An (decumbent-)ascending or erect shrublet 0.2-0.6 m tall, with rather thick, sparingly ramified branches closely short-and white-woolly on the young parts, with semiglobose short-shoot tubercles. Leaflets linear-subulate, needle-like, 2-6 (generally ±4) mm long, ±0.35 mm thick, subterete, acute, ± incurved, glabrous, pale green. Inflorescences unifloral, on lateral short-shoots, few to numerous on each branch. Bract small, subulate-filiform, 0.7-2.2 x 0.1-0.2 mm, acute, ± puberulous. Pedicel 0.5-1 mm long, densely tomentose. Bracteoles minute, 0.1-0.3 mm. Calyx tube campanulate, densely short-tomentose; lobes sharply demarcated, subulate (leaflet-like), (1.2-)1.7-2.5(-3) mm long, glabrous or subglabrous, green, pointed, slightly incurved. Petals pale or light yellow. Standard blade broadly ovate-circular, (4.6-)5-6.2 x (4-)4.5-6.5 mm, subacute, often ending as a short 'tip', generally short-tomentose on the apical parts of the back, otherwise glabrous. Wing blades 3.7-4.5 x 1.7-2.1 mm. Keel blades (3.8-)4.2-4.7 x 1.8-2.4 mm, upper margin S-curved or concave. Pistil tomentose on ovary and ciliate above on basal third of style. Pod obliquely ovate, 4.8-5.2 x 2.5-3.2 mm, sparsely tomentose to partly sericeous (not woolly).
