Characteristics

A small, decumbent, sparsely leaved suffrutex up to 20 cm high; resprouting after fires. Lignotuber present. Stems arising from a short thickened trunk, up to seven, 90-150 mm long, occasionally branched in one of the lower axils, basal leaves smallest, densely pustulate. Leaves unifoliolate, 25-36 x 6-9(-10) mm, elliptic, glabrous, cuspidate, mucro straight, apex acute, base cuneate, densely nigro-punctate when dried, margin glandular, younger leaves glabrous, midrib prominent below, secondary veins on both surfaces raised but less prominent; rachis absent; petiole 2 mm long; petiolule 1 mm long. Stipules 3-5 x 0.5-2 mm, longer than petioles; glabrous, subulate, acuminate, ribbed, glandular. Inflorescences axillary, 1-2 in upper axils, terminating short seasonal shoots, oblong, 25-35 mm long, comprised of 5-9 triplets of flowers with 2-4 mm long pedicels, each set subtended by a flabellate to broadly ovate-oblong, gland-dotted hairy bract, bract caducous; peduncle 25-35 mm long, about twice the length of the subtending leaf, densely covered in 0.2 mm high warts. Flowers white, 8-10 mm long, each subtended by a narrowly lanceolate to linear, 3 mm long, caducous bract. Calyx teeth longer than the 2-3 mm long tube, unequal, acute; carinal tooth broadest, 10-11 x 2-2.5 mm, dark green, rest of calyx pale yellowish green; vexillary lobes falcate, same length as the lateral lobes, fused for =3 their length above the tube, outer face densely covered in 1.5-2 mm long white patent hairs and many small glands, glabrous on inner face. Standard 13 x 8-9 mm, obovate, but oblong when reflexed; white to pale blue, auriculate, claw 2 mm long, narrowed. Wing petals 10-12 x 3-4 mm, claw 3 mm long, cultrate, upcurving relative to keel, auriculate, longer than and very lightly fused to keel petals; sculpturing upper right central, sometimes upper distal, bottom row intracostal, upper two rows transcostal, each row comprised of up to 25 transverse lamellae. Keel petals 9 x 2.5-3 mm, claw 4 mm long, purple-tipped. Androecium 8 mm long, vexillary stamen free; fenestrate; anthers equal, 0.3 mm long. Pistil 8 mm long; ovary 1.8-2 mm long, tomentose, stipe 1 mm long and glabrous; height of curvature of style 2.5-2.8 mm, thickened before flexure; style forward sloping, sparsely hairy up to entasis; stigma slightly penicillate. Seeds and fruits unknown.
