2n=
56-118. - Europe, Russia. - Numerous reports.
Löve and Löve (1975a) referred numerous counts from non-arctic areas in the range 52-100 but their assignments of reports to this species are unreliable. Jalas and Suominen (1994) referred numerous more recent counts in the range 56-118.
Not included: Löve and Löve (1975a) referred under this taxon a report of 2n = 80-100 from northern Alaska (Packer and McPherson 1974, by the authors for C. pratensis), and Löve and Löve (1982a) reported 2n = 80 for C. dentata from Churchill at Hudson Bay, Manitoba, Canada. This species is not accepted from North America and the counts belong to C. polemonioides.
Geography: European - Asian: RUS?
Notes: Cardamine dentata has been mapped as frequent in the Arctic in European Russia (Lashchenkova 1976b; Jalas and Suominen 1994, probably mainly based on Lashchenkova) and to be the most common species of the group in the Arctic in Siberia (Doronkin 1994). This may be due to a Russian assumption that subsp. angustifolia is American only. Arctic occurrences of C. dentata are not impossible but perhaps improbable. In northwestern Europe, C. dentata reaches the northern boreal zone but becomes very rare in the northernmost parts and does not reach the arctic treeline. All material we have seen from the Arctic in Europe, Siberia, Chukotka, or North America belongs to C. polemonioides.
