Mounded to spreading shrubs up to 50-100(200) mm tall, resprouter. Stems erect off basal rhizomes, branched near base,5-10 mm thick, brown, bark split vertically encrusted with old urn-shaped pustules and thickened persistent stipule scars. Young shoots purplish green, hispid (mixture of short and long hairs). Flowering shoots clustered in the upper two axils of the new season's growth, densely white hispid, with large urn-shaped pustules concentrated below leaves. Leaves digitately trifoliolate. Stipules1.5-1.7 x 1.0 mm, narrowing and shortening up the shoot, scarcely fused to the base of the petiole, subulate, glabrous, margins scarcely ciliate, densely encrusted with orange glands especially at the base. Leaflets (5)7-12 x 2.5-3.0 mm, flat, veins and areoles clearly visible; oblanceolate to oblong, somewhat falcate, apex acuminate, base cuneate; mucro straight in older leaves, recurved mucronate in basal leaves; laterals glabrous, margins sparsely appressed scabrid, longer than terminal leaflet, slightly asymmetrical, glands denser on lower surface, raised; petioles 0.5-1.0 mm long, gland encrusted. Inflorescences 1 or 2 axillary, capitate, with 1 or 2 triplets of flowers; each triplet subtended by a single 4 x 2 mm, oblong, pubescent, glandular bract; pedunculate, 2-3 mm long. Flowers 10 mm long, white; pedicel2-3 mm long; bract filiform, densely hairy, 1 mm long. Calyx 9 mm long; upper four teeth equal, 5 x 2 mm, keel tooth 7 x 3 mm; vexillar teeth scarcely connate, teeth covered in small and large glands, densely white pilose outside; tube 2 mm deep. Standard 10 x 6.0 mm, blade elliptic, white with a large central 4 x 2 mm wide purple nectar guide, slightly auriculate, apex acute, appendages absent; claw 0.5 mm long. Wing petals 9 x 2.5-2.6 mm, longer than the keel, auriculate, cultrate but tips billowy and incurving, midline of blade sharply upcurved; claw 3 mm long; sculpturing upper basal, upper central and upper left distal comprised of 30-55 irregularly parallel lamellae. Keel blades7 x 4 mm, apex rounded, apex purple on inner face; claw 3 mm long. Androecium 7 mm long; vexillar stamen 6.0-6.5 mm long, attached at base only. Pistil 7 mm long; ovary 2.5 mm long, papillose, glabrous; gynophore 0.5 mm long; style glabrous, 0.5 mm thick at the point of flexure, height of curvature stigma 1.5 mm, incurved. Fruits 4 x 2 mm, glabrous, densely glandular, papery thin; seeds unknown.
