Suffrutex, 3-9 m tall, canescent, divaricately branched; branchlets rigid, densely stellate-scaly, glabrescent in parts. Leaves small, 2.4 mm long, 0.5-1 mm broad, opposite and in axillary fascicles, the opposite leaves amplexicaul, deltoid from a broad base, the fascicled leaves oblong and cuneate, all scaly-canescent (the scales stellate). Flowers in terminal racemes, opposite, solitary in the axils of opposite leafy bracts which are amplexicaul and united at the base. Pedicels suberect, bi-bracteolate midway or near the base or apex, about 5 mm long, glabrous or scaly-canescent at least in the lower half. Calyx glabrous without, or partly scaly, glabrous within; tube more or less campanulate, about 1 mm long; lobes 4 (sinuses narrowly rounded), about 15 mm long, more or less deltoid, rounded at the apex. Corolla white, glabrous without, or the lobes scaly dorsally; tube 3 mm long, with scattered patent short gland-tipped hairs within; lobes about 4 mm long, broadly rounded at the apex. Stamens inserted near the mouth of the tube, free portion of filaments about 3 mm long; anthers yellow, exserted, cells parallel, distinct. Capsule oblong, cylindric, about 3 mm long, faintly 2-lobed, exserted from the calyx for about half its length, valves splitting.
