A decumbent or ascending, rather sparingly branched shrublet with main branches up to more than 1 m long, young branches densely short-tomentose or short-villous. LeafÂlets linear, 2—6(-7) mm long, subterete, straight or slightly incurved, glabrous, light green, mucronulate (or acute). Inflorescences consisting of 2 or 3(4) subsessile flowers radiating from the tips of leafy, non-peduncuÂlate branches. Bract linear-subulate, 3,5-5 X 0,5-0,7 mm, acuminate-mucronulate, glaÂbrous abaxially, hairy adaxially on basal half. Pedicel extremely short. Bracteoles 3,5-6 X 0,5-1 mm. Calyx tube 2,5-3 mm long, exterÂnally glabrous, with 5 prominent longitudinal ridges continuing into the midveins of the lobes; these broadly subulate, (4,5-)5-7 mm long, 1,2-2,5 mm broad at the base, acuminate, green, glabrous. Petals largely glabrous, light to bright yellow (rarely with red or brown shades). Standard blade broadly ovate or ellipÂtic, 7,5-9 X 7,2-8,5 mm, glabrous (except for a basal hair tuft), the sides firmly incurved, the apex acute-acuminate, slightly incurved, not thickened. Wing blades oblong or narrowly elliptic, 7-7,8 x 2,8-3,9 mm, with c. 3 rows of few minute folds at the base (fewer than in A. juniperina—no. 243). Keel lunate, 5,8-6,6 x 3-3,6 mm, apically somewhat upcurved and subacute, with concave upper margin and prominent basal pouch. Pistil hairy on upper side of ovary only; ovules 2. Pod broadly triangular-lanceolate, 9-10,5 x 4-4,5 mm, compressed, smooth, greyish green to greyish brown. Chromosome number. 2n=16. Figure 127:10-18.
