Discussion | Varieties 4 (4 in the flora). G.Boraiah and M.Heimburger (1964) conducted an extensive cytotaxonomic analysis of this wide-ranging and extremely variable species and its relatives. The present treatment takes a broader view of the species (and its variation) and recognizes fewer entities. In addition, Anemone tetonensis and A. stylosa, plants treated as closely related species by G.Boraiah and M.Heimburger, are treated here as varieties of A. multifida. Early-season plants of Anemone multifida var. multifida have solitary flowers and will key to var. saxicola. Anemone multifida var. tetonensis and especially var. saxicola might be based on characteristics that are influenced primarily by environment; further study is warranted. Native Americans used Anemone multifida (no varieties specified) medicinally as an antirheumatic, cold remedy, nosebleed cure, and general panacea, as well as a means of killing lice and fleas (D. E. Moerman 1986). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
In North America, Anemone acutiloba and A. americana are sufficiently well differentiated to enable the distinction of the two species. Some intermediates do occur but it is uncertain as to whether thes intermediates or hybrids. The fact that the two species are highly sympatric and still maintain their differences implies that they should still be recognized as distinctive species (see G.L. Stebbins 1993). The two North American species formerly placed in Hepatica are closely allied to the Eurasian Anemone hepatica Linnaeus [=Hepatica nobilis Miller, Hepatica hepatica (Linnaeus) Karst]. Among European collections, plants approach either A. acutiloba or A. americana in leaf morphology, but some intermediates are found (J. A. Steyermark and C. S. Steyermark 1960). North American plants differ from A. hepatica in having narrower sepals, larger involucral bracts, and shorter and less pubescent scapes. Further research, including a comparative study of breeding systems, is needed to clarify the relationship between Anemone hepatica, A. acutiloba, and A. americana. Pending such work, the eastern North American hepaticas are here recognized as distinct species. D. E. Moerman (1986) lists Hepatica acutiloba as one of the plants used medicinally by Native Americans in the treatment of abdominal pains, poor digestion, and constipation, as a wash for "twisted mouth or crossed eyes," and as a gynecological aid.
