An erect or ascending, rather much branched shrublet 0.3-0.8 m tall. The youngest branches, including the 'peduncles', tomentose (-woolly); lateral floriferous branchlets with one (or two) prolonged, peduncle-like internodes, 5-35 mm long, but distally with at least two short leaves situated close to the flower (s). Leaflets linear or subfiliform, 3-10(-12) mm long, slender, weak (flexible), acute, with dense, rather short, tomentose, grey or white pubescence. Inflorescences consisting of (1-)2-4 closely set flowers on the apices of the peduncle-like branchlets, subtended by two or more vegetative leaves. Bract linear or filiform, 2-4 x 0.1-0.2 mm, flexible, pointed, pubescent, often pigmented. Pedicel 0.5-2 mm long, densely pubescent. Bracteoles 1.5-4.5 x less than 0.2 mm. Calyx (woolly-)tomentose; lobes linear, (2-)3-6 mm long, soft, acute, sericeous or tomentose. Petals pale or light yellow on most parts but part of keel and standard often ± purplish. Standard blade 5.5-8(-9) x (5.5-)6-8(-10) mm, acute to retuse with a 'tip' (shorter than 0.4 mm), back tomentose on most parts (glabrous on base). Wing blades 3.5-5(-5.5) x (1.3-)1.5-2(-2.5) mm. Keel blades 5-6.2(-7) x 2.5-3.5 mm, with slightly convex to slightly concave upper margin. Pistil long-hairy on most parts of ovary. Pod ovate, 4-5 x 2.5-3.5 mm, tomentose or sericeous on most parts.
