Inflorescences: peduncles of terminal staminate spikes 0.5–8 mm, 0.2–0.5 length of staminate spikes; bracts to 20 cm × 1.1–2.9 mm, 1.5–4 times as long as inflorescences; inner band of sheaths concave or truncate. Spikes: proximal pistillate spikes (1–)2–5, approximate, subsessile or short-pedunculate, globose to elliptic, 8.5–19.9 × 4.1–9.8 mm; terminal staminate spikes pedunculate, 12–21 × 1.3–2.7 mm. Scales: pistillate scales yellowish green, inconspicuous among perigynia, 1.7–2.6 × 0.8–1.2 mm; staminate scales yellowish green, ovate, 2.9–4.4 × 0.8–1.6 mm, apex obtuse or acute to acuminate. Anthers 1.1–2.9 mm. Perigynia reflexed, yellowish green, 3.5–4.8 × 1.1–1.7 mm, apex gradually narrowed; beak 1.4–2.5 mm, forming an angle of 13–48° with body, smooth.
