Löve and Löve (1975a) considered Elytrigia repens uniformly hexaploid but the reports above rather indicate a wide span and at least two main ploidy levels. For some reason (probably an editing error), Barkworth et al. (2007) reported this species with 2n = 22 and 42.

Notes: We assume that Elytrigia repens is adventive in the Arctic but it may be archaeophytic on seashores in northern Norway and in the Murman area, perhaps also farther east. In Greenland, it remains vegetatively but does not reproduce by seeds. Other subspecies, partly littoral, are found in Europe and western Asia.
