Stipules 6-9 x 2-2.5 mm, subulate, attenuate, 5-6-nerved, glabrous except for scabrellous margins. Inflorescences borne solitarily towards shoot tips, rounded, compact, 25-30 mm long, comprised of 4-6 triplets of pedicellate flowers, each triplet subtended by a 10-12 x 7-9 mm, lanceolate, acuminate bract; peduncle 25-30 mm long, about equal to length of leaflets. Flowers dark pink fading white with age, nectar guide white, 15-17 mm long; bracts persistent. Calyx teeth 2-2.5 times longer than the 4 mm long tube, teeth equal; four upper teeth lanceolate, carinal tooth naviculate; venation thick, reticulate; carinal lobe 15-16 x 5.5-6 mm, lateral lobes 3-4 mm wide, equal to vexillary lobes; all covered in erect very short white hairs and long black hairs, glabrous on inner face. Standard 16-17 x 13-14 mm, claw 2 mm long, recurved; broadly ovate, reddish purple, appendages absent, auricles prominent, glabrous. Wing petals 16-17 x 7 mm, longer than keel blades, spathulate, upcurving, auriculate, claw 5 mm long; sculpturing upper basal and central comprised of 50-60 broad transcostal lamellae. Keel blades 12 x 4 mm, apex rounded, claw 5 mm. Androecium 11 mm long, fenestrate; vexillary stamen free, anthers equal, 0.7-0.8 mm long. Pistil 12-13 mm long; ovary 3 mm long, pilose; height of curvature of style 4 mm, thickened at curvature, hairy until curvature, stigma capitate, penicillate.
