Shrubs up to 1.5 m after more than 50 years, normally much less, branching from near the base. Bark fairly rough, greyish-brown, without leaf scars. Branches slender, erect, glabrous, ashy in colour, divaricate, becoming leafless. Branchlets slender, erect, short, glabrous, reddish, shining, either not much hidden by the leaves or densely foliate. Leaves vary considerably in size, 2-9 mm long, 1.1-1.7 mm broad, linear-elliptic or elliptic, obtuse, thickened towards the apex, hyaline margins narrow, thick and smooth or scabrid, glabrous, sessile, adaxial surface flat becoming concave when dried, abaxial surface convex and gland dotted, adpressed or spreading-erect, distant or crowded, scattered. Inflorescence terminal, usually in pairs. Bract one to each flower, 2.5 mm long, 1 mm broad, oblong, obtuse, thickened at the apex, glabrous, gland dotted, ciliolate. Bracteoles two, 2.4 mm long, 1 mm broad, lanceolate sub-acute, glabrous, gland dotted, ciliolate. Calyx lobes five, 3 mm long, 1.8 mm broad, deltoid, acute, glabrous, gland dotted, ciliolate, adaxial surface very short-pubescent below. Petals five, 4.8 mm long, 1.4 mm broad, oblanceolate, obtuse. Limb white, glabrous, recurved. Claw narrowing to the base, transversely bearded and somewhat ciliate above. Staminodes five, 0.15 mm diam., each a minute vestigal translucent spherical gland. Filaments five, becoming 1.3 mm long, acicular, glabrous, curving inwards. Anthers five, before anthesis 0.9 mm long, 0.7 mm broad below, wine red, apical gland 0.2 mm diam. Pollen oblong, 42 µ long, 22 µ diam. Disc 5-sinuate, exceeds the ovary, exudes nectar. Stigma 0.25 mm diam., globose, green, capitellate. Style becoming 1 mm long, terete, glabrous. Ovary 5-chambered, 0.8 mm diam., glabrous, apices hemispherical. Fruit (from Esterhuysen 27907) 5-carpellate, 6.5 mm long, glabrous, gland dotted. Horn 1 mm long, with a spherical gland clasped at the apex. Seed (from Esterhuysen 27907) 4.3 mm long, 2 mm broad, black, shining.
