Rich forests, especially along streams. First collected in Lenawee Co. by R. W. Smith in 1986; perhaps this recently described species is overlooked in similar sites in southernmost Michigan.
A recently described species formerly included with E. virginicus; this appears to flower and fruit slightly earlier than E. virginicus, and has the inflorescence more exserted from the sheath. Elymus glabriflorus occurs in northern Indiana, and might be found in southwestern Michigan. It resembles E. macgregorii in the broad inflorescence with long awns, but has more densely flowered spikes, the internodes less than 5 mm long. The rare hybrids of E. virginicus and E. hystrix resemble E. macgregorii, but differ in their narrower glumes.
