Morphology General Habit
Generally low rather bushy annual, decumbent or spreading and erect, much branched particularly from near the base, up to 7(–13) dm. tall.
Morphology Stem
Stem slender, slightly ribbed, thinly appressed puberulous.
Morphology Leaves
Leaves 3-foliolate; leaflets broadly oblanceolate to elliptic-obovate, rarely oblong-lanceolate, up to 14–32 mm. long, 6–14 mm. wide, glabrous above, appressed puberulous beneath; petiole up to 10–23 mm. long.
Morphology Leaves Stipules
Stipules linear, up to 1·5–4 mm. long.
Morphology Reproductive morphology Inflorescences
Racemes up to 10–20 cm. long, with generally numerous fairly closely arranged flowers; bracts linear, ± 1–2(–3) mm. long; bracteoles inserted on the pedicel, inconspicuous.
Morphology Reproductive morphology Flowers Calyx
Calyx 3–4 mm. long, protracted on the lower side, appressed puberulous; upper lobes triangular and slightly acuminate, scarcely longer than the tube, rarely narrowly triangular and longer.
Morphology Reproductive morphology Flowers Corolla
Standard broadly elliptic-obovate, yellow, veined brown, usually puberulous outside, at least along the midvein; wings nearly as long as the keel; keel bent at right-angles in the lower half, with a narrow practically straight twisted beak, 7–10 mm. long.
Morphology Reproductive morphology Fruits
Pod oblong-clavate, narrowed towards the base into the very short 1–2 mm. long stipe, 14–22 mm. long, 5–8 mm. across, appressed puberulous, ± 10–25-seeded.
Morphology Reproductive morphology Seeds
Seeds bluntly triangular in outline, ± 2–2·5 mm. long, rugulose, brown.
