Achnatherum is a genus of plants which includes several species of needlegrass.1] Several needlegrass species have been switched between Achnatherum and genus Stipa; taxonomy between the two closely related genera is still uncertain.
Achnatherum hymenoides was useful as a food source to Native Americans. is best known as a noxious weed.
