Inflorescences dense or open, gold to brown, occasionally beaded, 1.7–4.8 cm × 6–16(–23) mm; proximal internode 3.5–7.5 mm; 2d internode 2–5.5 mm, these 2 internodes collectively more than 1/3 as long as inflorescences; proximal bracts usually bristlelike, shorter than inflorescences. Spikes (3–)5–12, distant, loosely aggregated, ovoid to broadly ovoid, 6–14.5 × 2.5–9.2 mm, base rounded to attenuate, apex truncate, rounded, or sometimes tapered. Pistillate scales gold to brown and often reddish, with whitish or green midstripe, ovate to broadly ovate, (2.5–)3.5–4.7 mm, usually shorter than and narrower or as wide as perigynia, margin white, 0–0.2 mm wide, apex obtuse to acuminate. Perigynia ascending, green or straw colored to coppery, conspicuously 6–11-veined abaxially, (0–)4–5(–8)-veined adaxially, veins reaching top of achene, lance-ovate to ovate, plano-convex or biconvex, 3.4–4.8(–5.3) × 1.1–1.6(–2.2) mm, 0.4–0.65 mm thick, margin flat, including wing 0.15–0.4 mm wide, ciliate-serrulate at least on distal body; beak gold to brown, usually reddish, at tip, cylindric, unwinged, ± entire for 0.5–0.6 mm, abaxial suture inconspicuous or with conspicuous white margin, distance from beak tip to achene 1.5–2.5 mm. Achenes elliptic to ovate or, rarely, broadly ovate, 1.5–2 × 0.9–1.3 mm, 0.4–0.6 mm thick.
