Characteristics

Perennial with numerous erect simple or little-branched stems from a narrow sometimes rhizomatous stock, up to 1–3·5 dm. tall.. Stems very slender, generally rather densely covered with appressed hairs.. Leaves mostly 3-foliolate, but the uppermost usually 1-foliolate; leaflets linear-oblanceolate to oblanceolate, up to 9–14 mm. long and 1–3·5 mm. wide, acute to rounded at the apex, often folded lengthwise, glabrous or with a few scattered hairs above, appressed pilose beneath; petiole ± 1–3 mm. long.. Stipules absent.. Racemes sessile or shortly pedunculate, up to5–13 cm. long, with a number of fairly closely arranged flowers and other flowers often clustered in the axils below; bracts linear to linear-lanceolate, 1–3(–5) mm. long; bracteoles variously inserted on the pedicel or rarely at the base of the calyx, filiform, 0·5–1(–2·5) mm. long.. Calyx 3·5–4·5 mm. long, with the tube slightly protracted on the lower side, densely appressed pubescent; upper lobes acuminately triangular, at least a little longer than the tube.. Standard obovate-orbicular, yellow, heavily flushed maroon-brown or purple, glabrous to thinly pubescent outside; wings scarcely shorter than the keel; keel bent at right-angles in the lower third, with a narrow twisted beak slightly incurved at the tip, 5·5–7(–8) mm. long.. Pod sessile, ovoid-globose to shortly ellipsoid, pointed, up to 5–7 mm. long and 3–4 mm. across, appressed pubescent, ± 3–6-seeded.. Seeds orbicular-cordiform, up to 2 mm. across, without a conspicuous aril, smooth, purplish-brown.
More
Leaves often little developed at flowering time, mostly 3-foliolate, uppermost often 1-foliolate; leaflets 4–14 × 0.5–3(4) mm, linear-oblanceolate to oblanceolate, acute to obtuse or rarely rounded at the apex, often folded lengthwise, glabrous or nearly so above, finely pubescent beneath; petiole 1–3(10) mm long, channelled; stipules 0.
Standard broadly elliptic-obovate, yellow, usually flushed crimson-purple, usually thinly but extensively pubescent outside; wings ± as long as the keel; keel 5–7 mm long, angular, with a narrow twisted beak slightly incurved at the tip.
Racemes (3)7–12 cm long, subdense at first, becoming lax, (6)10–24-flowered, often with flowers in the axils below; bracts 1–3(6) mm long, linear-lanceolate, usually shorter than the pedicel; bracteoles on the pedicel, setaceous.
Stems several to many, erect from a slender vertical and rhizomatous rootstock, 8–35 cm tall, slender, simple to sparingly branched, scarcely ribbed, appressed or subappressed pubescent.
Calyx 3–4 mm long, appressed pubescent; lobes triangular to triangular-lanceolate, 1.2–1.5(2) times as long as the tube.
Pod nearly sessile, 5–7 × 3–4 mm, ovoid-globose to shortly oblong-ovoid, appressed pubescent, 4–10-seeded.
Seeds c. 2 mm long, rounded-cordiform, smooth, brown, exarillate.
