Characteristics

Herbs perennial, cespitose, to 1 m; rhizomes scaly; offshoots cormose. Culms erect to leaning, smooth except in inflorescence. Leaves: all sheaths hispid-hirsute, sometimes also hirtellous; principal blades linear, 8–20 cm, abaxially puberulent, hispid-hirsute, adaxially hispid-hirsute-ciliate, scabridulous. Inflorescences in clusters of terminal spikelets or from 1–3 penultimate nodes, proximalmost involucral bract longest, exceeding inflorescence, distal 1–2 bracts shorter. Spikelets ovoid to cylindric-lanceoloid, 1–2 cm, apex acute; fertile scales 2.5–3.5 mm; cusp excurved, more than 1/2 length of scale, scabrid; ribs 3–5(–7). Flowers: perianth bristles reaching base of perianth blades or beyond, retrorsely barbellate; perianth blades narrowly to broadly ovate, uniformly compressed or distally tumid, 1 mm, base 3-ribbed, apex incurved, acuminate; anthers 3, 1 mm. Achenes: stipe shorter than perianth stipe; body angles wirelike, pale, faces deep brown to chestnut brown, faintly cross-lined, 1 mm. 2n = 46.
