Shrubs, erect, sparsely branched, forming dense clumps <sometimes with prop roots>, to 40 dm, <bark smooth and metallic-silvery, without laticifers, exfoliating in thin, curled plates>. Stems: internodes 4-lined at first, soon 4-angled, then terete, <dull silvery, glaucous>. Leaf blades linear-subulate to acicular, (9–)12–17 × 0.5–0.8 mm, <glaucous>, base articulated, parallel or almost so, margins revolute, apex obtuse to rounded, midrib unbranched. Inflorescences <narrowly cylindric>, 1–3-flowered, usually with paired flowers or triads from to 9 proximal nodes. Flowers 20 mm diam.; sepals deciduous, not enclosing capsule, 5, linear-subulate, subequal, 7–8 × 0.5–0.8 mm, <glaucous>; petals 5, bright yellow, obovate-spatulate, 10–12 mm; stamens deciduous, 170–220; ovary 3-merous; <styles 5 mm>.
