Description Plants without conspicuous rhizomes. Culms 30–120 cm, 2.5–4 mm wide basally, 0.7–1 mm wide distally. Leaves: proximal sheaths loose, longitudinally green-and-white-striped and green-and-white-mottled on back, with prominent transverse veins, fronts hyaline, transversely rugose; ligules 3–7 mm, slightly longer than wide; widest leaf blades (4–)5–8 mm wide. Inflorescences with 5–10 spikes, 1.5–4 cm × 8–10 mm; proximal internodes usually not more than 10 mm, 0.7–1.5(–2) times as long as proximal spikes; proximal bracts to 2 cm; spikes with 6–20 ascending to spreading perigynia. Pistillate scales hyaline or pale brown with green midvein, ovate-circular, 1.5–2 × 1.1–1.5 mm, 1/2 length of perigynia, apex subobtuse to acute. Anthers 0.7–1.3 mm. Perigynia green, with narrow wing not more than 0.1 mm wide distally, weakly 4–7-veined abaxially, 3–4.5 × 1.5–2.5 mm, margins serrulate distally; beak 1–1.3 mm, apical teeth 0.2–0.5 mm. Achenes suborbiculate, 1.6–2 × 1.3–1.7 mm. 2n = 50. [details]
