Description
Deschampsia cespitosa is a densely tufted perennial grass, often forming large tussocks. The culms (stems) are erect and 20-200 cm tall. The leaves can be flat or loosely inrolled and are 10-60 cm long, usually arising from the base of the plant. This species can be distinguished by its leaves, which are rough to the touch, and the narrow, sharply pointed ligule found at the junction of the leaf blade and the leaf sheath that encircles the stem
