Notes: Three races have been described: the North American subsp. asarifolia, the either Asian (Haber and Takahashi 1988; Freeman 2009a) or more widely and northernly distributed (e.g., Hultén 1968a) subsp. incarnata, and the Pacific American subsp. bracteata (Hooker) Haber. Hultén (1968a and elsewhere) recognized a mainly temperate to boreal North American var. asarifolia and a more northern var. purpurata (same as P. incarnata) in northern Asia and North America, in America strongly overlapping with var. asarifolia. Haber and Takahashi (1988), followed by Freeman (2009a), considered all American plants as subsp. asarifolia (and subsp. bracteata), all Asian plants as subsp. incarnata. Haber (1983) synonymized subsp. incarnata with subsp. asarifolia.
Löve and Löve (1975a) reported P. rotundifolia subsp. incarnata to reach the Arctic in (northeastern) Europe and the Russian Far East, whereas they reported P. rotundifolia subsp. asarifolia to reach it in Siberia, the Russian Far East, and northwestern North America. This distinction is contrary to North American treatments (see above). Malyschev (1997) entered P. asarifolia for Siberia.
Freeman (2009a) cited P. asarifolia var. purpurea (Bunge) Fernald as a synonym of his strictly North American subsp. asarifolia. This must reflect application rather than type as Bunge's name was based on a central Asian plant (as specified by Haber 1983: 296).
