An ascending (or decumbent) shrublet usually 0.3-1 m tall, sparingly branched, with rather long, tail-like, erect or bending, densely leafy branches. Young branches short-and white-villous. Short-shoots on pubescent, semiglobose tubercles. Leaflets linear-filiform, (5-)8-18 mm long and ±0.5 mm thick, ± incurved and weak (not very prickly), green, glabrous (or with sparse hairs on the base), acuminate. Inflorescences unifloral, on lateral short-shoots, distributed on often long parts (up to 0.2 m or more) of the branch ends. Bract subulate, 0.7-1.2(-1.6) mm long, ciliate, otherwise glabrous. Pedicel very short (less than 0.5 mm). Bracteoles usually lacking, when present then small, subulate, almost concealed in the pubescence of calyx base. Calyx tube campanulate-cylindrical, 3.5-4 mm long, often short-tomentose on base and on distal half, sometimes quite glabrous; lobes shortly deltoid to narrowly triangular, 0.5-1(-1.2) mm, acute, ± convex, glabrous or subglabrous. Petals light yellow, wing and keel petals with claws as long as blades. Standard blade broadly ovate, 4.1-5.3 x 5-6 mm, obtuse-refuse, basally cordate-auriculate, tomentose on apical third. Wing blades 3.6-4.5 x 1.4-2.1 mm, glabrous, with several rows of minute folds on basal half. Keel blades lunate, 3.2-3.9 x 1.6-2.3 mm, glabrous, obtuse, with slightly convex upper margin. Pistil long-hairy on upper part (most) of ovary and on style base; ovules 2. Pod narrowly and obliquely ovate, 6.8-8.6 x 3-3.7 mm, densely sericeous or woolly.
