2n=
18 (2x, x = 9). - Far East (East Chukotka). - Zhukova and Tikhonova (1973, for subsp. dezhnevii).
Geography: Asian Pacific: RFE.
Notes: Petrovsky and Elven: Subspecies dezhnevii is known from one locality in East Chukotka and only from the type specimen and an isotype (the chromosome count voucher). This is the single known occurrence in the Arctic of this temperate Pacific species. The only difference from the more southern plants seems to be its extremely small size. Such an inconsequential difference at one locality does not deserve taxonomic recognition and thus we reduce it to synonymy.
