Characteristics

A small, erect, rhizomatous suffrutex up to 60 cm tall; resprouting after fires. Stems 1-3, produced at intervals along an underground rhizome, branching in lower axils, erect, basal leaves smallest. Leaves unifoliolate, 25-40 x 15-25 mm, broadly elliptic to broadly obovate, glabrous, scarcely mucronate, mucro arching, base acute, densely nigro-punctate when dried, glands denser on upper surface, margin smooth, younger leaves glabrous, veins prominent below and above; rachis absent; petiole 5-8 mm long; petiolule 1 mm long. Stipules 4-5 x 1-2.5 mm, shorter than petioles, somewhat clavate in lower axils to subulate to linear in upper axils, patent to recurved, glabrous, glandular. Inflorescence axillary in basal axils, lax, 35-55 mm long, comprised of 4-7 triplets of flowers borne on 2 mm long pedicels; each triplet subtended by a broadly ovate, sparsely hairy, persistent, papery bract; peduncle 70-110 mm long, 4-5 times length of subtending leaf. Flowers 10 mm long, colour unknown, each subtended by a small persistent linear bract. Calyx teeth 3 times longer than the 3-3.3 mm long tube, equal, acute; carinal tooth slightly broader than other four teeth, 10 x 3 mm; lateral and vexillary teeth lanceolate, narrowed towards tube; vexillary lobes fused higher up than rest; glabrous all over except for blackish hairs along the margin, venation reticulate; glands common, constant in size, equally distributed on teeth and tube; accrescent. Standard 11 x 3 mm, claw 2 mm long, broadly elliptic, auriculate; claw narrowed. Wing petals 1.1 x 2.5 mm, upcurving, overlapping, auriculate; claw 3 mm long, longer than keel petals; sculpturing upper right central, transcostal, comprised of up to 35 irregular lamellae, rows indistinct. Keel petals 8 x 4-4.5 mm; blade 4 mm wide at widest point; claw 4.5 mm long. Androecium 8 mm long; vexillary stamen free; anthers equal. Pistil 7-8 mm long; ovary 2.5 mm long, covered in black prostrate hairs, densely glandular, height of curvature 2-3 mm long, thickened before flexure; style forward sloping; stigma small. Fruit densely glandular, 8 x 6.5 mm. Seed 5 x 4 mm, dark brown; hilum protruding, central.
