Description Densamente cespitosa, con rizoma no muy grueso. Tallos fértiles 3–20(30) cm, gruesos, obtusamente trígonos, lisos. Hojas hasta 3,5(4) mm de anchura, de menor longitud que los tallos, bastante rígidas, planas o con sección transversal en forma de “V”, escábridas en los márgenes en la mayor parte de su longitud, de color verde claro; lígula hasta 2 mm, con el ápice variable, de anchura menor que el limbo; antelígula 0,5–3 mm, de ápice obtuso; vainas basales enteras o algo rotas, pero nunca deshechas en fibras, de color pardo generalmente oscuro. Bráctea inferior folíacea frecuentemente de longitud igual o mayor que la inflorescencia. Espiga masculina solitaria, de 6–12(17) × 1,8–2,5(3) mm, estrechamente cilíndrica o fusiforme; espigas femeninas 2–4, de 6–13(15) × 2,3–5 mm, ± ovoides o cortamente cilíndricas, las superiores generalmente aproximadas, la inferior surge frecuentemente de la zona basal del tallo, casi sésiles o con pedúnculos que superan la vaina hasta 4,5 mm, erectas. Glumas masculinas ovadas, con el ápice generalmente redondeado, de color rojo-púrpura oscuro en su juventud, aunque claramente claras cuando la planta madura; glumas femeninas ovadas, emarginadas o, más frecuentemente, con un micrón que apenas supera la escotadura, de color pardo-rojizo a pardo-púrpura oscuro, con el nervio medio verde. Utrículos (2)2,2–2,3(3,2) × 1–1,4(1,8) mm, suberectos, de contorno oval, obovados o elípticos, teñidos de rojo en numerosas ocasiones, con sólo 2 nervios marginales, estrechados bruscamente en un pico de 0,4–0,6(0,9) mm, bidentado, densamente aculeolado. Aquenios 1,5–2,1 × 0,9–1,3 mm, de contorno obovado, trígonos, pardos, con la base del estilo persistente en forma de una corta columna. 2n = 34. [details]

Description Densely tufted, with a not very thick rhizome. Fertile stems 3–20(30) cm, thick, obtusely trigonous, smooth. Leaves up to 3.5(4) mm wide, shorter than the stems, rather rigid, almost flat or with a V-shaped cross section, scabrous on the margins along most of their length, light green in color; ligule up to 2 mm, with a variable apex, narrower than the blade; antiligule 0.5–3 mm, with a ± obtuse apex; basal sheaths entire or somewhat torn, but never fibrous, usually dark brown. Lower bract leaf-like, often as long as or longer than the inflorescence. Male spike solitary, 6–12(17) × 1.8–2.5(3) mm, shortly cylindrical or fusiform; female spikes 2–4, 6–13(15) × 2.3–5 mm, ± oval or shortly cylindrical, the upper ones generally close together, the lower one often arising from the basal part of the stem, almost sessile or with peduncles exceeding the sheath by up to 4.5 mm, erect. Male glumes obovate, apex usually rounded, dark reddish-purple when young, becoming paler as the plant matures; female glumes oval, emarginate or more often with a mucro barely exceeding the notch, reddish-brown to dark purple-brown, with a green midrib. Utricles (2)2.2–2.3(3.2) × 1–1.4(1.8) mm, suberect, oval in outline, obtusely trigonous, often tinged red, with only 2 marginal nerves, abruptly narrowed into a beak 0.4–0.6(0.9) mm, bidentate, densely aculeolate. Achenes 1.5–2.1 × 0.9–1.3 mm, elliptical in outline, trigonous. 2n = 68. [details]

Translation Densely cespitose, with a not very thick rhizome. Fertile stems 3–20(30) cm, stout, bluntly trigonous, smooth. Leaves up to 3.5(4) mm wide, shorter than the stems, rather rigid, flat or with a V-shaped transverse section, scabrid along the margins over most of their length, light green; ligule up to 2 mm, with a variable apex, narrower than the blade; antiligule 0.5–3 mm, with an obtuse apex; basal sheaths entire or somewhat torn but never fibrous, generally dark brown. Lower bract foliose, frequently as long as or longer than the inflorescence. Male spike solitary, 6–12(17) × 1.8–2.5(3) mm, narrowly cylindrical or fusiform; female spikes 2–4, 6–13(15) × 2.3–5 mm, ± ovoid or shortly cylindrical, the upper ones usually approximate, the lowest often arising from the basal part of the stem, almost sessile or with peduncles protruding up to 4.5 mm from the sheath, erect. Male glumes ovate, with the apex usually rounded, dark reddish-purple when young but clearly paler at maturity; female glumes ovate, emarginate or more often with a small mucro barely exceeding the notch, reddish-brown to dark purplish-brown, with a green midrib. Utricles (2)2.2–2.3(3.2) × 1–1.4(1.8) mm, suberect, oval, obovate or elliptic, often reddish-tinged, with only two marginal nerves, abruptly narrowed into a 0.4–0.6(0.9) mm beak, bidentate, densely aculeolate.
