Culms 2–4.5 cm. Leaves of flowering-stems thickened, recurved, shorter to equaling culms, to 3 cm × 1.6–3.5 mm ligules of distal cauline leaves usually obsolete. Inflorescences: proximal pistillate spikes 1–3, contiguous or slightly separate, globose or elliptic, 4–5.5 mm wide; terminal staminate spikes short or long-pedunculate, 5.1–6.1 × 1.6–2.1 mm. Perigynia dark green to yellowish green, 2.3–2.8 × 1.3–1.5 mm, apex abruptly narrowed into a scabrous or smooth, reflexed beak; beak 0.4–2.1 mm, forming an angle of 5–28° with body. Achenes 1.2–1.4 × 0.9–1 mm.
