This species is native to Canada and the United States, where it is widespread. However, it is absent from most of the Southeastern United States.[3] It is found in a diversity of freshwater aquatic habitats, often in streams with slow moving water.[4]
There has been some difficulty in separating this species from the closely related Ranunculus trichophyllus, due in part to the lack of preservation of critical features on herbarium specimens.[5]
