Discussion | Ranunculus repens is widely naturalized in many parts of the world. Plants with sparse pubescence have been called R. repens var. glabratus. Horticultural forms with the outer stamens transformed into numerous extra petals occasionally become established and have been called R. repens var. pleniflorus. These variants have no taxonomic significance. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The Navaho-Ramah considered Ranunculus inamoenus to be an effective hunting medicine, used to protect hunters from their prey (D. E. Moerman 1986). Varieties 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
