Leaves ¼–1/2 length of scapes; sheaths brown to stramineous, abaxially glabrous or hirtellous; blades spreading to erect, filiform, wiry, less than 1 mm wide, involute, margins and adaxial surface glabrous to hispidulous or scabrid. Inflorescences terminal, mostly in compound, compact or diffuse, involucrate anthelae; scapes ascending to erect, wiry, 1 mm thick, coarsely ribbed, ribs glabrous or hispidulous to scabrid; proximal bladed involucral bract exceeding or exceeded by inflorescence. Spikelets red-brown to chestnut-brown, lanceoloid to cylindric, 4–6 mm, mostly longer than broad; fertile scales ovate, curvate-keeled, 2–2.5 mm, apex acute, glabrous or papillose-puberulent, midrib excurrent as mucro or mucronula. Flowers: stamens 3; anthers linear, 1–2 mm. Achenes gray to yellow-brown or dark brown, trigonous-obovoid, 1–1.2(–1.5) mm, faces rugulose, papillate; tubercle a globose button. 2n = 60.
