Description Rhizomes short and branched, with tufted shoots of two kinds: apical leafy shoots with overwintering terminal buds and lateral short shoots ending in a flowering stem; roots deep red-brown, wiry and fibrous; scales purplish-crimson. Stems 5–25 cm, slender, trigonous-subterete, with 2–4 short (up to 2 cm), often setaceous leaves at the base. Leaves 5–25 cm × 1.5–5 mm, usually sparsely hairy on the upper surface, soft, ± flat or slightly keeled, abruptly tapered to a blunt point, light green to bronzy-green, often overwintering; margins rough; hypostomous; sheaths bright crimson even in very young shoots, inner face herbaceous; apex concave, soon splitting; ligule 0.5–1.5 mm, rounded. Inflorescence 1/5–3/4 the length of the stem, the lowest branch 1 cm or more below the female spike; bracts up to 10 mm, sheathing for 3 mm. Male spike 1, overtopped by the uppermost female spike; male glumes 5 mm, red-brown with a pale midrib and hyaline margin, apex rounded or emarginate. Female spikes 1–2 cm, 5–10-flowered, peduncle < 6 mm; female glumes 3–4.5 mm, obovate, purplish-crimson, apex obtuse or emarginate. Utricles 3–4.5 mm, obovoid, greenish-brown, pilose; beak almost absent, truncate; stigmas 3; nut obovoid, trigonous, stalked. [details]

Description Cespitosa, a veces con rizomas de entrenudos algo alargados, ascendentes. Tallos (9)15–25(30) cm, obtusamente trígonos, lisos o algo escábridos en el ápice, laterales, sin hojas o con 1–2 reducidas a una vaina y un limbo poco desarrollado. Hojas (1)2–4(6) mm de anchura, de longitud mayor o menor que los tallos, ásperas en los bordes de la zona apical, planas, algo rígidas; lígula diminuta, con ápice obtuso o ± redondeado; sin antelígula; vainas basales con limbo desarrollado, de algo rotas a fibrosas, purpúreas, rojizas o de color pardo. Bráctea inferior glumácea, a veces con una punta setácea, envainante. Espiga masculina solitaria, de 6–13,5 mm, linear o estrechamente fusiforme; espigas femeninas (1)2–3, de (11)13–18(22) mm, las superiores agrupadas junto a la masculina, la inferior frecuentemente separada y con un pedúnculo hasta de 3,5 cm, erectas, lineares, laxas. Glumas masculinas ovales u oblongas, de ápice redondeado a truncado, de color pardo a veces muy oscuro, con ancho margen escarioso; glumas femeninas estrechamente obovadas, de ápice truncado o redondeado, en ocasiones mucronulado, de color pardo, con ancho margen escarioso, de longitud igual, mayor o algo menor que los utrículos. Utrículos 3,2–4 × 1–1,5 mm, suberectos, de contorno oval u obovado, trígonos, con los nervios muy poco perceptibles salvo los 2 laterales, pubescentes, estipitados, gradualmente atenuados en un pico de 0,2–0,3(0,5) mm, entero o cortamente bidentado. Aquenios 2,2–2,5 × (0,9)1–1,2 mm, de contorno elíptico, trígonos, pardo. 2n = 48*, 50*, 52*, 54*. [details]

Translation Caespitose, sometimes with rhizomes having somewhat elongated, ascending internodes. Culms (9)15–25(30) cm, obtusely trigonous, smooth or slightly scabrid at the apex, lateral, leafless or with 1–2 leaves reduced to a sheath and a poorly developed blade. Leaves (1)2–4(6) mm wide, longer or shorter than the culms, rough along the apical margins, flat, somewhat rigid; ligule minute, apex obtuse or ± rounded; antiligule absent; basal sheaths with a developed blade, somewhat torn to fibrous, purplish, reddish or brown. Lower bract glumaceous, sometimes with a setaceous tip, sheathing. Male spike solitary, 6–13.5 mm long, linear or narrowly fusiform; female spikes (1)2–3, (11)13–18(22) mm long, the upper ones clustered close to the male spike, the lower one often distant and with a peduncle up to 3.5 cm long, erect, linear, lax. Male glumes ovate to oblong, apex rounded to truncate, brown, sometimes very dark, with a broad scarious margin; female glumes narrowly obovate, apex truncate or rounded, occasionally mucronulate, brown, with a broad scarious margin, equal to, longer than, or slightly shorter than the utricles. Utricles 3.2–4 × 1–1.5 mm, suberect, oval to obovate in outline, trigonous, veins very weakly visible except for the two lateral ones, pubescent, stipitate, gradually attenuate into a beak 0.2–0.3(0.5) mm long, entire or shortly bidentate. Achenes 2.2–2.5 × (0.9)1–1.2 mm, elliptic in outline, trigonous, brown. 2n = 48*, 50*, 52*, 54*. [details]
