Pistillate scales usually white-hyaline or hyaline gold, occasionally chestnut to dark-brown, with pale to green midstripe, ovate to broad-ovate, 2.1–3.5 (–3.9) mm, shorter than or ± covering perigynia, margin white, 0–0.2 mm wide, apex obtuse to acuminate. Perigynia ascending to spreading, green, straw colored to light-brown, or whitish, conspicuously (0–) 2–8 (–11) -veined abaxially, conspicuously 0–6-veined adaxially, veins thick, reaching, not extending beyong top of achene, lanceovate to ovate, planoconvex, 2.4–4 (–4.3) × 0.9–1.9 mm, 0.4–0.5 (–0.6) mm thick, 2.1–2.7 times as long as wide, margin flat, including wing 0.15–0.3 (–0.45) mm wide, ciliate-serrulate at least on distal body; beak green, gold, brown or white-hyaline at tip, flat, ± ciliate-serrulate or cylindric, unwinged, ± entire for 0.4–0.7 mm, abaxial suture usually inconspicuous, distance from beak tip to achene 1.2–2 mm. Achenes elliptic to quadrate, 1–1.6 × 0.7–1.25 mm, (0.3–) 0.4–0.5 (–0.6) mm thick. 2n = 84.
