Morphology General Habit
Erect bushy and slightly woody perennial, up to 1 m. tall.
Morphology Stem
Stem terete to finely ribbed above, densely pubescent or pilose with both appressed and rather spreading hairs.
Morphology Leaves
Leaves 3-foliolate; leaflets narrowly oblong or oblanceolate, up to 30–52 mm. long, 6–14 mm. wide, more rarely elliptic, up to 55 mm. long, 24 mm. wide, glabrous above, densely appressed pubescent or pilose beneath; petiole 14–35 mm. long.
Morphology Leaves Stipules
Stipules oblong-falcate, up to 8–18 mm. long, 2·5–7 mm. wide, acuminate, markedly unequal-sided.
Morphology Reproductive morphology Inflorescences
Racemes lax, up to 10 cm. long, ± 6–15-flowered; bracts subulate or linear, 3–9 mm. long, early caducous; bracteoles inserted on the upper part of the pedicel, filiform, 3·5–6·5 mm. long, caducous.
Morphology Reproductive morphology Flowers Calyx
Calyx (5·5–)8–10 mm. long, rather densely pubescent with appressed or slightly spreading hairs; lobes triangular, a little longer than the tube.
Morphology Reproductive morphology Flowers Corolla
Standard suborbicular, bright yellow, sometimes faintly lined with brown, glabrous outside; wings oblanceolate to broadly obovate-oblong, longer than the keel; keel abruptly angled in the lower half, with a straight blunt untwisted beak, 14–16 mm. long, densely white lanate-pilose towards the upper margin.
Morphology Reproductive morphology Fruits
Pod sessile, shortly and broadly cylindrical, at least 22 mm. long, densely spreading tomentose, ± 12–16-seeded.
Morphology Reproductive morphology Seeds
Mature seeds unknown.
Habitat
Deciduous woodland, particularly in secondary growth and margins, grassland of seasonally inundated places, also persisting on roadsides; 1200–2450 m.
