|discussion=<p>Variety hesperium is present at the northeastern limit of its range in Quebec only on the clays of the southern James Bay; a report of introduction in the Gatineau area is attributable to <i>Symphyotrichum robynsianum</i>. In north-central Ontario, it is found mainly in areas of clay deposits or in calcareous stream valleys, but not in the Clay Belt, reaching the southern James Bay. This variety has been treated mostly as a distinct species in floras. Character ranges overlap considerably with <i></i>var.<i> lanceolatum</i>, and it is often difficult to distinguish the two entities where their distributions overlap. In areas of sympatry, the two taxa hybridize to form septaploid plants (2n = 56).</p>
