Discussion | W. J. Hooker (1829) included Anemone occidentalis in his concept of Anemone alpina Linnaeus. The Thompson Indians and the Okanagan used decoctions prepared from the roots of Anemone occidentalis to treat stomach and bowel troubles (D. E. Moerman 1986).

Anemone caroliniana was recorded from Indiana (Vigo County); it has since been extirpated. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
