Shrub 0.2-2 m tall, erect to ascending, with branches strict, lateral or more rarely pseudo-dichotomous. Stems orange-brown, 4-lined and ancipitous when young, eventually terete, cortex exfoliating irregularly; internodes 1.5-7 mm long. Leaves sessile, densely to loosely imbricate, erect, spreading and twisting, scarcely tetrastichous, deciduous above base without fading; lamina 6-12 x 0.8-1.7 mm, very narrowly oblanceolate to linear, incurved-cucullate, midrib impressed beneath, margin very narrowly hyaline, concolorous, not glaucous, coriaceous; apex acute, base parallel, not sheathing, pairs united to form narrow interfoliar ridge; basal vein 1, unbranched; laminar glands rather dense, few or sometimes none visible beneath. Inflorescence 1-flowered, rarely with pseudo-dichotomous branches from node below; pedicel 1.5-3 mm long, not incrassate upwards; upper leaves not transitional. Flowers 20-30 mm in diam., stellate. Sepals 7-11 x 1.5-2.5 mm, lanceolate, acute to acuminate, incurved above, margin hyaline, veins 5, midrib not prominent; glands linear, distally punctiform. Petals bright to deep yellow, 10-15 x 5-7 mm, c. 1.4 x sepals, oblong-oblanceolate; apiculus sharply acute to apiculate; glands striiform to punctiform, sparse. Stamens 60-75, longest 5-9 mm long, 0.5-0.6 x petals. Ovary 2-3.5 x 1.5-2 mm, ellipsoid-subglobose; styles 3(4), (2.5)3-4.5 mm long, (1.3)1.5 -2 x ovary, outcurving, slender; stigmas narrowly or not capitate. Capsule c. 5 x 3 mm, broadly ellipsoid to subglobose, shorter than sepals. Seeds c. 0-8 mm long (immature?), ecarinate; testa finely scalariform.
