Loosely tussock-forming, pale-green perennial grass with long, thin stolons. Stems arched: generative ones reach heights of 30-60 cm; vegetative ones to 10 cm. Rough leaf blades 6-15 cm long, sparsely hairy at weakly-furrowed apex. Leaf sheaths rather rough, reddish down stem. Ligule brown, truncate, up to 0.5 mm long. Panicles one-sided with 5-10 pendulous spikelets. Latter red-violet in colour up to 7 mm long. Flowers May-Jun.
Grows on mesic, moderately fertile soils, in oak-lime-hornbeam forest or oak woodland, more rarely in riparian and oak-pine forest.
