Notes:
This species was recently ranked by the BC Conservation Data Centre as SX (extirpated) since it has not been collected in over 50 years (Douglas 1998). Collections by Hardy from Keremeos (cited by Scoggan [1979]) and Parris from Spences Bridge (cited by Douglas [1995]) have been reidentified as Ericameria nauseosus.
