Shrubs 0.3-0.4 m tall, diffuse, single-stemmed at base. Branches erect, slender, somewhat lax, few in number, glabrescent. Branchlets erect, slender, reddened, puberulous with a minute erect pubescence, well-clothed with leaves. Leaves 10-12 mm long, 1.5-1.7 mm broad, linear-lanceolate, acute, incurved-mucronate, dark green, indistinctly gland-dotted, petiolate, alternate; midrib fairly prominent, at first somewhat pubescent becoming glabrous; margins ciliate becoming serrulate. Inflorescence terminal, with up to 60 florets at the ends of very short branchlets aggregated into heads. Bract one to each floret, 4-4.5 mm long, 0.8 mm broad, linear-lanceolate, acute, mucronate, glabrous except for a few hairs on the prominent midrib, ciliate, obscurely gland-dotted. Bracteoles two, 2 mm long, 0.6 mm broad at base, lanceolate-acute, minutely mucronate, ciliolate, glabrous; margins translucent. Calyx lobes five, 2.6-3 mm long, 0.9-1.4 mm broad, oblong, acute, incurved-mucronate, adaxially pubescent otherwise glabrous, brown or purplish above; margins translucent, ciliolate. Petals five, 4 mm long overall; limb 2-2.3 mm long, 1.4-1.7 mm broad, orbicular, white, subacute; claw 1.8-2 mm long, 0.9-1.4 mm broad, transversely bearded and ciliate above, narrowed and glabrous below. Staminodes five, 0.15 mm diam., vestigial, upon the elevated lobes of the disc. Filaments five, becoming 1 mm long, glabrous. Anthers five. 0.9 mm long, 0.6 mm broad, reddened, apical gland minute. Pollen 38 µ long, 20-25 µ broad, ellipsoid. Disc sinuate-crenulate, spreading, green, fleshy, exceeds the ovary at first. Stigma 0.3-0.5 mm diam., capitellate. Style 0.6 mm long, glabrous, at some stage deflexed. Ovary 5-carpellate, 0.7 mm diam., apices reddened. Fruit 5-carpellate, 4-5 mm long, 3.5-4.5 mm diam., glabrous or with a few spiky hairs along the upper edges on the inside; horns 0.7-1.0 mm long, with a sunken gland near the apex. Seed 2.7-2.9 mm long, 1.5 mm broad, black, shining; aril black.
