Inflorescences: peduncles proximal pistillate spikes to 11 cm, distal spike sessile; staminate spike 0.5–10.6 cm. Bracts 0.5–11.2 cm × 0.5–4 mm, angles of bract sheath denticulate; bract blade of distal lateral spikes linear, narrower than spikes, not concealing them; widest bract blade of distalmost lateral spike 0.5–3.4 mm wide. Spikes (3–) 4 (–5) per culm; lateral spikes 5–27 × 3–4 mm; internode between proximal scales in proximal spike 1.1–3.2 (–4.8) mm; terminal spike linear, 11–21 × 1–2.2 mm. Pistillate scales 2.8–3 × 1–1.2 mm, apex acute to aristate, awn to 1 mm. Staminate scales 3.5–4 × 1.2–1.5 mm, margins hyaline, purple-brown or brownish purple-tinged, apex acute. Anthers 2.6–3 mm. Perigynia 4–12 per spike, closely overlapping, aggregated, ascending, conspicuously (22–) 25–32-veined, elliptic-obovate, 2.8–3 × 1.5–1.8 mm, 1.8–2.7 times long as wide; beak abruptly bent, 0.2–0.8 mm.
