Discussion
L. D. Benson (1948) reported Ranunculus flammula var. flammula only from eastern Canada and referred all material from the Pacific Slope to Ranunculus flammula var. ovalis. Benson's treatment is not tenable, however, because some western collections are indistinguishable from the eastern plants.
