Leaves: sheaths usually loose, proximally green-and-white-striped, not white spotted, with conspicuous transverse veins on back, fronts hyaline, sometimes transversely rugose and red dotted, thin, white or hyaline and fragile at mouth; ligules 2–7 mm, shorter to longer than wide; widest leaf blades (3–)4–8 mm wide. Inflorescences with 5–15 spikes, 1–5 cm × 8–15 mm, occasionally compound, then somewhat larger; proximal bracts to 3 cm; spikes with 5–15 ascending to spreading perigynia; proximal internodes shorter than to 1.5 times as long as proximal spikes. Pistillate scales hyaline or brown with green, 1–3-veined center, ovate, 2.6–4.4 × 1.3–2.4 mm, body shorter to slightly longer than perigynium, apex acuminate to short-awned. Anthers 1.5–3 mm.
