Description: Shrub or small tree up to 4 m tall. Indumentum of branchlets, petiole, stipules, pedicel, abaxial surfaces of bract and bracteoles and external surface of calyx dense, golden-brown, hairs curled, sometimes a small proportion of hairs longer and divergent.
Leaves lorate to very narrow-elliptic, 3–8 cm long, 5–16 mm wide (juvenile leaves to 11 cm long with petiole to 5.5 mm long), flat, midrib slightly recessed; base obtuse to acute; margins flat to slightly recurved; apex obtuse to acute, mucronate; upper surface green, glossy, smooth, glabrous or with scattered hairs along midrib, veins indistinct; lower surface with curled, golden hairs mostly confined to veins, midrib hairs dense, orange-tan, venation pattern emphasised by haircolour. Stipules ovate, c.1 mm long.
Inflorescences pedunculate, peduncle 1.5–4.5 mm long, commonly 3-flowered. Flowers with bracts inserted 1–2 mm distal to base of pedicel, oblong to ovate 1.0–2 mm long; bracteoles inserted at or rarely proximal to base of calyx, oblong to narrow-ovate 1.2–2.2 mm long; calyx 4.5–5 mm long; tube 2.5–2.8 mm long; upper lip 3–4 mm wide across base, slightly narrower apically, apex of lobes truncate to rounded, intervening sinus 0.5–1 mm deep; lower lip 5–6 mm wide across base, lower lobes with an acuminate apex, 1.5–1.8 mm long. Standard 8–9 mm long, 11–12 mm wide, claw c. 2 mm long, limb mauve, flare green-yellow, 1–2 mm wide, bordered by a zone of deep mauve; wing 7–8 mm long, 3.5–4 mm wide, claw c. 2 mm long; keel 5–5.5 mm long, 2–2.7 mm wide, claw c. 2 mm long; style hairy for the first 1–2 mm.
Pod obliquely orbicular to broad-elliptic in profile, 10–17 mm long, 9–12 mm deep, sessile, external surface hardly obscured by brown, crumpled hairs, internal surface with scattered hairs. Seeds ellipsoid, 6–7 mm long, 3–3.5 mm wide, black to brown, aril narrowoblong, c. 6 mm long, 1.8 mm wide, extending c. 90% of length of seed.
