Description Culms 8–50(85) cm × 1–2 mm. Basal sheaths orangey-brownish to purplish-black. Leaves 13–65(102) cm × 2.5–7.1(8.4) mm largest ones, usually shorter than the culms, but sometimes subequal or slightly longer, oldest ones orangey-brownish at the base. Inflorescence racemose with few spikes to paniculated, sometimes bear-ing smaller spikes in the base, 4.0–14.2 cm long, with 3–30 androgynous spikes, spreading or dropping. Proximal-most bract 3.5–18.5 cm × 2–6 mm, usually sube-qual to the inflorescence, but sometimes much longer or shorter. Spikes 1.3–3.6(4.5) cm × 3.5–9.5 mm, ovate to oblong, densely flowered, the distal 1/5 to 1/4 staminate, 1–2-branched, with about 15–90 female flowers, peduncles smooth, rarely sparsely scabrous, mostly shorter but sometimes subequal to the spikes. Pis-tillate glumes 3.0–5.7(7.6) × 0.9–1.9 mm, ovate to lanceolate, acute, muticuous, purplish-black with a light-yellow middle longitudinal strip, hyaline margins ex-tremely narrow or absent, when present it is only on the terminal half of the glume. Stigmas 2. Utricles 2.3–3.8(4.9) × 0.9–1.6 mm, obovate to elliptic, smooth, yellow-ish to brown with some darker spots mainly on its upper half, nerveless or nearly so, with a basal stipe 0.3–1 mm long, constricted at the apex into a 0.3–0.8 mm long straight beak, smooth, truncate or shortly bifid, with teeth up to 0.2 mm long. Nut-lets 1.3–2.2(2.5) × 0.5–1.2 mm, oblong to elliptic; style strongly lignified, leaving a cylindrical, 0.2 mm long remnant at the apex of the nutlet. [details]
