Shrub 0.2-1 m tall, erect, with branches very strict, pseudo-dichotomous and lateral. Stems reddish-brown, 2-lined and compressed when young, the subfoliar ridges broad, very soon terete, appearing articulated when old, cortex exfoliating at first in strips between subfoliar ridges; internodes 1-1.5 mm long. Leaves petiolate with short petiole (c. 0.5 mm long), densely imbricate, markedly tetrastichous, deciduous above petiole without fading or with attached cortex below after fading; lamina 3-9 x 0.5-2 mm, very narrowly elliptic to linear, incurved to canaliculate, ± cucullate, midrib impressed beneath, margin narrowly hyaline, dull above, lucent beneath, not glaucous, coriaceous; apex acute, base angustate to above 'articulation' then broadening, pairs forming narrow interfoliar ridge; basal vein 1, unbranched; laminar glands dense, obscure, visible above only. Inflorescence 1-flowered, terminal and on lateral branches, sometimes with single or pseudo-dichotomous branches from node below; pedicel absent or up to 3 mm long, not or slightly incrassate upwards; upper leaves not transitional. Flowers 10-20 mm in diam., stellate to obconic. Sepals 5-6(-7) x 1-2 mm, subequal, lanceolate to oblong-lanceolate, acute to acuminate, cucullate, with margin narrowly hyaline; veins 3-7, unbranched, midrib not prominent; glands linear, uninterrupted. Petals deep? yellow to orange-yellow, 7-14 x 3.5-7 mm, c. 1.6 x sepals, oblanceolate; apiculus acute; glands linear, distally interrupted. Stamens 55, longest 4.5-6.5 mm long, c. 0.6 x petals. Ovary c. 2 x 1 mm, ovoid; styles 3, 3.5-4 mm long, 1.5-2 x ovary, diverging-incurved; stigmas subclavate. Capsule 5-7 x 2.5-3 mm, narrowly ovoid, shorter than sepals. Seeds c. 1 mm long, ecarinate; testa finely ribbed-scalariform.
