DIAGNOSTIC DESCRIPTION
Suffrutex 0.09-0.15 m tall, erect or ascending from creeping branching and rooting base, forming dense Polytrichum-like rounded clumps, with branches strict, pseudo-dichotomous and lateral. Stems orange-brown, 4-angled and(?) ancipitous when young, soon terete, cortex exfoliating irregularly; internodes 1.3-5 mm long. Leaves sessile, imbricate, eventually outcurving and slightly twisting, tetrastichous, deciduous above base without fading; lamina 3-5 x 0.x-0.8 mm [ch], linear-subulate, incurved-canaliculate, cucullate, midrib impressed beneath or not, margin narrowly hyahne, concolorous, not glaucous, chartaceous; apex subacute to obtuse, base gradually broadened and sheathing, pairs forming relatively broad interfoliar ridge; basal vein 1, unbranched; laminar glands dense, visible beneath. Inflorescence 1-flowered, terminal, with pseudo-dichotomous branches from node below; pedicel c. 1 mm long, relatively stout; upper leaves not transitional. Flowers 6-8 mm in diam., obconic (?). Sepals 3-5 x 0.7-1.3 mm, narrowly oblong to narrowly oblong-lanceolate, acute, incurved above, margin hyaline, veins 3-5, unbranched, midrib or all prominent; glands all linear or distally punctiform. Petals bright yellow, 3.5-6.5 x 1.5-3 mm, c. 1.2-1.4 x sepals, obovate; apiculus acute or obsolete; glands striiform. Stamens 20-35, longest 2.5-3 mm long, c. 0.75 x petals. Ovary 0.8-1 x 0.6-0.8 mm, ellipsoid; styles 3, 1-1.2 mm long, c. 1.2 x ovary, erect; stigmas narrowly to broadly capitate. Capsule 4-4-. x 2-2.5 mm, cylindric- ellipsoid, subacute to obtuse, slightly exceeding sepals. Seeds not seen.
