170 Luzula arctica Blytt

Syn.: L. nivalis auct.

This arctic species belongs to the circumpolar plants (Hultén, Circumpol. I, p. 10 and map 4). The closely related L. tundricola Gorodk. (syn.: L. arctica subsp. latifolia [Kjellm.] Pors.) has mainly an arctic-Asiatic and partly N. American distribution but occurs also in the N. Pacific area. Cf. the discussion by Porsild in Nat. Mus. Canada, Publ. Bot. 4 (Ottawa 1974), p. 15 f.
