2n= (1) 18 (2x). - Far East (N), Alaska. - At least four reports.
(2) 36 (4x). - Far East (N). - At least four reports.

Löve and Löve (1975a) considered Artemisia globularia to be uniformly tetraploid and erroneously assigned reports of other ploidy levels made under this name to other species.

Geography: Amphi-Beringian: RFE ALA CAN.

Notes: Korobkov and Yurtsev: There is a geographical pattern in the ploidy levels. Diploids occur at the Bering Strait, whereas the hexaploids are much more western and the tetraploids intermediate.
