Discussion

The names Chrysothamnus nauseosus subsp. consimilis and var. consimilis (Ericameria nauseosa subsp. consimilis) have been used for this taxon; an equivalent combination has not been made at the varietal level in Ericameria. Variety oreophila intergrades with vars. mohavensis and speciosa.
