Stems green, 4-lined, densely gland-dotted, the lowermost portion often becoming brown and spongy-thickened; internodes 8-47 mm long, exceeding leaves. Leaves sessile, spreading from base or usually ascending to appressed, mostly shorter than internodes; lamina 4-20(24) x 3-18 mm, lanceolate or ovate to elliptic or oblong-elliptic or obovate, margin plane but sometimes recurving when dry, concolorous or almost so, not glaucous, subcoriaceous; apex acute to subrounded, base cuneate to rounded-subamplexicaul, sometimes subdecurrent, free; basal veins 1-5, if 1 then with 2-3 pairs of main lateral branches, the midrib otherwise apparently unbran- ched, tertiary reticulation not visible; laminar glands dense on bthsides, not or scarcely prominent until dry. Inflorescence up to c. 25-flowered (terminal), monochasial after c. 4th grade, with up to c. 15-flowered lateral dichasial/monochasial branches from up to 6 nodes below, the whole broadly pyramidal to corymbiform, occasionally with lateral flowering branches below; pedicels 2-4 mm long; bracts 3-6 mm long, lanceolate to subulate. Flowers 5-13 mm in diam., stellate. Sepals 3-8 x 1.5-4 mm, ovate or lanceolate to elliptic or obovate, acute to acuminate; veins 3-5, rarely branched, all prominent; glands linear, distally punctiform. Petals orange-yellow, 5-10 x 4-6 mm, c. 1.6-2 x sepals, obovate; apiculus obtuse; glands linear, interrupted distally. Stamens 50-80, irregularly grouped, longest 3-5 mm long, c. 0.5-0.6 x petals. Ovary 1.5-2 x 1-1.5 mm, ovoid; styles 3, 2-4 mm long, 1.3-2 x ovary, divergent-incurved; stigmas capitate. Capsule 3-5 x 2-3 mm, ovoid to rostrate-subglobose, shorter than to shortly exceeding sepals. Seeds 0.45(0.5-0.65 mm long, testa obscurely linear-reticulate to finely ribbed-scalariform.
