Discussion | Ranunculus bulbosus is native to Europe and the Near East but has become naturalized in many other parts of the world. It is considered an introduced weed in the flora. The Iroquois used Ranunculus bulbosus as a toothache remede and as a a treatment for venereal disease (D. E. Moerman 1986).

Of conservation concern. Ranunculus turneri was considered an arctic race of R. acris by E. Hultén (1971). It occurs from the Mackenzie Delta to northeastern Alaska. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
