Characteristics

Undershrubs 300 mm tall, semi-decumbent, arising from a single stem almost below ground level. Branches tending to sprawl, glabrescent, greyish-brown, with small leaf scars. Branchlets numerous, fairly erect, sparsely pubescent, well clothed with leaves, many sprout from the older wood. Leaves 6-8 mm long, 1,2 mm broad, linear-lanceolate or subulate, incurved-erect, sessile, alternate, apex pubescent and acute without any callus, ciliate almost without any hyaline margins; adaxial surface glabrous, concave; abaxial surface pubescent with scattered long hairs, round backed with many indistinct gland dots scattered mainly towards the midrib. Inflorescence terminal, 4-6 aggregate; flowers 5 mm diam., white. Bract 2.5-4.5 mm long, 0.8-1 mm broad, the inner smaller, similar to the leaf but with broad translucent margins towards the base. Bracteoles two, 1.6-2 mm long, 0.6 mm broad, oblong, apex sub-acute and tufted with bristly hairs, ciliate above, margins broad and translucent. Calyx lobes five, 3 mm long, 1 mm broad, narrowly lanceolate, apex a blunt hairy point, ciliate, margins translucent below. Petals five, 5 mm long, white; limb 1.4 mm broad, ovate, sub-acute, spreading; claw 1.2 mm broad, crisped-bearded above in the centre, eciliate. Staminodes five, 0.3 mm long, slender with a minute apical gland, arising at the outside base of the disc at the base of the petal, in many cases almost invisible. Filaments five, glabrous, becoming 6-7 mm long after anthesis. Anthers five, 1.2 mm long, 0.7 mm broad, yellow, oblong with a small apical gland. Pollen 52 µ long, 22 µ broad, oblong. Disc green, envelops the ovary, touching the base of the style, exudes nectar. Stigma simple, terminal. Style becoming 6 mm long, glabrous, pink at the tip. Ovary 3-carpellate, 0.6 mm diam., globose, glabrous. Fruit (from Williams 2261) 3-carpellate with normally only one carpel developing, 12 mm long, 3 mm broad, pubescent, reddish gland-dotted; horns 5 mm long, erect, slender. Seed 4.2 mm long, 1.8 mm broad, truncate with the aril extending 1.3 mm, black, matt.
