DIAGNOSTIC DESCRIPTION
Shrublet up to 0.15 m tall, prostrate or ascending, forming tufts up to 150 mm in diam., with branches pinnate, spreading. Stems orange-brown, 6-lined and compressed when young, the subfoliar ridges broad, eventually terete, cortex splitting between and below subfoliar ridges; internodes c. 0.5 mm long. Leaves sessile, densely to loosely imbricate, tetrastichous, deciduous above base or more usually only with the cortex after fading; lamina 4-7 x 0.5-0.8 mm, linear, incurved-canaliculate, cucullate, midrib impressed beneath, margin broadly hyaline, concolorous, sublucent beneath, sublucent to dull above, sometimes subglaucous, coriaceous; apex acute to subacute, base parallel-sided, not sheathing, pairs united to form narrow interfoliar ridge; basal vein 1, unbranched; laminar glands dense above, rather sparse or absent beneath. Inflorescence 1-flowered, with pseudo-dichotomous branches from node below and also short congested lateral branches (racemiform); pedicel absent or up to 2 mm long; upper leaves not transitional. Flowers c. 8 mm in diam., stellate. Sepals 3-4 x 0.8-1.2 mm, oblong to triangular- lanceolate (equal), acute, cucullate, margin broadly hyaline; veins 3(5?), unbranched, slightly prominent; glands mostly linear. Petals bright yellow, tinged red outside, 4.5-6 x 2-2.5 mm, 1.5 x sepals, obovate-oblong; apiculus very short or almost absent; glands linear, distally punctiform. Stamens c. 13, longest 3-4 mm long, c. 0.65 x petals. Ovary 1.5-2.5 x 1.5-2 mm, subglobose; styles (3)4-5, 0.8-1 mm long, 0.4-0.5 x ovary, outcurved; stigmas broadly capitate. Capsule c. 3 x 3 mm, cylindric-globose to globose, shorter than sepals. Seeds 0.7-0.8 mm long, ecarinate; testa finely scalariform.
