Characteristics

Annual, with a shortly erect stem, up to 7·5(–9) dm. tall, and long decumbent lower branches.. Stem hirsute with spreading hairs.. Leaves 3-foliolate; leaflets very variable, linear-lanceolate to elliptic or obovate, with those of the leading shoot often longer and narrower, 25–75(–115) mm. long, 12–21 mm. wide, conspicuously pilose on both surfaces; petiole up to 7 mm. long.. Stipules filiform, up to 3–4 mm. long.. Racemes shortly pedunculate, up to 3–17 cm. long, with many crowded flowers; bracts filiform, up to 4 mm. long; bracteoles inserted at the base of the calyx, similar to the bract.. Calyx becoming basally truncate and deflexed against the pedicel, 3–4·5 mm. long, subglabrous except for scattered bristly hairs along the lobe-margins; lobes acuminately triangular, a little longer than the tube.. Standard suborbicular, pale yellow, purplish veined, glabrous outside; wings usually shorter than the keel; keel rounded about the middle, with a sharp slightly projecting untwisted beak, 6·5–8·5 mm. long.. Pod sessile, subcylindrical, somewhat pointed, 16–18(–20) mm. long, densely covered with long brown spreading hairs over a furry tomentum, ± 20-seeded.. Seeds oblique-cordiform, ±2·5 mm. long, smooth, pale greenish-buff, mottled greyish-mauve.

An annual shrub. The lower branches hang down. The leaves have short leaf stalks. The leaves are compound with 3 leaflets. The leaflets are 3-8 cm long by 1-3 cm wide. They are narrowly oval. The flowering stalks are short and at the top of the plant. They are 3-17 cm long with many flowers. The flowers are pale yellow with purple veins. The pod does not have a stalk. The pod is 2 cm long and cylinder shaped but with a pint. It is covered with brown hairs. There are about 20 seeds. The seeds are 2.5 mm long.
