    Plants densely cespitose.
    Leaves: sheath adaxially white-hyaline, summits U-shaped to rounded, often prolonged to 6 mm beyond collar;
    distal ligules 0.8–2.5 (–4) mm;
    blades (2–) 3–4 per fertile culm, 6–30 cm × 1.7–3.6 mm.
    Inflorescences dense or open, green and brown, gold, or brown, 1.4–3 cm × (5–) 8–15 mm, stiff, appearing coarse-textured;
    proximal internode 3–7 mm;
    2d internode 1–4 mm;
    proximal bracts usually aristate, shorter than inflorescences.

    Pistillate scales white, gold, redbrown, or chestnut-brown, usually with pale to green midstripe, ovate to broadly ovate, 2.8–3.7 mm, shorter or longer and narrower than perigynia, margin occasionally white, 0.1–0.2 (–0.5) mm wide, apex usually acute to acuminate.
