|discussion=<p><i>Bromus commutatus</i> grows in fields, waste places, and road verges. It is native to Europe and the Baltic region; in the Flora region, it is found mainly in the United States and southern Canada. Hildemar Scholz (pers. comm.) recognizes three subspecies of <i>B. commutatus</i> in Europe; no attempt has been made to determine which subspecies are present in the Flora region.</p>
