Morphology and biology.

Perennial herbaceous plant, forming more or less dense tussocks without creeping subterranean shoots or, less frequently, with few short creeping subterranean shoots. Stems are 60-100 cm high, thick, naked. Leaf blades are very hard, on the upper side having few (often less than 10) thick and very protruding ribs covered with dispersed aciculae and setae. Sheaths of the stem leaves are cloven almost to the base, with lanceolate auricles. The ligule is 0.2-0.8(1) mm long, leathery-membranous, usually with tiniest cilia along the edge. The inflorescence is a compound spike, 5-20 cm long, non-friable. Spikelets are large, 1.4-2.5 cm long, with 5-9(11) flowers set on the rachis one by one in two longitudinal rows, sessile (pedicels are up to 0.3 mm long). Glumes are cartilaginous-leathery, obtuse, as if chopped off, 0.7-1.1 cm long, with 5-7(9) nerves, smooth. The lemma is 7-11 mm long, awnless, smooth, with five nerves. Wind- and self-pollinated plant. Autochore. Propagated by seed. Blossoms in June; bears fruit in August. 2n = 14, 56, 70.
