Stipules 2-3 mm long, subulate, apex attenuate, striate, glabrous, clasping. Inflorescences axillary in the upper axils of short < 30 mm long seasonal shoots, congested, each comprised of a triplet of shortly pedicellate flowers and subtended by an oblanceolate to flabellate, multi-veined, 3-3.5 mm long bract, peduncle < 2 mm long, each flower subtended by 1 or 2 narrowly lanceolate bracts. Flowers 9-10 mm long, white, pedicels 2 mm long. Calyx shorter than the corolla; lobes unequal, veins prominent, carinal lobe longest, 8 x 1.8-2 mm, broader than the equal lateral and vexillary lobes, the latter fused for 1 mm above the 2-2.5 mm long tube; teeth lanceolate, or broadly lanceolate, acuminate, hirsute, margins ciliate; vexillary teeth not fused above the tube; glands scattered, small, mostly on the teeth.
