Description Plants without conspicuous rhizomes. Culms 10–30 cm, 0.5–1 mm wide basally, 0.4–0.5 mm wide distally. Leaves: sheaths tight, green, fronts hyaline; ligules less than 2 mm, wider than long; widest leaf blades 1–1.7 mm wide. Inflorescences with 3–8 spikes, 0.6–3 cm × 5–6 mm; proximal internodes 1–2 times as long as proximal spikes; proximal bracts to 1(–3) cm; spikes with 3–10 spreading or reflexed perigynia. Pistillate scales hyaline or pale brown with green midvein, ovate, 1.8–2.4 × 0.8–1.3 mm, body 2/3 to almost length of perigynia, apex acute, acuminate or short-awned. Anthers 1 mm.
