2n= 104 72-106 (6x-8x).

Geography: North American (NE) - amphi-Atlantic: NOR RUS CAN GRL.

Notes: Hultén (1943a) mapped Stellaria crassipes as amphi-Atlantic from Ellesmere Island in northeastern Canada across Greenland and Svalbard east to Novaya Zemlya and Polar Ural, including the small, isolated, non-arctic populations in northern Scandinavia and southern Norway. Many Russian and some North American authors have accepted this species from other arctic regions, i.e., as fully sympatric with several other taxa. Petrovsky commented that it occurs in the Russian Far East, at least as common on Wrangel Island. However, Pavlova and Bezdeleva (1996) did not accept S. crassipes from the Russian Far East and neither did Vlasova (1993) from Siberia. We follow Hultén's proposal.

Material from the type region has been counted as octoploid (2n = 104) as all other material of this group from northern Europe.
