- Brouillet & S. Selliah, Sida 21: 1635 (2005). - Aster pygmaeus Lindl. in Hook., Fl. Bor.-Amer. 2: 6 (1834). Described from "Bloody Falls at Coppermine River", Nunavut (Canada). - Aster sibiricus var. pygmaeus (Lindl.) Cody, Canad. Field-Naturalist 68: 117 (1954). - Aster sibiricus subsp. pygmaeus (Lindl.)

Geography: American Beringian: ALA CAN.
Notes: Elven and Murray: As seen from the synonymy above, this species has vacillated between Symphyotrichum and Eurybia in recent times. Phytogeographically, Symphyotrichum pygmaeum falls into an assumedly relictual pattern shared by several other taxa in coastal northwestern Canada and northeastern Alaska. Such disjunct ranges may have been connected by the non-glaciated, now largely submerged shelf areas of northeastern Beringia.
