Morphology General Habit: Erect annual 10–70(100) cm tall, developing numerous curved-ascending branches, particularly from near the base, densely covered with long mostly spreading hairs.
Morphology Leaves: Leaves almost all 3-foliolate, uppermost sometimes 1-foliolate, crowded and larger just below the inflorescences; leaflets mostly 15–30 × 4–6 mm, upper ones up to 50 × 8 mm, linear-oblanceolate to oblong-oblanceolate, rounded at the apex, long-cuneate to the base, pilose on both surfaces; petioles mostly 5–15 mm long, uppermost up to 2.5 cm, narrowly winged; stipules 0.
Morphology Reproductive morphology Flowers: Flowers in dense subsessile heads or racemes; bracts 1–2 mm long, setaceous; pedicel recurved near apex, without bracteoles.
Morphology Reproductive morphology Flowers Calyx: Calyx 3–4 mm long, densely hairy; lobes narrowly triangular, 2–3 times as long as the tube.
Morphology Reproductive morphology Flowers Corolla: Standard obovate, pale yellow, marked red at the base inside, veined reddish and medially pubescent outside; wings nearly as long as the keel; keel 4–5.5 mm long, angular, with a narrow twisted beak.
Morphology Reproductive morphology Fruits: Pod sessile, (4)5–6 × 3–5 mm, ovoid-globose to bluntly ellipsoid, densely pilose outside, hairy inside along upper suture behind the placenta, 2-seeded.
Morphology Reproductive morphology Seeds: Seeds 2–2.5 mm long, oblique-cordiform, smooth.

Morphology General Habit: Erect annual, up to 3–7(–10) dm. tall, developing numerous curved-ascending branches particularly from near the base.
Morphology Stem: Stem densely hirsute with mostly spreading tawny hairs.
Morphology Leaves: Leaves 3-foliolate; leaflets linear-oblanceolate to oblanceolate-oblong, mostly up to 15–30 mm. long and 4–6 mm. wide, but the upper ones opposing and just below the inflorescences often larger, up to 50 mm. long and 8 mm. wide, rounded at the apex, long-cuneate, pilose on both surfaces with generally appressed hairs; petiole ± 6–15 mm. long, the uppermost up to 25 mm. long.
Morphology Leaves Stipules: Stipules absent.
Morphology Reproductive morphology Inflorescences: Inflorescences sessile dense racemes or heads, crowded at the top of the shoots surrounded by the larger spreading leaves, many-flowered; bracts filiform, 1–2 mm. long; bracteoles obscure.
Morphology Reproductive morphology Flowers Calyx: Calyx 3–4 mm. long, with the tube protracted on the lower side, densely hairy; upper lobes subulate-triangular, ± twice as long as the tube.
Morphology Reproductive morphology Flowers Corolla: Standard obovate-orbicular, pale yellow, marked red at the base inside, veined reddish and pubescent outside; wings nearly as long as the keel; keel bent at right-angles in the lower third, with a narrow twisted beak, 4–5·5 mm. long.
Morphology Reproductive morphology Fruits: Pod sessile, subglobose to ellipsoid, 5–6 mm. long, densely pilose, 2-seeded.
Morphology Reproductive morphology Seeds: Seeds oblique-cordiform, ± 2–2·5 mm. long, without a prominent aril, smooth, brown.
