Russia Flora: Plant 50—200 (250) cm tall, with scaly rhizomes, not forming tufts. Stems erect, glabrous and smooth. Sheaths usually glabrous (but in young shoots often long-hairy); leaf blades 7—18 mm wide, flat, long-acuminate, rather rigid, with whitish thickened midrib, glabrous (only with long hairs at base); ligule of upper leaves about 1 mm long, ciliate. Inflorescence 13—26 (35) cm long, of 8—25 (30) spike-like branches, fan-like expanding upward, densely hairy at lower nodes. Spikelets 4.2—5 mm long, falling entire at fruiting, on pedicels, with upper fertile and lower sterile flower. Glumes thinly leathery, with membranous margin, covered with long silky hairs (up to 10 mm long at spikelet base). Lower lemma of fertile flower ciliate along margin, at apex with very thin point up to 1.5 mm long. Anthers 2—2.7 mm long. 2n=40 (Probatova, Sokolovskaya, 1983a).
