Characteristics

Shrubs 30-100 cm tall, fairly erect, spreading up to 1.2 m wide, not dense, arising from a single stem at ground level. Bark dark brown, smooth with small leaf scars on the lower branches. Branches short, glabrescent, knotty with raised leaf scars. Branchlets short, fairly slender, leafy, clothed with a short dense white pubescence. Leaves 13-15 mm long, 1 mm broad, sub-terete, subulate, eciliate, gland-dotted, scabrid, with a short reddish petiole, crowded, sub-imbricate, fairly erect, somewhat falcate when dry, scattered. Inflorescence a much reduced compound raceme with flowers 1-3nate, 3 mm diam., star shaped, white, opening in succession, more or less surrounded by the uppermost leaves. Pedicel 2 mm long, puberulous, with a pair of bracteoles about the middle. Bract 6.5-7 mm long, 0.7 mm broad, subulate, sparsely puberulous, gland-dotted, minutely ciliolate; the innermost 4 mm long. Bracteoles two, 4 mm long, otherwise similar to the bracts. Calyx lobes five, 4-4.5 mm long, 1.7 mm broad below, acuminate, sparsely puberulous, ciliolate. Petals five, 3.5-4 mm long, 1-1.2 mm broad, oblong, sub-acute, margins of limb somewhat serrulate. Claw transversely bearded, ciliate. The beard and cilia enclose the reproductive parts of the flower in a delicate cage. Staminodes five, 0.2 mm diam., vestigial, a sessile spherical gland at the apex of each lobe of the disc. Filaments five, becoming 1.2 mm long after anthesis, bearing a very few minute hairs. Anthers five, before anthesis 1.1 mm long, 0.75 mm broad, wine coloured, with a minute apical gland. Pollen 37-45µ long, 23-22µ diam., oblong. Disc 10-sinuate, green, stands open, exceeds the ovary, exudes nectar. Stigma 0.2 mm diam., capitellate, globose, green. Style 1.6 mm long, erect, glabrous, the lower half not shrinking so much when withered. Ovary 5-carpellate. 0.5 mm long, 0.7 mm diam., with one or at most two small hairs on each lobe. Fruit 5-carpellate, 13 mm long. Glabrous, gland-dotted, striate veined with horns 7 mm long, erect, slender. Seed 5-6 mm long, black, shining.
