Botanists disagree about whether Erigeron acris is limited to Eurasia, or whether there are North American populations also. The 'type' of the species is European.
In the last 20 years or so, many botanists have agreed that the species formerly called E. acris in the northern parts of North America should be either called E. acris subsp. kamtschaticus or simply E. kamtschaticus. The latter species name is what the Catalogue of Life now uses to refer to the North American Fleabanes previously called E. acris.
According to CoL, the distribution of Erigeron kamtschaticus is:
China (Gansu, Guangdong, Hebei, Heilongjiang, Henan, Jilin, Liaoning, Nei Mongol, Qinghai, Shaanxi, Shanxi); Mongolia; Russian Far East (Amur, Kamchatka, Khabarovsk, Kuril Isl., Magadan, Primorye, Sakhalin); Canada (Alberta, British Columbia, Manitoba, New Brunswick, Labrador, N.W.T., Nunavut, Ontario, Québec, Saskatchewan, Yukon); USA (Alaska, Colorado, Idaho, Maine, Michigan, Minnesota, Montana, South Dakota, Utah, Washington, Wyoming)
