower third, with a long narrow twisted beak slightly incurved at the very tip, (8–)9–11(–12) mm. long.
    Fruits
    Pod sessile, ovoid, slightly compressed laterally, 6–7 mm. long, 5–6 mm. in dorsiventral diameter, appressed puberulous or pubescent, 1–2-seeded.
