Taxonomic CommentsFNA (vol. 24, 2007) expands the concept of Poa arctica by including P. tolmatchewii (= P. arctica ssp. caespitans) as a subspecies, while Kartesz (1994) treats it as distinct. FNA also expands the concept of Poa arctica ssp. arctica to include P. arctica ssp. williamsii and P. arctica ssp. longiculmis, while Kartesz (1994) treats them as distinct.
