Plants without conspicuous rhizomes. Culms 17–75(–90) cm, 2–3.5 mm wide basally, 0.5 mm wide distally. Leaves: sheaths tight, green, fronts hyaline; ligules to 2.5 mm, as long as wide; widest leaf blades 2.2–4.6 mm wide, papillose adaxially. Inflorescences with 5–14 spikes, 1.4–2.8 cm × 9–14.5 mm; proximal bracts 0.7–6(–10) cm, shorter than to 2.5(–5) times as long as inflorescences; spikes with (2–)4–24 ascending to spreading perigynia; proximal internodes shorter than proximal spikes.
