Deschampsia cespitosa; the Tufted Hair-grass is one of the larger grass species on Iceland. It produces heavy tufts with course furrowed leaves. The maximal lengths of the inflorescence stems is 1m20cm. It grows wherever soil conditions are rich in nutrients, like manured grasslands and around homesteads. It can be found in many regions of Iceland except for the desert regions around and north of the Vatnajökull and the higher altitudes of the north-west. As with other "plume" grasses one can be confused by the fact that the inflorescences appear quite different in the early stages than the later stages because the panicles at first haven't spread yet.
.It is a member of the grass family Poaceae also referred to as the Gramineae family.
