|discussion=<p>The distributional data given here are highly provisional; the author has not attempted to sort this taxon accurately, if it can be. According to A. Cronquist (1947), <i></i>var.<i> septentrionalis</i> is scattered mostly in the northern half of the continent and (1994) is “found chiefly in New England and adjacent Canada.” It is “morphologically transitional” to <i>Erigeron annuus</i> (A. Cronquist 1994) and, as implied by the synonymy, may be more appropriately treated as part of <i>E. annuus</i> (D. Frey et al. 2003). As noted by Fernald in the original description, the stems may be nearly glabrous or lightly hispid, in contrast to the more densely strigose to strigillose ones of typical <i>E. strigosus</i>.</p>
