Description Ces­pitosa. Tallos fértiles 20–70(200) cm, lisos, agudamente trígonos. Hojas (2)4–7(12) mm de anchura, de menor longitud que los tallos, planas, ásperas en los bordes, ± rígidas; lígula hasta 1,5–3(5) mm, de ápice obtuso; sin antelígula; vainas basales escuamiformes, pardas, enteras, rara vez un poco fibrosas. Bráctea inferior folíacea, de menor longitud que la inflorescencia, muy raramente algo mayor, con una vaina de hasta 20 mm. Espigas masculinas 1–3(–7), de 14–45 mm, fusiformes, a veces con algún utrículo en la base y ocasionalmente alguna ginecandra; espigas femeninas 3–4, de (10)30–50(75) mm, estrechamente cilíndricas, separadas o las superiores agrupadas, con largos pedúnculos filiformes, colgantes. Glumas masculinas oblongas u obovadas, agudas, subagudas u obtusas, raramente con un mucrón corto, de color pardo; glumas femeninas ovadas, de menor longitud que los utrículos, verdosas, hialinas o excepcionalmente blanco pardo muy pálido con ancho margen escarioso. Utrículos (3,8)4,5–5(5,3) × 1–1,2(1,5) mm, suberectos, ovoides, trígonos, verdosos o parduscos, con sólo 2 nervios prominentes, aunque en ocasiones se hace visible alguno más, bruscamente estrechados en un pico de 1,2–1,2 mm, bífido, liso o raramente con acúleos dispersos. Aquenios (2,2)2,5 × 0,9–1,4 mm, de contorno oval, trígonos (excepcionalmente descritos cuadrangulares), de color verdoso o pardo claro. [details]

Leaves 5–60 cm × 3–7(–11) mm, with c. 17–31(–37) veins, soft, slightly keeled or plicate, slightly tapered towards base, abruptly tapered to a sharp apex, mid green to yellow-green, becoming brown and then bleached on dying, overwintering; hypostomous; sheaths hyaline, becoming chestnut-brown, with inner face splitting and persisting as brown membrane; apex concave; ligule 2–4 mm long, obtuse, with free portion c. 0.25–0.4 mm wide. Inflorescence 1/3–1/2 length of stem; lowermost bracts leaf-like, sometimes longer than inflorescence, upper setaceous and shorter than spike. Male spike usually 1, 1–4 cm, very slender; male glumes 4–5 mm, oblong-oblanceolate, brown-hyaline; apex acute or obtuse and mucronate. Female spikes 3–5, ± distant, 2–6.5 cm, lax-flowered, often pendent; peduncles rough, filiform, up to three times the length of the spike, with base ensheathed; female glumes 3–5 mm, ovate-lanceolate, hyaline, straw-coloured or brown, with green midrib; apex acute or acuminate.

Description Plants densely cespitose. Culms pale brown to ivory at base, sometimes with a few brown fibrillose remains of previous year’s leaves, but not densely covered with fibrils; flowering stems 25–110(–200) cm, longer than leaves at maturity, 1–1.3 mm thick, glabrous. Leaves: sheaths glabrous, proximal ones ivory grading distally to light green, all bearing blades, pale hyaline on front; blades flat, (3–)5.5–8.5(–15) mm wide, glabrous on both surfaces, finely scabrous on margins. Inflorescences: peduncles of lateral spikes 5–20 mm, scabrous; peduncle of terminal spike less than 20 mm, scabrous; proximal bracts usually shorter than entire inflorescence; sheaths 20–100 mm; blades 2–3 mm wide. Lateral spikes: 3–5, 1 per node, the proximal well separated, erect to somewhat nodding, distal ones crowded near apex; proximal spikes pistillate with 15–40 spreading perigynia attached 1–1.5 mm apart, cylindric to elongate, 15–60 × 3–5 mm; distal spikes staminate or androgynous. Terminal spike staminate or androgynous with a few pistillate flowers at base, 15–40 × 2.5–3 mm. Pistillate scales white-hyaline with broad green midrib, oblong-lanceolate, shorter than mature perigynia, apex acute, cuspidate, or awned, glabrous. Perigynia green maturing to light brown, conspicuously 2-ribbed but otherwise veinless except for short inconpicuous veins at base, substipitate, tightly enveloping achene, obovoid, 4.5–6 × 1.4–1.8 mm, membranous, apex abruptly narrowed to tubular beak, glabrous; beak bidentate, slender, 2–3 mm, teeth 1 mm.

Male glumes oblong or obovate, acute, subacute or obtuse, rarely with a short mucro, brown; female glumes ovate, shorter than the utricles, greenish, hyaline or exceptionally very pale whitish-brown with a broad scarious margin. Utricles (3.8)4.5–5(5.3) × 1–1.2(1.5) mm, suberect, ovoid, trigonous, greenish or brownish, with only 2 prominent nerves, though occasionally an additional one may be visible, abruptly narrowed into a 1.2–1.2 mm beak, bifid, smooth or rarely with scattered prickles.
