Stipules lanceolate, ca. 5-6 mm long, reflexed, apex obtuse, base with lateral auricles, more or less cordate, margins ciliate, more or less truncate-elongated below point of insertion in seedlings only. Inflorescences axillary, pedicel somewhat compressed and winged, sparingly patent, ca. 100 mm long, bearing two small flowers at the apex, with a vertical row of glands between the pedicels. Flowers cream-flushed with green and a yellow spot at base of erect standard. Calyx campanulate, lobes acuminate with broad triangular bases, about as long as tube, ca. 2 mm, upper pair connate for 1/3 to 1/2 their length, patently pubescent.

Ovary pubescent, ca. 9 mm long; style broadened and flattened as it curves upward, bearded on anterior face, apically twisted at maturity, elongated beyond stigma like an erect fingertip, ca. 0.2-0.3(-0.4) mm long; stigma anteriorly lateral, globose before pellicle is broken, with short hairs at base. Legumes erect, slightly compressed, ca. 60 mm long, obtusely beaked, with longish white hairs, ca. 12-14-seeded.
