Description Densamente cespitosa, con rizoma endeble. Tallos fértiles (6)15-65(80) cm, trígonos, con los ángulos romos. Hojas 0,5-2 mm de anchura, pero hasta de 4 mm de anchura cuando planas, de mayor longitud que los tallos, generalmente lisas, enrolladas o canaliculadas, muy raramente planas, ± rígidas, verdes o algo glaucas; lígula hasta 2 mm, cuya anchura puede superar la del limbo, de ápice redondeado y márgenes libres frecuentemente teñidos de rojo; sin antelígula; vainas basales de color pardo claro u obscuro, enteras, muy raramente algo fibrosas. Bráctea inferior similar a las hojas, de longitud mucho mayor que la inflorescencia. Espiga masculina solitaria, de 6-20(26) × 1-3(4) mm, cortamente cilíndrica o fusiforme; espigas femeninas 3-5, de 6-20(27) × 3-5,5(7) mm, ovoides, aproximadas a la masculina, aunque a veces la inferior esta separada, erectas. Glumas masculinas ovales u oblongas, de ápice variable y color pardo claro u obscuro; glumas femeninas ± ovales, generalmente agudas, a veces cortamente mucronadas, de color pardo claro u obscuro. Utrículos 3-3,6 × 1,1-1,5 mm, de contorno oval, suberectos (rara vez erecto-patentes o casi patentes), plurinerviados, mates, atenuados en un pico de 0,5-0,6 mm, cortamente bidentado, liso. Aquenios 1,9-2,5 × 1-1,3 mm, de contorno elíptico, trígonos. 2n = 60. [details]

Description Densely tufted, with a slender rhizome. Fertile stems (6)15–65(80) cm, trigonous, with blunt angles. Leaves 0.5–2 mm wide, but up to 4 mm wide when flat, longer than the stems, generally smooth, rolled or canaliculate, very rarely flat, ± rigid, green or somewhat glaucous; ligule up to 2 mm, its width sometimes exceeding that of the blade, with rounded apex and free margins frequently tinged red; without contraligule; basal sheaths light or dark brown, entire, very rarely somewhat fibrous. Lowest bract similar to the leaves, much longer than the inflorescence. Male spike solitary, (6)6–20(26) × 1–3(4) mm, shortly cylindrical or fusiform; female spikes 3–5, 6–20(27) × 3–5.5(7) mm, ovoid, close to the male spike, though sometimes the lowest one separated, erect. Male glumes oval or oblong, with variable apex and light or dark brown color; female glumes ± oval, generally acute, sometimes shortly mucronate, light or dark brown. Utricles 3–3.6 × 1.1–1.5 mm, oval in outline, suberect (rarely erect-patent or almost patent), plurinerved, dull, attenuate into a beak 0.5–0.6 mm, shortly bidentate, smooth. Achenes 1.9–2.5 × 1–1.3 mm, elliptic in outline, trigonous. 2n = 60. [details]
