Varieties ca. 12 (3 in the flora).
J. Jalas (1988), W. Greuter (1989), W. Greuter et al. (1989), J. Jalas and J. Suominen (1989), and T. G. Tutin et al. (1993+, vol. 1) have recently used the name Anemone narcissifolia Linnaeus because they considered Anemone narcissiflora an illegitimate name. B. E. Dutton et al. (1995) recently proposed to conserve the orthography of Anemone narcissiflora, and the authors of this treatment ollow 14A.1 of the Code, which recommends following "existing usage as far as possible pending the General Committee's recommendation on the proposal" (W. Greuter et al. 1994).
The taxonomy of this highly variable, widespread species is extremely controversial. The conservative approach taken here most closely approximates S.L. Welsh's (1974) treatment for the Alaskan varieties. E. Hultén's discussion (1941-1950, vol. 4, pp. 735-736) of local races and the variation within this species, however, clearly illustrates the need for a thorough biosystematic investigation. Recognition of about 12 varieties is in light of S. V. Juzepczuk's (1970) work; however, he elevated local races to specific rank in his treatment.
The Aleuts used Anemone narcissiflora (no varieties specified) medicinally as an antihemorrhagic (D. E. Moerman 1986).
