DIAGNOSTIC DESCRIPTION
Shrub or shrublet 0.2-2.5 m tall, erect or rarely decumbent and rooting at the base, with branches strict, lateral or sometimes pseudo-dichotomous. Stems orange- brown, 4- angled and ancipitous when young, soon 2-lined, eventually terete, cortex exfoliating irregularly; internodes 1.5-10 mm long. Leaves sessile, not or scarcely imbricate, erect to spreading and twisting, not or scarcely tetrastichous, deciduous above base without fading; lamina 6-14 x 0-1.5 mm, linear to acicular, rarely cucullate, midrib impressed beneath, margin narrowly hyaline, concolorous, rarely glaucous, coriaceous to subcoriaceous; apex acute, base parallel-sided, scarcely broadening, pairs forming narrow interfoliar ridge; basal vein 1, unbranched; laminar glands dense to sparse, sometimes visible beneath. Inflorescence 1-flowered, terminal (usually) and on up to 12 short lateral shoots, sometimes with pseudo-dichotomous branches from terminal node; pedicel 0.5-3 mm long, not incrassate upwards; upper leaves transitional. Flowers 4-12 mm in diam., stellate to obconic. Sepals 2.5-7 x 0.5-2 mm, narrowly lanceolate, acute, veins 5, unbranched, midrib not prominent, margin hyaline; glands linear, sometimes distally punctiform. Petals bright to pale yellow, (3-)4-9 x l.5-3(-3.5) mm, 1.3-2.1 x sepals, narrowly oblong-obovate to obovate; apiculus acute to apiculate; glands mostly linear to mostly punctiform. Stamens 20-75, 3-5 mm long, longest 0.5-0.75 x petals. Ovary 0.8-3 x 0.6-1.8 mm, broadly ellipsoid or broadly ovoid to globose; styles 3-5(6), 1-3 mm long, 0.5-1.5 x ovary, ascending; stigmas narrowly to broadly capitate. Capsule 2.5-4 x 2-3 mm, ovoid-subglobose to globose, shorter than sepals. Seeds 0.6-1.2 mm long, ecarinate; testa finely scalariform.
