Discussion

Subspecies fallax is considered rare in New Brunswick, and its status in Labrador is uncertain. Narrower-leaved plants of subsp. fallax with less leafy, more pyramidal arrays can be difficult to distinguish from Solidago canadensis var. canadensis. Hybridization between the two diploid taxa is likely. Ray laminae tend to be shorter in subsp. fallax than subsp. lepida.
