Discussion | Ranunculus sardous was collected in New Brunswick and Ontario in the 1800s, but it apparently has not persisted in those provinces. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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).
