Inflorescences open or dense, green to brown, 1.1–3 cm × 5.4–16.3 mm, appearing fine-textured; proximal internode (1.5–)2.5–9.5 mm; 2d internode 1–3(–6) mm; proximal bracts scalelike or bristlelike shorter than inflorescences.

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.
