Characteristics

Shrubs to 1.2 m tall, erect, virgate, arising from a single stem at base. Branches erect, slender; bark splitting becoming light brown, smooth with small rather distant leaf scars. Branchlets erect, slender, minutely puberulous, hidden by the leaves. Leaves to 35 mm long on vigorous young stems, more usually 15-18 mm long including petiole about 1 mm long, 1-1.2 mm broad, linear, acute, mucronate, glabrous, pale green, straight, erect, loosely imbricate, alternate margins minutely ciliolate becoming smooth; adaxially concave; abaxially convex, gland dots scattered ±in two rows to either side of the midrib. Inflorescence solitary, terminal or axillary in the uppermost leaves, 12-13 mm diam., pink. Bracts five, increasing evenly in size from 1.4 mm long, 0.4 mm broad at the base to 3.6 mm long, 1 mm broad below the bracteoles, oblong to lanceolate, acute with a small sharp mucro; margins ciliolate, narrowly translucent; adaxially very sparsely pubescent; abaxially glabrous, gland-dotted to either side of the midrib. Bracteoles two, 3.4 mm long, 1.2 mm broad, lanceolate, acute, apiculate, ciliolate with broad translucent margins, glabrous, gland-dotted and reddened along the midrib; adaxially pubescent. Calyx lobes five, 3 mm long, 1.5 mm broad, broadly lanceolate, acute, apiculate; margins broadly translucent, ciliolate; adaxially pubescent; abaxial surface glabrous, gland-dotted and reddened along the midrib. Petals five, 7.6-8.5 mm long overall; limb 5.3 mm long, 3.6-4.2 mm broad, obovate, apiculate, glabrous, gland-dotted on the underside, pink, spreading; claw 2.5 mm long, narrowing to 0.4 mm wide at the base, glabrous, connate with the staminode except above where, two small pointed processes surround the apical gland of the staminode on either side. Staminodes five, 2.5 mm long, 0.3 mm broad, connate with the petal except above; apical gland conical, exudes nectar. Filaments five, becoming 1.7 mm long, acicular, glabrous, erect. Anthers five 1.1 mm long, 0.6 mm broad, yellow; apical gland small, globose, exudes nectar. Pollen 47 µ long, 27 µ broad, ellipsoid. Disc obvallate, margin free, exceeds the ovary, equalling the stigma, fairly narrow, level above, green, exudes nectar. Stigma 0.4 mm diam., capitate, depressed globose. Style becoming 1.3 mm long, slender, glabrous, erect, persisting. Ovary 5-carpellate, 0.8 mm long, 0.8 mm diam., glabrous, apices globose. Fruit 5-carpellate, 5.5 mm long (6.7 mm long to the tips of the horns), 4.7 mm diam., 6.7 mm broad across the horns, green, glabrous, many gland-dotted; horns 2 mm long, spreading and curved up slightly; apices emarginate clasping an immersed gland. Seed 4.6 mm long, 1.8 mm broad, black, shining; aril black capped.
