Leaflets 10-17 x 0.8-1.0 mm, linear, grooved, slightly flattened on abaxial surface, semi-erect to erect, mostly incurved, glabrous, green, arranged in dense clusters of 3-5 tightly packed on raised black ciliate bases each base with 3-6 leaflets. Inflorescences (1)2(3)-flowered, either axillary or terminating short scabrid lateral shoots or pseudospines; many, scattered along seasonal branches. Flowers 9-10 mm long, bright yellow, shorter than leaves; pedicel 4-5 mm long, scabrid; bracts 4-5 mm long, linear, incurved, inserted one third up the pedicel; bracteoles offset, situated just above bracts, subulate, incurved, densely scabrid on inside calyx 6-7 mm long, campanulate, sparsely appressed scabrid; teeth green, narrowly subulate, 3-4 mm long, equal, clearly demarcated from the yellowish tube, glabrous inside; tube 2.5-3.0 mm long, shorter than teeth.

Wing blades 9 x 2 mm, glabrous, blade linear, notched towards lower apex, glabrous; petal sculpturing obscure, reduced to 1-2 lunate folds in deep pocket near auricle; claw 2 mm, slightly upcurved, ciliate near upper base. Keel petals 8 x 3 mm, blades fused, glabrous but margin near base micropapillate, 5.5 m long, scarcely auriculate, obtuse, with well-developed pocket; claw 2-3 mm long, tapering. Androecium 9 mm long with 5 basifixed and 5 dorsifixed, versatile anthers.
