2n= 28 (4x). - Europe (N), Russia (N), Far East (N), Alaska, Greenland. - Numerous reports.
Not included: A report of 2n = 84 (12x), Sokolovskaya and Probatova in Tzvelev (1976). Greene (1980) was able to substantiate only tetraploid numbers in subsp. groenlandica, by him accepted as var. borealis.

Geography: Circumpolar: ICE NOR RUS SIB RFE ALA CAN GRL.

Notes: Greene (1980) stated that Arundo groenlandica was described and with type from Labrador, not from Greenland.

The range of subsp. groenlandica is incompletely known, especially in eastern North America, due to insufficient separation from subsp. neglecta. The synonymy between "groenlandica" (Labrador type) and "borealis" (northern Swedish description) is not confirmed. Both Lange (1880) and Jørgensen et al. (1958) considered them different.
