Description Rhizomes far-creeping; shoots tufted; roots red-brown, up to 2 mm thick, much branched; scales orange- or red-brown, persistent. Stems 20–110 cm, smooth, bluntly trigonous above, subterete at base, brittle. Leaves 15–130 cm × 2.5–5(–8) mm, smooth, shiny, dark green or yellow-green beneath, rough or smooth and ± glaucous above; culm leaves flat, vegetative leaves weakly keeled, gradually tapered to a flat point, with margins rolling inwards on drying; epistomous, with a few scattered stomata below; sheaths herbaceous, wine-red or red-brown, persistent, with inner face hyaline, soon decaying; apex straight or concave; ligule 4–15 mm, obtuse or acute, ± tubular. Inflorescence 1/6–1/3 length of stem; bracts leaf-like, lowest conspicuously broad and ensheathing at base, exceeding inflorescence. Male spikes 2–4, 5–50 mm; male glumes 3–4 mm, obovate to oblanceolate, hyaline at margins; apex obtuse. Female spikes 2–5, 15–70 mm, cylindric, slender, dense-flowered, becoming lax below; upper contiguous, ± sessile, often male at top; lowest ± distant, ensheathing much of the spike; peduncles > 20 mm, smooth; female glumes 2–3 mm, ovate or broadly elliptic, hyaline at margins; apex acute to cuspidate or obtuse. Utricles 2–3 mm, ellipsoid to obovoid, nerveless, green; beak almost absent, truncate; stigmas 2; nut ellipsoid to obovoid, biconvex, shiny. [details]

Description Plants not cespitose. Culms 20–150 cm. Leaves: basal sheaths red-brown or brown; sheaths of proximal leaves glabrous, fronts with indistinct spots, veinless, apex U-shaped; blades usually amphi-stomic, papillose on both surfaces. Inflorescences: proximal bract longer than inflorescence. Spikes: erect; proximal 2–6 spikes pistillate; terminal (1–)2–4 spikes staminate. Pistillate scales red-brown to purple-brown, apex obtuse or acute, awnless. Perigynia ascending, veinless, somewhat flattened, loosely enclosing achenes, ellipsoid or obovoid, dull, apex obtuse or acute, papillose. Achenes not constricted, glossy. 2n = 72–80. [details]
