Characteristics

Ascending to spreading shrublet, up to ?0.2 m (exact height unknown). Branches densely pilose to glabrescent, with golden sessile glands scattered on the surface. Stipules ovate, pilose and glandular on both surfaces, 1-2 mm long. Leaves alternate, pinnately trifoliolate; petiole 2-6 mm long, pilose and glandular; leaflets conspicuously reticulate-veined on both surfaces, adaxial surface pilose, abaxial surface pilose along midrib, intervenal areas scattered with small, raised, golden glands, adaxial surface dark green, abaxial surface light green, margins entire, slightly thickened and often slightly revolute; terminal leaflets narrowly oblong to oblong, 5-10 x 2-4 mm, mucronate; lateral leaflets narrowly oblong to oblong, 4-8 x 2-3 mm, mucronate. Inflorescence an axillary raceme, ±15-40 mm long, 1 or 2-flowered, peduncle slender, longer than leaves; pedicels 1.0-1.5 mm long, pilose, scattered glands present; bract ovate, 1.5-2.5 mm long, pilose with scattered glands on adaxial surface, caducous; bracteoles absent. Flowers 6-8 mm long, yellow. Calyx ±6-8 mm long, pilose with glands on the adaxial surface, subequally lobed; tube ±1.5-2.0 mm long; lobes subulate, ±4.0-6.5 mm long, upper two lobes fused slightly higher up than lower three lobes, carinal lobe longer than the others. Standard 7-9 mm long, claw linear, ±1 mm long; lamina elliptic, 5-6 x 3-4 mm, apex truncate, glabrous. Wings 6-7 mm long, claw 2.0-2.5 mm long; lamina oblong, ± as long as the keel, 5.0-5.5 x 1.0-1.5 mm, apex obtuse, glabrous, without sculpturing. Keel 6-7 mm long, claw 2.0-2.5 mm long; lamina oblong, 5.0-5.5 x 2.5-3.0 mm, apex obtuse, glabrous, pocket present. Stamens diadelphous, 9+1, anthers monomorphic. Pistil shortly stipitate, stipe 0.5-1.0 mm, pilose, scattered glands present, ovary elliptic, 1.5-2.0 x ±0.5 mm with 2 ovules; style ±5-6 mm long, curved upwards, glabrous. Pods shortly stipitate, broadly oblong, laterally compressed, 10-11 mm x 4-6 mm, pilose, glands present (especially along the margins) to glabrescent, 1 to 2-seeded, ?dehiscent (as the plant was not seen in the field this is not certain). Seeds not seen. Flowering and fruiting time: December (there are only two specimens available, both collected in December).
