Description Culms 20–75 cm, glabrescent. Leaves: sheaths sparsely pilose, but usually densely pilose at mouth; ligules shorter than wide; blades 1.5–4 mm wide, glabrescent, or often persistently pilose proximally. Inflorescences: lateral spikes approximate or proximal distant, 6–15 × 4–5 mm; terminal spike gynecandrous, at least 1/2 of flowers pistillate, 14–25 mm. Pistillate scales ovate, 1.9–3(–3.5) × (0.8–)0.9–1.5(–1.7) mm, shorter than to equaling perigynia, apex acute to acuminate, sometimes with awn to 0.5 mm. Staminate scales oblong-obovate, 2.7–5.3 mm, apex acuminate or short-awned. Anthers 1.5–2.2 mm. Perigynia ascending, 5–18-veined, obovate-circular, ± trigonous in cross section, 2–3.5 × 1.1–2.1 mm, not papillose, glabrous or sparsely pilose; beak absent. Achenes 1.6–2.3 × 0.9–1.5 mm. [details]

Description Densamente cespitosas, sin rizomas reptantes. Tallos 20-60 cm, delgados, agudamente trígonos, lisos o escábridos en el ápice, glabros; vainas basales negro-rojizas. Hojas más cortas que los tallos, 1.5-3 mm de ancho, aplanadas, verde opaco; lígula 1-3 mm, más ancha que larga. Inflorescencia 1-2.5 cm; espigas (2-)3(-5), 6-15 x 4-7 mm, oblongo-ovoides, traslapadas, erectas, subsésiles, la terminal pistilada arriba y estaminada en la base, las laterales completamente pistiladas; bráctea más baja rebasando a la inflorescencia, foliiforme, no envainante. Glumas pistiladas c. 2/3 de la longitud de los utrículos, ovado-lanceoladas, obtusas o cortamente aristadas, pardusco pálido, frecuentemente matizadas de rojizo, la nervadura media verdosa o pálida, los márgenes angostos hialinos. Utrículos 2-2.5 mm, obovoides, obtusamente trígonos, verde-grisáceo oscuro o pardos, papilosos o diminutamente tuberculados, inconspicuamente nervados, sin rostro. Estigmas 3. [details]
