Comment:
Although Shetler (1982, and pers. comm. 2012) argues that the nearctic harebells should all be considered several variable ecotype 'races' of a single species (as Campanula rotundifolia L.), Lammers (2007) restricts C. rotundifolia to the "Europe to S. Siberia, Manchuria [...], & Sakhalin" (and "naturalized in New Zealand, Tierra del Fuego & Falkland Isl."), and recognizes a number of N. American taxa separately. ITIS is following Lammers in this, and changed distributional information accordingly, pending further evaluation
