Morphology General Habit

Erect laxly branched annual or short-lived perennial, 0.2–1.7 m tall; branches mostly ascending, lower ones sometimes spreading, ribbed, covered at least when young with short appressed or rarely slightly spreading hairs.

Morphology Leaves

Leaves 3-foliolate (rarely a few of the uppermost 1-foliolate), estipulate; leaflets mostly 4–11(17) × 0.3–2(3.5) cm, usually predominantly linear-lanceolate to lanceolate, the lower ones sometimes elliptic, but sometimes (particularly subsp. exigua) all elliptic-oblong to elliptic, thinly appressed puberulous beneath, rarely also above; petiole shorter than the leaflets.

Morphology Reproductive morphology Inflorescences

Racemes up to 8–35 cm long, many-flowered; bracts 0.5–3 mm long, subulate or filiform, expanded at the base; bracteoles at the base of the calyx, 0.3–1 mm long.

Morphology Reproductive morphology Flowers Calyx

Calyx 2–4 mm long, becoming basally truncate and deflexed against the pedicel, puberulous; lobes subulate to triangular-acuminate, usually shorter than the tube.

Morphology Reproductive morphology Flowers Corolla
