Characteristics

Erect compact shrubs up to 1.5 m tall, many-stemmed from a woody rootstock. Branches shortly lanate soon becoming glabrous, often with distinct internodal sterigmata. Leaves 3-nate, appressed imbricate, narrowly ovate to narrowly elliptic to oblong, 1.0-1.8 x 0.4-0.8 mm, glabrous abaxially, pubescent adaxially mainly towards the base, long ciliate and pubescent all over when young and with an apical tuft which remains as strigulae; petiole puberulous abaxially when young, often glabrescent but with some long hairs remaining. Flowers 1-3(6)-nate on the ends of short lateral brachyblasts crowded at the ends of the branches; pedicel 1.5-1.7 mm long, puberulous, green; bract fully recaulescent; bracteoles wanting. Calyx 4-lobed, green; larger lobe 0.7-0.8 mm long, narrowly triangular to subspathulate from a broadened base; remaining lobes 0.6-0.8 mm long, more or less triangular; all lobes ciliate, the smaller ones pubescent on the inner surface, sulcate at the apex, the larger ones more so. Corolla 4-lobed, 1.2-1.8 x 1.0-1.3 mm, broadly obovoid, greenish yellow soon turning pale brown and papery; lobes broad, rounded, partially cucullate sometimes emarginate. Stamens 4, free, included; filaments 0.3-0.6 mm long, linear, expanded at the apex, glabrous, 1/3-1/2 the length of the anther; anthers 0.5-1.1 mm long ellipsoid to obovoid, seated on top of the ovary, glabrous, muticous to distinctly aristate, awns up to 0.2 mm long, partially decurrent; pore 1/4-1/3 the length of the thecae. Ovary 3-celled, 0.5-0.8 mm long, broadly ellipsoid to globose, ridged longitudinally in the upper half, lanate above and mainly down the ridges; style 0.6-0.9 mm long, glabrous; stigma infundibuliform, 0.4-0.7 mm in diam., manifest to slightly exserted. Fruit a dehiscent loculicidal capsule 1.0-1.2 mm long, sparsely lanate with well developed septa at the base 1/3-1/2 the length of the capsule; seeds narrowly ellipsoid, 0.75 x 0.42 mm with reticulate testa of elongate sunken cells with irregularly undulate margins.
