Characteristics

Erect bushy and slightly woody perennial, up to 1 m. tall.. Stem terete to finely ribbed above, densely pubescent or pilose with both appressed and rather spreading hairs.. 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.. Stipules oblong-falcate, up to 8–18 mm. long, 2·5–7 mm. wide, acuminate, markedly unequal-sided.. 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.. Calyx (5·5–)8–10 mm. long, rather densely pubescent with appressed or slightly spreading hairs; lobes triangular, a little longer than the tube.. 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.. Pod sessile, shortly and broadly cylindrical, at least 22 mm. long, densely spreading tomentose, ± 12–16-seeded.. Mature seeds unknown.
