Shrubs, more than 0.5 m tall; branches ± ascending. Stems persistently 4-angled or narrowly 4-winged; internodes 1-2.5 cm, shorter than leaves. Leaves sessile; blade narrowly elliptic to lanceolate or narrowly oblong-elliptic, 1.9-7 × 0.5-1.6 cm, thickly papery, abaxially paler but not glaucous; laminar glands dots, prominent; abaxial glands absent; main lateral veins 2- or 3-paired, sometimes forming intramarginal vein, tertiary reticulation faint or nearly invisible; base cuneate, apex acute to subacute or rounded-apiculate. Inflorescence 1-flowered, terminal and on short subsidiary branches from up to ca. 6 nodes below; bracts leaflike, bracteoles leaflike to subulate, entire, deciduous. Pedicels 6-12 mm. Flowers ca. 2.5 cm in diam., substellate; buds ovoid, apex acute. Sepals free or nearly so, erect, subequal to unequal, oblong-linear to elliptic or oblanceolate, 5-8 × 1-2(-3) mm, laminar glands mostly lines, margin entire, apex subacute to acute or short acuminate. Petals bright yellow, tinged red, obovate, 1-2 cm × ca. 6 mm, 1.5-2 × as long as sepals; margin entire, eglandular; apiculus obsolete. Stamen fascicles each with ca. 25 stamens, longest 9-10 mm, ca. 0.8 × as long as petals. Ovary ± narrowly ovoid, 2-4 × 0.7-1.3 mm; styles (3.3-)4-7 mm, 2-2.5 × as long as ovary; stigmatic mass capitate. Capsule narrowly ovoid to cylindric, 7-9 × 3-4 mm, ca. 2 × as long as sepals. Seeds dark yellowish brown. 0.9-1.1 mm, with long terminal expansion; testa linear-reticulate. Fl. Mar-Jul, fr. Aug-Jan.
