A decumbent to prostrate shrublet, sometimes forming small, loose, mats on the ground. Young branches silky sericeous. Leaves trifoliolate; those on branch ends without, those on more basal parts with axillary short-shoots. Leaflets of long-shoot leaves flat, linear to oblanceolate,(3-)5-8 x 0.5-1.5 mm, acute, weak, silky sericeous but greenish(not as silvery as, e.g. A. villosa). Inflorescences capitate, with 3-10 flowers, terminally on branches or branchlets. Bract flat, oblanceolate, 4.5-5 x 1-1.5 mm, flexible, sericeous on both sides. Pedicel almost non-existent. Bracteoles similar to the bract, ±5.5 x 1-1.3 mm. Calyx campanulate, sericeous; lobes triangular, 1.5-2.5 mm long, acute, sericeous. Petals small in relation to calyx, pale scarlet ('mauve'), with claws almost as long as blades. Standard blade obovate, only 2.5-4 x 3-3.5 mm, rounded apically, sparsely tomentose on most of the back (subglabrous towards the margins). Wing blades, 3.5-4.5 x 0.9-1.2 mm, linear-oblong, tapering rather than lobulate above at the base, with ±3 rows each with a few minor folds on the basal upper part, glabrous or with a few hairs on outer side. Keel blade lunate, 3-4 x 1.2-1.5 mm, with slightly concave upper margin, sericeous on most of the outside. Pistil with elongate ovary; this and the style base sericeous on most parts (glabrous below); ovules 2. Pod partly hidden in the calyx, narrowly ovate, ±4.5 x 1.5 mm, pointed, sericeous on most parts.
