Characteristics

A slender, probably short-lived perennial or perhaps biennial. Stems decumbent to suberect, up to 0.4(1) m high, branching in the lower part; young stems appressed-or spreading-pubescent. Leaves unifoliolate; petiole c.1 mm long; lamina up to 8 x 1.5 cm, linear-oblong or linear-lanceolate, 6-10 times as long as broad, the upper surface glabrous, the lower surface appressed or spreading-pubescent; stipules triangular-linear. Flowers in groups of 1-3 in axils of foliage leaves; pedicels 1-15(17) mm long. Calyx 4-10 mm long, pubescent, the teeth long-acute, subequal, 1.5-4 times as long as the tube, the two upper ones only slightly joined at the base. Petals pink or somewhat violet, or perhaps yellow outside, equalling or exceeding the calyx; standard 7-13 mm long, broadly spathulate to obovate-cuneate; wings and keel ± equal in length, slightly shorter to about equalling the standard, with the claw about half as long as the limb. Stamen tube open dorsally. Ovary pubescent on sutures, glabrous or pubescent on surfaces; style glabrous. Pod 20(27)-40 x 3.5-5 mm, sutures pubescent, surfaces glabrous or pubescent.
