Description Culms (10)20–40 cm × 1–2 mm, yellow-brownish. Basal sheaths orangey-brownish. Leaves 25–45 cm × 3.0–4.7 mm largest ones, longer than the culms, old-est ones orangey-brownish at the base. Inflorescence racemose, 4.8–8.6 cm long, with 6–15(25) androgynous spikes, spreading or dropping. Proximal-most bract 6.0–9.3(18.1) cm × 1–3 mm. Spikes (1.8)2.4–3.9 cm × 3.1–5.9 mm, linear to oblong, densely flowered, the distal tip staminate, unbranched, with about 100–180 female flowers, peduncles smooth, usually the lowest shorter than the spikes and the up-per ones longer than them. Pistillate glumes 3.6–4.4 × 1.1–1.4(1.8) mm, elliptic to lanceolate, obtuse, muticuous, purplish-black with a light-green middle longitudi-nal strip, hyaline margins extremely narrow or absent, when present it is wider on the proximal half of the glume. Stigmas 2. Utricles 2.2–3.6 × 1.6–1.9 mm, orbicular, smooth, greenish, nerveless, constricted at the apex into a 0.3–0.4 mm long straight beak, smooth, truncate. Nutlets 1.4–2.4 × 0.7–1.6 mm, elliptic. [details]
