Notes: Egorova et al.: Very many authors have applied the name Luzula arctica Blytt 1861 for this species (e.g., Hultén 1968a in Alaska and the Yukon Territory; Böcher et al. 1978 in Greenland; Chrtek and Krísa 1980 in Europe; Elven 1994 in Norway and Svalbard; Elven and Elvebakk 1996 in Svalbard; Cody 1996 in the Yukon Territory; Swab 2000 in North America), whereas Russian authors mostly have applied the name L. nivalis. The application of L. arctica is based on arguments by Hylander (1945, 1953b) that the earlier name L. nivalis Sprengel 1825 refers to another plant. However, Sprengel's name is explicitly based on L. campestris var. nivalis Laest., and the application must follow the type of the basionym. The lectotypes of Blytt's "arctica" (from Norway) and Laestadius' "nivalis" (from Sweden) belong to the same taxon. Kirschner's (2001b) designation of a lectotype of L. campestris var. nivalis finishes this issue.
