Leaves shorter or longer than the culm, linear, 4–8 mm wide, flat, soft herbaceous. Upper bracts spathe-like, upper part glumaceous to rarely with short lanceolate leaf blade 5–10 mm, sheath less than 2 mm to not exist; lower bracts have longer leaf blade, 1–4 cm, and longer sheaths 2–4 mm. Spikes (2–)3–4, terminal spike staminate, lanceolate-oblong, 5–8 mm, peduncle short, < 2 mm to sessile, very close to the adjacent pistillate spike; lateral spikes all pistillate, oblong to elliptic, 8–10 cm, spikelets very few, 2–3(–4), densely clustered; peduncles of upper spikes short to almost absent, lower spikes with slender and rather flaccid peduncles up to 3 cm long-exserted beyond the bract sheath. Male glumes oblong to elliptic, 3–4 × ca. 1.5 mm, apex broad-acute or obtuse, midrib green, margin broad hyaline. Female glumes ovate-oblong, 3.5–5 × 1.2 mm, apex acute, pale, margin broad hyaline, midrib green. Utricles longer than glumes, ovate-fusiform, trigonous, 6.5–7 mm, glabrous, brown-green, membranous, many-veined, base cuneate, upper part attenuate to a long beak; orifice hyaline, emarginate, 2-toothed.
