Shrub compact subspreading, rarely sparse and erect, 150-250 mm tall, much branched single-stemmed reseeder. Branches: numerous main branches ending in inflorescences; occasional secondary branchlets not at every node, 3-6(-10) mm long, often cernuous, terminating in an inflorescence; stems covered with stiff dense short hairs and long gland-tipped hairs; internodes 2-4 mm long. Leaves 4-nate, usually subspreading but spreading in shady conditions, ±2.0 x 0.6 mm, narrowly elliptic-lanceolate, acute, adaxially and abaxially slightly rounded and flattened towards the base with rounded or subacute margins, covered with very short fine hairs, ciliate with a few long sticky gland-tipped hairs and one apically, sulcus narrow and open at base; petiole ±0.5 mm long, finely and shortly hairy. Inflorescence: flowers 4-nate in 2(1) whorls at ends of main and secondary branches, umbel-like; pedicel ±1.2 mm long, basally curved, finely hairy; bract partially recaulescent and approximate to the calyx, sometimes subapproximate, ±1.0 x 0.6 mm, elliptic, covered with short fine hairs at base and apex, margins with a few shortly stalked sticky glands and one larger one apically, green to dark red; bracteoles 2, approximate to calyx, ±0.8 x 0.6 mm, like the bract except the glands with shorter stalks. Calyx 4-partite; segments adpressed to the corolla, ±1.0 x 0.8 mm, ovate, greenish to dark purple, shortly and finely hairy in the mid and basal region, margins with large sticky glands these mostly sessile sometimes very shortly stalked, apical gland often larger. Corolla 4-lobed, ±2.0 x 1.8 mm, urceolate to cyathiform, dark purple occasionally paler, glabrous, very sticky; lobes erect to slightly spreading, ±0.5 x 1.0 mm, subacute to emarginate, entire. Stamens 8, free, included; filaments ±1.2 mm long, straight, glabrous, white; anthers bilobed, erect, dorsally attached, elliptic in outline adaxially, appendiculate, spurs narrow ±0.5 mm long, pointing adaxially, glabrous; thecae ±0.8 x 0.5 mm, obliquely elliptic in outline laterally, light brown, glabrous; pore two thirds length of theca; pollen in tetrads. Ovary 4-locular, ±0.5 x 0.7 mm, depressed globose, slightly emarginate, finely hairy to glabrescent, with no nectaries; ovules 3 or 4 per locule, suberect from a central placenta on the axis; style 0.8-1.2 mm long, manifest to exserted, glabrous; stigma large peltate, blackish purple. Fruit a dehiscent capsule, ±1 x 2 mm, valves spreading to 45-70°, septa equally on columella and valves; seeds ±0.7 x 0.4 mm, irregularly ellipsoid, shallowly reticulate, cells ±100-180 x 50-70 mm, with jigsawed anticlinal walls and numerous small pits in the inner periclinal walls.
