Description Plants perennial, cespitose, 80–150(–170) cm, coarse; rhizomes absent. Culms stiffly erect, leafy, triangular, multiribbed. Leaves ascending, overtopped by inflorescence; blades flat proximally, 3–10(–15) mm wide, apex attenuate, trigonous. Inflorescences terminal and axillary, narrow, clusters of corymbs, clusters dense, mostly broadly turbinate, 13–15 mm; bracteal leaves mostly exceeding subtended compounds. Spikelets brown, lanceoloid, 13–15 mm, apex acuminate; fertile scales lanceolate, 10–13 mm, apex acuminate, midrib short excurrent. Flowers: longer perianth bristles usually fully 2 times length of fruit body, antrorsely barbellate. Fruits 1–2 per spikelet, 20–25 mm; body pyriform obovoid, compressed, 5–6 × 2.6–3.6 mm; tubercle attenuate, 2-grooved, (15–)18–20(–21) mm. 2n = 18. [details]
