Herbs perennial, erect, unbranched or branching at base and in inflorescence, 4–7.5 (–10) dm. Stems: internodes 4-lined. Leaves (main-stem) ascending to spreading, sessile; blade lanceolate to oblongelliptic or obovate, 10–30 (–50) × 3–8 (–12) mm, on main-stem, longer than internodes, leathery, margins plane, apex usually acute to acuminate, rarely obtuse, basal veins 1–3+, midrib with 2–3 pairs of inconspicuous branches. Inflorescences broadly cylindric to corymbiform, 25–70-flowered, branching mostly dichasial, subsidiary branches with or without relatively smaller leaves. Flowers 8–13 mm diam.; sepals narrowly ovate to lanceolate, equal, 3–3.5 × 1.5–2.5 mm, margins sometimes ciliate, not setulose-ciliate, apex acute to acuminate; petals orange-yellow, obovate, 6–10 mm; stamens 50–80, irregularly grouped; styles 2–4 mm; stigmas capitate. Capsules ovoid to rostrate-subglobose, 3–5 × 2–3 mm. Seeds (0.5–) 0.6–0.8 (–0.9) mm; testa reticulate. 2n = 24.
