Pistillate scales red-brown, red-gold, or gold, with pale brown or whitish midstripe, lanceolate to broadly ovate, 4.3-6.2 mm, shorter and narrower than perigynia, margin white, (0.1-)0.2-0.3(-0.5) mm wide, apex acute to acuminate. Perigynia appressed to ascending, green or gold, usually inconspicuously veined on each face, narrowly ovate to ovate, flat except over achene or ± plano-convex, 5.4-7.2(-7.5) × 2-2.8(-3) mm, 0.5-0.6(-0.7) mm thick, 2.4-2.7 times as long as wide, margin flat, including wing 0.45-0.8 mm wide, ciliate-serrulate at least distally; beak red-gold to red-brown, sometimes white-hyaline at tip, flat, ± ciliate-serrulate, abaxial suture usually inconspicuous, distance from beak tip to achene 2.2-3.6 mm.
