Notes: Elven and Tzvelev: Alopecurus borealis has mostly been referred to under the name A. alpinus Sm. 1803, described from Scotland. However, that name is invalidated by the previously described, non-arctic A. alpinus Vill. 1786 from the western Alps. Even if Smith's name "alpinus" is not available for a species, it is available for a race if the Scottish plants are regarded as such, or for a main northern race if the name "borealis" belongs elsewhere (see below). The European range is restricted to Svalbard, northeasternmost European Russia, and the isolated population in Scotland.

Tzvelev: The type specimen of A. borealis is from the area where also A. stejnegeri occurs. There might be problems with characterization of the species.
