    Leaves: sheaths adaxially white-hyaline, summits concave or truncate, prolonged beyond collar to 2.5 mm, papillose at least near apex;
    distal ligules 1–5 mm;
    blades 3–4 per fertile culm, 2.5–25 cm × 2–5 mm, usually adaxially papillose.
    Inflorescences open, pale-brown, 0.24–0.62 cm × 8–15 mm;
    proximal internode 5–17 mm;

    Spikes 3–6 (–8), distant, distinct, ovoid to clavate, 7–21 × 5.5–12 mm, base rounded to long tapered, apex rounded.
    Pistillate scales reddish-brown with green midstripe, lanceovate to ovate, 3.1–5.4 mm, 1.9–3.2 times as long as wide, (1–) 1.4–2.3 mm shorter than perigynia, narrower than perignyia, apex obtuse to acute.
    Anthers (2.4–) 2.8–4.2 mm.
    Staminate scales obtuse.
    Perigynia 15–80 in larger spikes, ascending or ascending-spreading, green to pale whitish green with reddish-brown margin, conspicuously 8–12-veined abaxially, 4–8-veined adaxially, broadly elliptic to nearly orbiculate, (4.5–) 5.1–6.7 (–7.1) × (2.4–) 2.8–4.2 mm, 0.5–0.7 mm thick, membranaceous with brown achene visible through hyaline adaxial face, margin flat, including wing 0.8–1.2 mm wide, often erose, scalloped, or with an irregular tooth, smooth;
