Translation Stems up to 200(300) cm tall, green. Inflorescence with (5)27–49(60) spikelets arranged in an anthela (2.5)3.5–8.5(15) cm long; less frequently, all spikelets arranged in a ± lax glomerule or in a sessile fascicle. Spikelets (9)11–18(23) mm long, with (12)18–36(40) flowers. Glumes 2.5–3.4(4.5) × (1.8)2–2.8(3) mm, with a notch of (0.2)0.3–0.6(0.9) mm and a mucro of (0.2)0.4–0.8(1.1) mm; smooth, sometimes with a few spinules or brownish-reddish papillae toward the apex, especially on the lower glumes of each spikelet; margin glabrous or slightly hairy, often very hairy when spikelets are young; light to dark reddish-brown in color, more or less uniformly colored, sometimes finely punctate, very rarely hyaline. Stigmas 3, more rarely some flowers with 2. Achenes (1.7)2–2.8(3) × (1.3)1.5–2.2 mm, mostly obtusely trigonous; perianth bristles 4–6(7), shorter than or equal to the achene, more rarely slightly longer, often 2 or 3 of them shorter than the others. 2n = 42.
