Pistillate scales reddish brown or gold, with pale gold midstripe, lanceolate, 4.5–5.8 mm, 3/4 length of and narrower than perigynia, margin white, 0–0.15 mm wide, apex acute. Staminate scales with white-hyaline margin 0–0.2 mm wide. Perigynia appressed to appressed-ascending, green to gold, conspicuously 8–14-veined abaxially, conspicuously 4–8-veined adaxially, at least 3 adaxial veins longer than achene, lanceolate to ovate, plano-convex, 5.9–8.5 × 1.5–2.2 mm, (0.5–)0.6–0.7 mm thick, margin flat, including wing 0.3–0.5(–0.6) mm wide, ciliate-serrulate at least distally; beak red-brown or brown, often white-hyaline at tip, usually cylindric, unwinged, ± entire for 0.5–0.8 mm, occasionally flat, ± ciliate-serrulate, abaxial suture inconspicuous, distance from beak tip to achene (2.6–)3–4.1 mm.
