Stems yellow to orange-brown, sharply 4-lined, ancipitous when young, cortex exfoliating in strips; internodes 2-14(-35) mm long, the upper sometimes exceeding leaves. Leaves sessile, spreading; lamina 3-15 x 0.5-1.5(-2) mm, narrowly oblong to linear, margin revolute, paler beneath, not glaucous, chartaceous, apex obtuse to rounded, base parallel-sided or usually cordate-amplexicaul, not decurrent, free; basal vein 1, sometimes with obscure lateral branches, tertiary reticulum absent; laminar glands dense, prominent beneath. Inflorescence 3-16-flowered, dichasial/monochasial, with lateral branches from up to 3 nodes below, the whole narrowly cylindric; primary pedicels 0.5-3 mm long; bracts and bracteoles triangular-lanceolate to linear-subulate. Flowers 8-12 mm in diam., stellate or slightly obconic; buds ovoid, acute to subacute. Sepals 3.5-4.5(-5) x 1.2-2.4 mm, unequal, imbricate, the outer broadly rhombic-elliptic or ovate-lanceolate to ovate, the inner ovate-lanceolate to lanceolate or oblong, acute to obtuse, margin sometimes recurved; veins 5, only midrib becoming prominent; glands linear, distally punctiform. Petals yellow, tinged red outside, 5-7 x 2.5-4 mm, 1.5-1.7 x sepals, oblong; apiculus obtuse; glands striiform to punctiform. Stamens c. 40-50 (or more?), obscurely 3-5-fascicled, longest (2-)3-4 mm long, 0.5-0.7 x petals. Ovary 1.5-2 x 1 mm, ovoid; styles (3-)4-5, 1-5-2-5 mm long, 1-1-35 x ovary, spreading; stigmas slightly enlarged to distinctly capitate. Capsule 3.5-5 x 2-4 m, ovoid to subglobose, about equalling sepals. Seeds 0.6-0.7 mm long; testa finely ribbed-scalariform.
