A small, decumbent pyrophyte. Stems many, up to 30 cm long, appressed pubescent, slender, striate. Leaves digitately trifoliolate, petiolate, erect. Leaflets unequal; terminal leaflet 10-13 x 3-4(-5) mm, obovate; laterals smaller, asymmetrical, upper margin straight, lower convex; veins distinct below, apex acute, base cuneate, glabrescent; glands impressed, more evident on upper surface; petioles 2-4 mm long, petiolules 0.75-1 mm long. Stipules 4-5 mm long, narrowly subulate becoming broadly subulate in upper axils, ciliate. Inflorescences pedunculate, axillary, common in upper =3 of seasonal shoots, each comprised of a triplet of pedicellate flowers, each triplet subtended by a yellowish 3 mm long, oblong-obovate, irregularly toothed, truncate bract; peduncle 4 mm long. Flowers 8-9 mm long, pedicels 3 mm long, white suffused with mauve; each flower subtended by a 3 mm long, cucullate, narrowly lanceolate bract. Calyx longer than the corolla; 8-10 mm long; carinal lobe longest, 6.5-7 x 2.5-3 mm, acuminate, three times longer than the 3 mm long tube; vexillary teeth shortest, not fused above the tube, lateral teeth intermediate, ribs weak, finely glandular mostly on the tube, margin of the teeth velutinous. Standard 9-10 mm, claw 2 mm long, elliptic, apex obtuse, auriculate. Wing petals 8-9 x 2 mm, claw 2-3 mm wide; auriculate; sculpturing present, upper basal and upper left central, comprised of up to 10 transcostal lamellae. Keel petals 6 x 1.5 mm, claw 3 mm long, base curling upwards. Androecium 6-6.5 mm long, vexillary stamen free. Pistil 5-5.5 mm long; ovary 1.25-1.5 mm long, sparsely stalked-glandular, gynophore 0.4 mm long; style glabrous, entasis developed maximally at point of flexure, height of curvature 1.5 mm, stigma penicillate.

It is easily separated from all other species of Otholobium by a combination of its decumbent habit, long hair-like mucro on the leaflets, and narrowly subulate stipules.
