Notes: Elven and Murray: Tzvelev (PAF proposal and comment) recognized the northern Alopecurus roshevitzianus apart from the more southern A. glaucus s. str. Pending further investigations, we enter the more widely circumscribed species.

Alopecurus glaucus (including A. roshevitzianus) differs in several characters from A. borealis and is without transitions towards it in the material we have inspected (northwestern North America, ALA). We accept it as species. On the American side, this species is mainly interior and alpine, and only one arctic occurrence is yet documented at Cape Prince of Wales (COLO, CAN-472963) on the Seward Peninsula, western Alaska.
