| Notes | Nikiforova (1990c) reported Alopecurus aequalis from all northern regions of Siberia but without map or specific records. Hultén and Fries (1986) mapped it from some arctic Siberian regions. These are included in the distributional table. Löve and Löve (1975a) accepted three subspecies from the Arctic: subsp. aequalis throughout, subsp. amurensis from the Russian Far East (mapped as non-arctic by Hultén 1962), and subsp. aristulatus from the Russian Far East, Canada, and Greenland. The majority of authors, including Soreng et al. (2003) and Crins (2007b), do not recognize subspecies within this species even if much of the Beringian, Canadian, and Greenlandic material perhaps may deviate morphologically in some small features from the majority of the Eurasian material. |
