Shrub Tundra: Rare
Bordering boreal or alpine areas: Frequent

2n= (1) 32 (4x). - Canada. - Scott (1974a), see below.
(2) 64 (8x). - Canada. - Mulligan and Porsild (1969b); Göpfert (1974); Löve and Löve (1982a, for "eremogenes").
The many Scott (1974a) chromosome counts of 2n = 32 from western and northwestern Canada (for Ranunculus sceleratus) demonstrate the absence of the constant difference in ploidy levels reported between North American and Eurasian plants by Löve and Löve (1975a). In this region, according to the map of Hultén and Fries (1986), the plants should be named subsp. multifidus and not subsp. sceleratus.

Geography: North American (NW): ALA CAN.
