361220-21 The Ranunculus arcticus aggregate R. arcticus, R. rigescens

Geography: Circumpolar-alpine.

Notes: Rebristaya and Elven: In addition to the widespread Ranunculus arcticus, two geographically much more restricted species have been described from Russia. We tentatively accept one of these (R. rigescens) in the affinity of R. arcticus but transfer the other (R. petroczenkoi) to the R. monophyllos aggregate. However, R. arcticus is polymorphic and may consist of several recognizable taxa in both Eurasia and North America.
