Varieties 2 (2 in the flora). Anemone drummondii is an extremely variable species whose circumscription is controversial. Some plants appear intermediate between this species and A. multifida; cytologically the two are quite distinct (G.Boraiah and M.Heimburger 1964; C. L. Hitchcock et al. 1955-1969, vol.2).
