Shrublet, low sprawling, fairly dense, up to 0.25 m high, single-stemmed reseeder. Branches: numerous main branches, each branch with 4-6 secondary branchlets 5-15 mm long, all terminating in a pendulous inflorescence, all densely pubescent with retrorse simple hairs, occasionally interspersed with retrorse, stouter, plumose, nonsticky gland-tipped hairs. Leaves 3-nate, erect, imbricate, 2.0-2.5 x 0.5 mm, oblong to lanceolate, adaxially flattened, abaxially rounded and narrowly sulcate, edges acute and entire, glabrous, edged with reddish, small, nonsticky, very short-stalked glands in young leaves only; petiole 0.4 mm long, appressed, glabrous, edged with small sessile glands. Inflorescence: flowers 3-nate in 1 or 2 whorls, umbel-like and terminal on main and secondary branches; pedicel 1-2 mm long, glabrous except for a few scattered, short-stalked, nonsticky gland-tipped hairs and rarely with some simple hairs; bract recaulescent and approximate to the calyx, 1.1-1.6 x 0.4 mm, oblanceolate, as long as sepals, adaxially rounded and narrowly sulcate for 1/3 its length, glabrous, white, occasionally tinged green, glands as in leaf; bracteoles 2, approximate, 1.0 x 0.3 mm, otherwise like the bract. Calyx 4-partite, appressed to corolla; segments 1.1 x 0.4 mm, narrowly ovate-attenuate, abaxially rounded and narrowly sulcate about 1/3 their length, glabrous, edged with small, nonsticky, short-stalked glands. Corolla 4-lobed, ca. 1.2-1.8 x 2.5 mm, broadly cyathiform, colliculate, glabrous, white; lobes erect, very broadly triangular, subacute, minutely fimbriate to entire. Stamens 8, free, manifest; filaments 1 mm long, linear, straight, glabrous; anthers bilobed, dorsifixed near the base, oblong, erect, golden brown, muticous; thecae erect appressed, 0.8 x 0.25 mm, oblong, subfalcate, aculeate-edged and adaxially aculeate; pore 1/3-1/4 the length of theca; pollen as tetrads. Ovary 4-locular, 0.6 x 0.9 mm, oblate, slightly emarginate, slightly 4-lobed, glabrous, rarely with a few short stiff hairs, white, with dark-red nectaries around the base; ovules 3 per locule, pendulous from an apical placenta; style manifest, erect, straight, 0.9-1.2 mm long, terete, glabrous; stigma simple-truncate. Fruit a dehiscent capsule, 1.4 x 2.0 mm, cyathiform, with small apical placenta and remnant style-base, valves fused for 1/10 their length, spreading, septa only on the columella; seeds 0.8 x 0.5 mm, cuneate, trigonous, complanate, with subapical beak at point of attachment, reticulate-areolate, brown, cells irregularly subequal with straight anticlinal walls and numerous pits.
