An erect or ascending, copiously branched shrub up to 0.75 m tall, with grey branches. Young branches very slender, light yellowish, with short, tomentose pubescence. Axillary leafy short-shoots rapidly developed in the axils of the long-shoot leaves; leaflets therefore in clusters, 3-6(-9) together. Leaflets succulent, sausage-shaped or ovoid, 1-2 mm long, ±0.6 mm thick, terete, obtuse (to subacute), light green, glabrous. Inflorescences unifloral on tips of branchlets; each flower ±0.5 mm beyond the nearest leaf. Bract broadly oblanceolate-oblong, ±2.5 x 1.2 mm, obtuse-subacute, glabrous. Pedicel ±0.5 mm long, puberulous. Bracteoles fusiform-oblong, 2.5-3.5 x ±1 mm. Calyx tube campanulate, 2.5-3 mm long, thinly short-tomentose; lobes triangular to very broadly subulate, 1.5-2 mm long, green, thick, carnose, glabrous, subacute. Petals light yellow, glabrous. Standard with blade ovate, 9-10 x 7-8 mm, apically incurved and obtuse-subacute; claw ±1.5 mm long. Wing blades very narrowly elliptic, ±6.5 x 2.2 mm, rounded, without prominent upper-basal ear, with ±4 rows of minute folds; claws ±1.6 mm long. Keel blades rounded-arcuate, ±7.5 mm long and ±3 mm across (broadest part), with rounded apex and concave upper margin; claws ±1.5 mm long. Pistil puberulous on ovary and style base; ovules 2. Fruit narrowly triangular-ovate, ±7 x 3.3 mm, finely grey-sericeous.
