A decumbent or, more often, ascending shrub up to 0.3 m tall, sparingly branched, with densely leafy branches and densely long-pubescent branches and foliage. Leaflets linear, 2.5-7 mm long, 0.3-0.4 mm thick, subterete, ± straight, weak, acute or subobtuse, pale green (to reddish), covered with dense, long, straight, spreading, white hairs. Flowers distributed along ±100, rarely up to 150 mm long parts of the branch ends. Bract filiform, 1.5-4 x ±0.2 mm, long-ciliate. Pedicel lacking. Bracteoles usually lacking, seldom present and less than 1.8 mm long, filiform. Calyx tube densely long-and white-sericeous, woolly; lobes linear, (2.5-)3-5.5 mm long, straight, weak, acute, sparsely long-pubescent. Petals pale yellow or the keel often orange or ferruginous. Standard blade ovate, 5.5-7.5 x 3.5-5.5 mm, obtuse or acute (sometimes with a 'tip'), sericeous or tomentose on the back, especially long-hairy on apical parts of the midrib. Wing blades linear, 4-6 x 1.3-2 mm pubescent on the lowermost parts; with 1-2 longitudinal rows of transverse folds on the basal parts. Keel blades 3.5-4.7 x 1.2-2.3 mm, long-pubescent on lower apical parts (± a quarter or a fifth of the blade); upper margin only slightly curved. Wing and keel claws attached to the staminal sheath for a variable distance; wing blades basally attached to pouches of the keel. Pistil sericeous on the ovary and style base. Ripe pods not seen.
