Stems red-brown to green, persistently 4-lined, ancipitous when young, cortex persistent (always); internodes 15-65 mm long, shorter to longer than leaves. Leaves sessile, suberect or spreading; lamina 15-45(-50) x 5-15 mm, narrowly oblong or elliptic-oblong to ovate-lanceolate or oblanceolate, margin plane or usually basally to wholly recurved, paler beneath, not glaucous, chartaceous; apex acute to rounded, base cuneate to cordate, decurrent-amplexicaul, forming deep V, free; basal or near-basal veins 3-5, midrib with numerous to 2 pairs of branches, tertiary reticulum dense, sometimes obscure; laminar glands dense to rather sparse, obscure, not prominent. Inflorescence l-7(-17)-flowered, dichasial/monochasial, with- out accessory branches, with lateral branches from up to 8 nodes below, the whole narrowly cylindric to narrowly (or rarely broadly) pyramidal; primary pedicels 1.5-4 mm long; bracts and bracteoles linear-lanceolate to linear-oblong. Flowers (12-)15-25 mm in diam., stellate; buds ellipsoid, subacute. Sepals 5-11 x l-2(-2.7) mm, equal, scarcely imbricate, linear-lanceolate to lanceolate, acute to subacuminate; veins 3-7, only midrib or sometimes all becoming prominent; glands linear. Petals yellow to orange, 7-16 x 3.5-6 mm, c. 1-4 x sepals, oblanceolate or oblong-oblanceolate to obovate; apiculus acute; glands linear, distally striiform to punctiform. Stamens 70-80, obscurely 5-fascicled, longest 3.5-5.5 mm long, 0.35-0.5 x petals. Ovary 2-3 x 1.5-2 mm, broadly ovoid; styles 5(4), 2.5-3 mm long, 1-1.25 x ovary, spreading; stigmas clavate to narrow. Capsule 4.5-6 x 4.5-5 mm, broadly ovoid to subglobose, shorter than or equalling sepals. Seeds c. 0.5 mm long; testa ribbed-scalariform.
