Tree-like shrub up to 2 m tall, open habit, woody; branches sparsely appressed strigulose when young but glabrous when mature. Stipules free, filiform, strigulose, up to 2 mm long, parallel to axis of branch. Leaves common on younger plants, petiolate, basal pair largest, upper pairs being reduced to scales. Basal leaflets 6-8, elliptic, rarely narrowly obovate, 15-20 x 8-10 mm; base cuneate; apex mucronate, straight; glabrous above, sparsely and evenly scattered with appressed biramous hairs beneath. Petiole 40-60 mm long; petiolules up to 2 mm long. Inflorescences axillary, clustered at ends of branches forming a pseudo compound structure, racemose, lax, up to 50-flowered. Flowers (7.5)8.0-0.5 mm long, each subtended by a short 1-2 mm long, narrowly triangular, rapidly caducous bract; pedicel 4.0-4.3 mm long. Calyx 4.0-4.5 mm long; tube 1.7-3.4 mm long; teeth unequal, 1.1-3.0 mm long; triangular sinus between vexillar pair very broad, hairs few, scattered in the sinuses of the teeth. Standard (6.1)8.4-9.2(0.2) x (5)6.3-7.6 mm, orbicular; claw very short; venation fine, branching from three traces at the base; apex slightly hooded, auricles and appendages absent. Wing petals 9-10 x 2.5-3.0 mm, constricted in the middle; auricle inflated and flattened. Keel petals 9 x 3.0-3.5 mm; apex pubescent. Androecium 9-10 mm long; vexillar stamen free; anthers uniform, 1 mm long, apiculate and tufted, anthers on long filaments basifixed, those on short filaments dorsifixed; scales present. Pistil 6.6-9.0(9.9) mm long, terete, <0.5 mm wide, glabrous, arched, narrowly oblong, 8-14-ovuled; style upcurved, height of curvature 2 mm. Fruit 40-55 x 4 mm, dark brown, dehiscent. Seeds 2.6-2.7 mm long and wide, chocolate-brown, hilum protruding, transversely oblong. The plants flower throughout the year but with a peak from February to March. This species coppices strongly after burns.
