Much of what has been identifed as P. hyperborea (L.) Lindl. in BC is P. aquilonis. Some material could be P. huronensis. Collections of P. hyperborea from Vancouver Island most likely are P. stricta. Further field collections are required to understand the distribution of P. aquilonis and P. huronensis in BC.
If more than one illustration is available for a species (e.g., separate illustrations were provided for two subspecies) then links to the separate images will be provided below. Note that individual subspecies or varietal illustrations are not always available.
