Morphology and biology.

Annual herbaceous plant, 15-30 cm high, with numerous erect stems in most cases. Leaves are linear, flat. Blades, ligules and the upper part of sheaths are ciliate. Ears are short, 2-3.5 cm in length (not counting awns), with 2-3 fully developed spikelets, narrow-lanceolate; under fruits, they break at the base and fall off entirely. At the bottom of the ear there is 1 rudimentary spikelet. Spikelet glumes are oblong, ovate or obovate, almost twice as short as the adjacent lemmata, cartilaginous-leathery, with 7-13 protruding veins, without an expressed keel, scabrous or shortly pilose, topped with 2-3 awns broadened in a ribbon-like manner at the base and slightly deviated from the ear axis. Ribs of the ear axis always have large prickles. Kernels never accrete to paleae. Wind- and self-pollinated plant. Autochore. Propagated by seed. Blossoms in May; bears fruit in June. 2n=28.
