Elymus riparius A. A. Reznicek

Usually in moist ground along streams, borders of forests, and river banks; occasionally in somewhat drier places.

This resembles small plants of Elymus canadensis in its arching inflorescence, but occurs in moister, often forested settings, and the awns remain straight even at maturity, never becoming curled like those of E. canadensis. See also notes under E. canadensis.

The backs of the lemmas are ± hispidulous except in one specimen from Cass Co. The glumes somewhat resemble narrow ones of E. virginicus, but are ± straight, not bowed, at the base.
