Erect, multi-stemmed shrub, up to 0.5 m tall, sprouting from woody rootstock after fire. Branches sericeous, glabrescent. Leaves alternate, simple, 10-16 x 1-2 mm, lamina linear, with strongly revolute margins, pubescent on adaxial surface, glabrescent, densely sericeous on abaxial surface, apex acute; petiole ± 1 mm long, sericeous; stipules inconspicuous. Inflorescences axillary, with paired (geminate) flowers, grouped into flowering units of up to 20 flowers; peduncle short, < 1 mm long, sericeous. Bracts linear, ± 1 mm long, fused at base with pedicel for 0.5 mm. Pedicel 3 mm long, sericeous. Bracteoles minute, situated at thickening on pedicel. Corolla yellow, fading brown with age, longer than calyx, glabrous. Calyx narrowed to base, not intrusive; lobes triangular, acuminate; upper two lobes fused higher up than lower three lobes; lower lobe as long as upper four lobes, pubescent. Standard petal suborbicular, apex emarginate, base cuneate. Wing petals oblong, longer than keel; auricle weakly developed, pocket developed as a thickened lobe towards inside, inconspicuous on outer surface. Keel petals oblong, pocket weakly developed, apex obtuse. Stamens diadelphous, vexillary filament free; anthers ± uniform in shape and size, alternately dorsifixed and sub-basifixed. Ovary with 2 or 3 ovules, densely sericeous; pistil sessile; style slender, curved upwards, glabrous. Pods coriaceous, obliquely oblong, laterally compressed, constricted between seeds, 2-or 3-seeded, densely pubescent, glabrescent. Seeds oblong-reniform, brown to deep dark brown; hilum elliptic, surrounded by a fleshy collar-like aril.
