Inflorescences with both staminate and pistillate spikes; peduncles of basal spikes erect, short, stout; peduncles of terminal staminate spikes 2–2.5 mm; proximal nonbasal bracts leaflike, equaling or slightly exceeding inflorescences. Spikes: proximal pistillate spikes 2–6 (basal spikes 1–4); cauline spikes overlapping, with 1–4 perigynia; terminal staminate spikes 5.8–12.7 × 1.5–2.2 mm. Scales: pistillate scales reddish-brown, with similarly colored or narrow white margins, ovate, 3.6–6 × 1.2–2.2 mm, apex cuspidate to acuminate (awned on some basal spikes); staminate scales lanceolate, 3.7–5.9 × 1.4–2.2 mm, apex acute to acuminate. Anthers 2.3–3.3 mm.
