Subshrub (? or annual herb) 0.3-1 m tall, erect, 1-stemmed with branches divaricate-ascending, lateral, numerous, becoming naked below. Stems vinous? red, 4-lined, and ancipitous when young, eventually terete, cortex exfoliating in strips; internodes (5-)10-90 mm long, shorter to longer than leaves. Leaves sessile, spreading; lamina 8-30 x 2-7(-ll) mm, narrowly elliptic to narrowly oblong or rarely lanceolate, plane, usually paler beneath, not glaucous, chartaceous; apex acute to rounded, base cuneate, not decurrent, free; basal or near-basal veins 3-9, midrib with 2-c. 9 pairs of branches, tertiary reticulum dense (usually obscure) or absent (?); laminar glands dense, not prominent. Inflorescence c. 9-17 (-24)-flowered, dichasial/monochasial, sometimes with short accessory branches from terminal node, with lateral branches from up to 8 nodes below, the whole narrowly cylindric to narrowly or broadly pyramidal; primary pedicels 2-6 mm long; bracts and bracteoles narrowly lanceolate to linear. Flowers 10-15 mm in diam., stellate; buds narrowly ovoid, acute to rounded. Sepals 3.5-6 x 0.7-2 mm, subequal, basally imbricate, linear-lanceolate to ovate-lanceolate, acute; veins 5(3), all becoming prominent; glands linear. Petals yellow, 5-8 x 2-4.5 mm, 1.3-1.5 x sepals, narrowly obovate-oblong; apiculus acute; glands linear. Stamens c. 75, 5-fascicled, longest 3-4.5 mm long. c. 0.6 x petals. Ovary 1.5-2 x 0.8-1.1 mm, narrowly ellipsoid; styles 5 (or very rarely 4), 2-2.5 mm long, 1.2-1.35 x ovary, spreading-incurved; stigmas slightly enlarged to narrowly capitate. Capsule (5-)6 x (2.5-)3 mm, cylindric or rarely ovoid-cylindric, almost always exceeding sepals. Seeds 0.5-0.6 mm long; testa finely ribbed-scalariform.
