A herb or small shrub. It keeps growing from year to year. It has several stems coming from a woody rootstock. It grows up to 1.2 m tall. There are several short flowering branches. The branches are ribbed and they have hairs. The leaves mostly have 3 leaflets. The leaflets are 5-22 mm long by 2-10 mm wide. There are 6-10 flowers in a group. The fruit are pods 6-8 mm long by 4-6 mm wide. They have 2 seeds. The seeds are 2 mm long.
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.
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.
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.
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.
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).
Pods subsessile, 6–8 × 4–6 mm, ovoid-globose, pointed, strigose-puberulent, 2-seeded.
Seeds 2–2.5 mm long, rounded-cordiform, smooth, dark, with a small aril.
