Discussion | Various Navaho groups used Ranunculus cymbalaria as a venereal aid, an emetic, and a ceremonial medicine. The Kawaiisu used it as a dermatological aid (D. E. Moerman 1986). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. C. L. Hitchcock et al. (1955-1969, vol. 2) considered the name Ranunculus triternatus A. Gray to be an illegitemate homonym and used the illegitimate (superfluous) name R. reconditus A. Nelson & J. F. Macbride for this species. The name Ranunculus triternatus Poiret was not validly published (not accepted by Poiret) and does not invalidate R. triternatus A. Gray.
