Erect shrubby herb, often an annual, 0.5–2(?4.5) m tall.

Morphology Stem

Stems covered with tubercular-based hairs.

Morphology Leaves

Leaves sensitive, 18–56-foliolate; leaflets 3–16 × 1–2.5 mm, linear-oblong, rounded at the apex, obliquely rounded at the base, finely serrulate, ± ciliate but otherwise glabrous; reticulation scarcely evident; petiole and rhachis together 2.5–8 cm long, hairy like the stems; petiolules 0.5 mm long; stipules straight, spurred, 3–8 × 1–2 mm, ovate-lanceolate, finally deciduous.

Morphology Reproductive morphology Flowers

Calyx with tubercular-based hairs, 2-lipped; lips 6–7(12) × 2.5–4 mm, one wider than the other.

Morphology Reproductive morphology Flowers Corolla

Standard white to yellow, sometimes with dark veins, 6–22 × 4–18 mm, obovate, emarginate; keel petals paler greenish-yellow with margins partly laciniate.

Morphology Reproductive morphology Fruits

Fruit stipitate, 3–5.5 cm long (excluding stipe), linear, straight or slightly curved, 4–9-jointed, the suture somewhat constricted between the articles; articles 4–5.5 mm long and wide, oblong, mostly compressed, sparsely pilose, a central oblong-elliptic part slightly thickened, densely and finely tuberculate when adult or sometimes this area inflated and longitudinally crested.

Morphology Reproductive morphology Seeds
