Characteristics

Shrubs up to 0.9 m tall or grazed down to 0.1 m, dense, with many stems arising from ground level. Branches glabrous, on vigorous young plants straight, erect and quite long but more usually short, spreading at 45° angles, interlocking. Branchlets slender, short, glabrous, spreading at 45°. Leaves on vigorous young plants 5 mm long, 4.2 mm broad, on older plants about 2.1 mm long, about 1.9 mm broad, ovate-cordate, sub-acute, sessile, alternate, glabrous, glaucous, flat, fleshy, spreading at 90°, margins eciliate, narrowly cartilagenous, somewhat thick; gland dots few on margins and midrib. Inflorescence terminal with flowers sessile, creamy-white, aggregated into groups of up to 7. Bract varies, outermost leaf-like, inner 1 mm long, 0.6-1.0 mm broad, sub-orbicular, glabrous, very sparsely ciliate, apex with a blunt point. Bracteoles two, 0.8 mm long, 0.6 mm broad, asymmetrically oblong; apex thick with a small obtuse point; midrib thickened; hyaline margins sparsely ciliolate. Calyx lobes five, 2 mm long, 0.9 mm broad, oblong, obtuse with a small blunt point; margins broadly translucent, minutely ciliolate above; adaxial surface minutely pubescent towards the apex; abaxial surface round, keeled, glabrous, obscurely gland-dotted. Petals five, 3.7 mm long overall; limb 1.7 mm broad, orbicular, obtuse. Claw 1 mm broad, very strongly crisped bearded above. Staminodes absent. Filaments five, becoming 6.3 mm long, straight, glabrous. Anthers five, before anthesis 1.  long, 0.7 mm broad, wine-coloured; apical gland minute. Pollen 45 µ long, 20 µ diam., oblong. Disc green, curls over the ovary, exudes nectar. Stigma simple. Style becoming 7.5 mm long, straight, terete, glabrous, narrower below. Ovary 3-carpellate, 0.6 mm diam., glabrous. Fruit 3-carpellate, usually with one developing to maturity, 9.5 mm long overall, glabrous, gland-dotted, sometimes reddened; horn 3 mm long, fairly erect, apex bifid. Seed 5.5 mm long, including the aril 1 mm long, 1.8 mm broad, black, matt, mottled; aril white.
