A decumbent or procumbent (but not prostrate) shrublet with branches up to 0.6 m long or more, sparingly to fairly much branched, with ascending branchlets rarely reaching more than 0.15 m above the ground. Young branches and branchlets tomentose or short-villous, usually reddish. Leaflets linear, (0.5-)1-2.5(-3) mm long and ±0.5 mm thick, terete, obtuse or subacute, glabrous or sparsely tomentose, ± straight, bright green. Inflorescences usually unifloral, on tips of (often very) short branchlets or on short-shoots. Bract simple, linear, 2-3 mm long, 0.3-0.6 mm broad, pale at the base, otherwise green, succulent, obtuse. Bracteoles similar to the bract, 2.5-3.5 mm long. Calyx tube pale or reddish, longitudinally ridged, subglabrous or sparsely short-tomentose; lobes triangular, 1-3.5(-4) mm long, succulent, green, obtuse (subacute), glabrous or sparsely puberulous. Petals bright to pale yellow. Standard blade circular or broadly obovate, 6.3-8 x 7-9 mm, apically rounded but often with a 'tip', sericeous(-tomentose) on the back. Wing blades narrowly elliptic or obovate, 6 x 2-3.2 mm. Keel blades lunate, 6.5 x 3-4 mm, obtuse, glabrous, with ± convex upper margin. Wing and keel claws usually not adnate to the staminal sheath. Pistil short-stipitate; ovary tomentose. Pods not seen.
