Shrubs up to 1.2 m tall, well-branched, single-stemmed at base. Branches short, fairly erect, glabrescent. Branchlets short, erect, puberulous, densely leafy. Leaves up to 11 mm long, those of younger plants larger and more pubescent, 3.8-4.8 mm broad, elliptic, obtuse, petiolate, alternate; margins narrowly cartilaginous, scabrid, crisped ciliate when young; adaxial surface grooved down the middle, minutely puberulous; abaxial surface scabrid, often minutely puberulous, gland-dotted with the midrib prominent, scabrid, pubescent or shaggy pubescent. Inflorescence terminal, solitary, 15 mm diam., pink, closed at the throat. Involucral leaves much reduced, becoming bract-like. Bracteoles two, 2.7 mm long, 1.5 mm broad, elliptic, obtuse, concave, translucent, glabrous, ciliolate; apex soon withering. Calyx lobes five, 5-6 mm long, 2.5-3 mm broad, oblong, obtuse, pseudo-apiculate due to the inrolled margins and with a tuft of hairs, 3-veined, glabrous, ciliate, translucent, shining. Petals five, vary in size, 13 mm long; limb 7 mm long, 5.5 mm broad, orbicular, apiculate, thinly puberulous above, ciliolate; claw 6 mm long, 1.5 mm broad above, 0.8 mm broad below, ciliate and pubescent above, arched inwards almost closing the throat. Staminodes five, 0.2-0.4 mm long, fusiform, glabrous. Filaments five, becoming 2.4 mm long, acicular, glabrous. Anthers five, before anthesis 1.7-1.8 mm long overall, 1 mm broad, yellow; apical gland 0.2 mm long, sub-acute. Pollen 55 µ long, 24 µ diam., oblong. Disc obvallate, exceeds the ovary, green, quite fleshy, exudes nectar. Stigma 1 mm diam., globose, capitate. Style becoming 1.5-2.3 mm long, glabrous, erect. Ovary 5-carpellate, 1 mm long, 1.2 mm diam.; apices globose, puberulous, adaxially emarginate. Fruit 5-carpellate, 5 mm long, 4.5 mm diam., enclosed within the persistent calyx lobes; carpels glabrous, smooth, gland-dotted towards the margins; horns very short, 0.3 mm long, emarginate, echinulate. Seed 3.5-3.8 mm long, 1.5-1.6 mm broad, black, shining; aril black on one side.
