Morphology and biology.

Perennial grass. Numerous culms 20-110 cm tall, less often few, with few cauline leaves. Rhizomes short, with thin rather short subterranean shoots. Leaves convolute setosely, 3-14 cm long, (0.5)1.5-4 mm wide. Radical leaves convolute, 0.5-1.5 mm diameter, greyish-green, long and thin-sharpened, subglabrous on both surfaces, less often weakly scabrous on lower (outer) surface. Ligule short, up to 2 mm long. Panicles 5-20 cm long, before and after flowering condensed or slightly lax, up to 5 cm wide, their branches directed obliquely upward and thin, more or less acutely scabrous almost entirely, rarely subglabrous in lower part. Spikelets 1.5-2.2(2.5) mm long, violet, fulvous-violet or pale green. Glumes about 2 mm long, equal or subequal, lower ones usually slightly longer than upper, acutely scabrous along most of keel, and covered with dense short spinules near apex. Lemma slightly shorter than glumes, 1.25-2 mm long, with more or less geniculate awn rising from the lower third of the lemma back, less often awnless; palea rudimentary. Anthers 0.8-1.3 mm long. Flowers in May - June. Anemophilous. 2n=14, 28.
