The plant reaches a height of 40-100 cm, rarely up to 150 cm. The straw is thin, hollow inside. The nodes are bare or pubescent only in the early stages of plant life. A leaf blade of 6-16 mm wide, at first soft, pubescent, but then becomes bare and stiff. The axes of the spikes are not brittle. At the junction of spikelets of the second order with the main axis, there are no tufts of hairs. Spikelets have approximately equal length and width. In the process of ripening, the fruit (caryopsis) is densely compressed by the lower and upper flowering scales, and upon ripening it falls out.
