Panarctic Flora


342106 Agrostis canina L.


Northern Fennoscandia: Rare
Kanin - Pechora: Persistent (Adventive)
Shrub Tundra: Rare
Bordering boreal or alpine areas: Frequent

2n= 14 16 (2x). - Europe, Russia. - Numerous reports.
Not included: Only the diploid number is found in material reliably identified as A. canina s. str. (Björkman 1960; Widén 1971). Numerous reports of 2n = 28, 35, 42, and of intermediate numbers reported under the name A. canina (e.g., Björkman 1951, 1954a, 1954b) probably belong to other taxa and hybrids.

Geography: European: NOR RUS.

Notes: Sekretareva (1999) considered Agrostis canina adventive in arctic and near-arctic parts of European Russia (the Murman area and Kanin-Pechora). This is contrary to its ecology (mainly poor minerotrophic fens) on the Norwegian side of the border and suggests that the name is assigned to different plants on the two sides of the border. Note that the morphologically similar but more often adventive A. vinealis (earlier included in A. canina) is not reported from arctic Russia but is reported to be frequent just across the border in Norway.

Harvey (2007) mapped A. canina (s. str.) from three places in eastern, southern, and southwestern Greenland. We do not know the background of these reports. Böcher et al. (1978) did not accept the species from Greenland.
