Description Cespitosa. Tallos fértiles 2–20(40) cm, obtusamente trígonos, lisos, completamente rectos. Hojas 1–2,6(3,1) mm de anchura, de menor longitud que los tallos, lisas, de color verde claro, planas o algo canaliculadas, poco rígidas; lígula muy corta, con ápice frecuentemente oblicuo y truncado; antelígula hasta 0,5 mm, de ápice redondeado, muchas veces inexistente; vainas basales enteras, de color pardo. Bráctea inferior foliácea, de 2,4–13 cm × 0,9–2,2 mm, de mayor longitud que la inflorescencia. Espiga masculina solitaria, de 4–12(20) × 1–3,3 mm, cilíndrica o fusiforme, sésil o con un pedúnculo hasta de 20 mm; espigas femeninas 1–8, de 5–17 × 3–8 mm, cortamente cilíndricas a subglobosas, generalmente agrupadas bajo la masculina, muy rara vez la inferior separada e incluso subbasilar, sésiles o cortamente pedunculadas, erectas. Glumas masculinas lanceoladas o estrechamente ovales, agudas, obtusas o acuminadas, de color pardo rojizo claro u obscuro; glumas femeninas ± ovales, agudas u obtusas, de color pardo rojizo o pardo-rojizo claro, con 3 nervios. Utrículos (1,8)2,2–3 × 0,8–1,6 mm, los inferiores patentes o ligeramente reflejos, los de la mitad superior de patentes a erecto-patentes y los apicales con frecuencia erectos, subglobosos, de contorno obovado, plurinerviados, bruscamente estrechados en un pico de 0,3–0,8(1,3) mm, recto, bidentado, liso. Aquenios 1–1,6 × 0,7–1,3 mm, de contorno obovado, trígonos. 2n = 68*, 70?*. [details]

Male spike solitary, 4–12(20) × 1–3.3 mm, cylindrical or fusiform, sessile or with a peduncle up to 20 mm long; female spikes 1–8, 5–17 × 3–8 mm, shortly cylindrical to subglobose, usually clustered beneath the male spike, very rarely the lower one distant or even subbasal, sessile or shortly pedunculate, erect. Male glumes lanceolate or narrowly ovate, acute, obtuse or acuminate, light or dark reddish-brown; female glumes ± ovate, acute or obtuse, reddish-brown or light reddish-brown, 3-nerved. Utricles (1.8)2.2–3 × 0.8–1.6 mm, the lower ones spreading or slightly reflexed, those of the upper half spreading to erecto-patent and the apical ones often erect, subglobose, obovate in outline, multi-nerved, abruptly narrowed into a beak 0.3–0.8(1.3) mm long, straight, bidentate, smooth.
