Leaves 2-3.6 mm long, 1.5-2.0 mm broad, elliptic, obtuse, sessile, glabrous, subglaucous, spreading-erect, alternate; abaxial surface gland-dotted all over, Midrib prominent; margins thick, gland-dotted. Inflorescence terminal with flowers creamy-white, sessile, up to 8-aggregate. Bract one to each flower, 0.8-1.4 mm diam., the outermost larger, orbicular, obtuse, glabrous, gland-dotted. Bracteoles two, 1 mm long, 0.6 mm broad, asymmetrically orbicular, ciliolate, glabrous, gland-dotted. Calyx lobes five, 1.5 mm long, 0.8 mm broad, oblong, very obtuse, apex thickened, glabrous, gland-dotted; margins below translucent and ciliolate. Petals five, 3 mm long over all, creamy-white; limb 1.2 mm broad orbicular; claw 1.1 mm broad, narrowing to the base, strongly crisped bearded and ciliate. Staminodes completely absent. Filaments five, becoming 6 mm long acicular, glabrous. Anthers five, before anthesis 1.2 mm long, 0.6 mm broad cream-coloured, pinkish above; apical gland minute, globose. Pollen 45 µ long, 23 µ broad, oblong. Disc closes right over the ovary, dark green, excudes nectar. Stigma simple, a red dot at the apex of the style. Style becoming 6.6 m long, terete, glabrous. Ovary tri-carpellate, 0.5 mm long, 0.6 mm diam., glabrous. Fruit normally 3-carpellate (in a random sample of 87 fruits, 6 had carpels. Of the remaining 3-carpellate fruits, 13 developed all three carpels, 3 developed only two and 33 developed only one carpel) 2.5 mm long overall glabrous, gland-dotted; horns about 4 mm long, spreading at 45°, apex emarginate. Seed 6, 3 mm long overall including the white aril, 2.1 mm broad, black matt, mottled.
