Description Laxamente cespitosa, con rizoma muy robusto, con algunos entrenudos largos. Tallos fértiles 40–100(150) cm, escábridos en la zona superior, agudamente trígonos. Hojas (4)7–10(19,5) mm de anchura, generalmente de longitud similar a la de los tallos, planas o plegadas, muy ásperas en los bordes y en el nervio medio del envés, ± rígidas; lígula 5–12 mm, de ápice obtuso, con los bordes libres, a veces algo levantados; sin antelígula; vainas basales con limbo desarrollado, solo las más inferiores escuamiformes, de color pardo, enteras. Bráctea inferior folíacea, de mayor longitud que la inflorescencia, rara vez no envainante o con una vaina hasta de 10 mm. Espigas masculinas 2–4(6), de (9)20–40(60) mm, achamente cilíndricas o fusiformes, a veces la inferior con algunos utrículos en la base; espigas femeninas 2–5(7), de (23)30–70(110) mm, a veces laxas, distantes, erectas, la inferior generalmente con un largo pedúnculo colgante. Glumas masculinas estrechamente ovales, mucronadas o aristadas, de color pardo oscuro, sin margen escarioso; glumas femeninas de lanceolado-oblongas a estrechamente ovales, aristadas o mucronadas, generalmente de longitud mayor —en ocasiones algo menor— que los utrículos, de color pardo-rojizo o pardo-púrpura oscuro, sin margen escarioso, con tres nervios bien marcados.

Aquenios (2,1)2,5–3 × (0,9)1,3–1,5(1,9) mm, de contorno obovado, trígonos, raramente oval, de color pardo. 2n = 72*, 76*. [details]

Description Rhizome stout. Culms 60-150 cm tall, triquetrous, scabrous on upper part, clothed with brown or reddish brown sheaths at base. Leaves equaling or longer than culm, blades 10-15 mm wide, flat, ± stiff, with distinct and transverse septate nodes between veins, rather long sheathed.

Spikes 5-10, lower spikes remote and upper spikes approximate; terminal 3-6 spikes male, oblong-cylindric or cylindric, 2-6 cm, subsessile; remaining spikes female, cylindric, 3-6 × ca. 1 cm, densely many flowered, sometimes with male flowers at top, upper spikes subsessile, lower spikes slightly long pedunculate. Female glumes brown, lanceolate, ca. 6 mm, 3-veined, apical margins hispidulous, apex acuminate, mucronate. Utricles fuscous-green, obliquely patent, nearly equaling glume, elliptic-ovate, obtusely trigonous, 5-6 mm, leathery or slightly corky, glabrous, several veined, base cuneate, apex gradually narrowed to a slightly broad and short beak, orifice slightly divergent and shortly 2-toothed.

Translation Loosely caespitose, with a very robust rhizome bearing some long internodes. Fertile stems 40–100(150) cm tall, scabrid in the upper part, sharply trigonous. Leaves (4)7–10(19.5) mm wide, generally of similar length to the stems, flat or folded, very rough along the margins and the midrib on the abaxial surface, ± rigid; ligule 5–12 mm long, with an obtuse apex, free margins sometimes slightly raised; no antiligule; basal sheaths with a developed blade, only the lowermost ones scale-like, brown, entire. Lower bract leaf-like, longer than the inflorescence, rarely non-sheathing or with a sheath up to 10 mm long. Male spikes 2–4(6), (9)20–40(60) mm long, narrowly cylindrical or fusiform, sometimes the lowest with a few utricles at the base; female spikes 2–5(7), (23)30–70(110) mm long, sometimes lax, distant, erect, the lowest usually with a long pendulous peduncle. Male glumes narrowly ovate, mucronate or aristate, dark brown, without scarious margins; female glumes lanceolate-oblong to narrowly ovate, aristate or mucronate, generally longer—sometimes slightly shorter—than the utricles, reddish-brown to dark purplish-brown, without scarious margins, with three well-marked nerves. Utricles (3)4–5(6) × (1)1.5–2(2.9) mm, suberect, oval in outline, inflated, greenish or brownish, with the nerves well marked, sometimes very prominent, gradually narrowed into a beak 0.4–0.9(1.1) mm long, shortly bifid, with broadly rounded sinuses, smooth. Achenes (2.1)2.5–3 × (0.9)1.3–1.5(1.9) mm, obovate in outline, trigonous, rarely oval, brown. 2n = 72*, 76*. [details]
