Leaflets 15-22 mm long, (4)6-8(11) mm wide (the larger eaves being produced later in the season), flat, entire, j-'liptical, sericeous but denser below especially along veins; ase obtuse, apex strongly recurved-mucronate; laterals smaller than the terminal leaflet. Inflorescences 6-15-flowered, axillary, hemispherical on long peduncles comprised of 2-4(5) sets of flowers in triplets, lowest set subtended by a 2-3-toothed flabellate bract; bracts gradually narrowing in remaining sets; filiform bractlets subtending each flower. Flowers 8-11 mm long, mauve becoming purple with age, enclosed within the calyx at anthesis, but standard reflexing partially; pedicel 1.5-2.0 mm long. Peduncle (50)90-120(200) mm long. Calyx 11-13 mm long; lobes unequal, upper four teeth equal, narrowly triangular, curved, 5.5-6.0 mm long, 1.5-2.0 mm wide, keel tooth 9-10 mm long, 3.0-3.5 mm wide; veins prominently reticulate; tube 2.5-3.0 mm long. Standard 8-10 mm long, 5.0-6.5 mm wide, obovate, slightly reticulate, narrowed towards the 3 mm long claw. Wing petals 9.5-0.0 mm long, blade 6-7 mm long, 2.2-2.5 mm wide, longer than the keel, auriculate, sculpturing upper basal and left central, comprised of 15-18 irregular parallel lamellae. Keel blades 8 mm long, 2 mm wide; apex rounded, blotched purple on inner face. Androecium 8 mm long, vexillar stamen 7.5 mm long, loosely attached to the sheath for half its length. Pistil 8 mm long; ovary 1.5 mm long, sparsely glandular, subsessile; style glabrous, height of curvature 2 mm, flexure thickened, stigma papillose. Seed and fruit unknown.
