Taxonomic CommentsSpecies of southwestern California and adjacent Baja California, Mexico. Two varieties (vars. pauxillus and purpureus) are considered by Kartesz (1999) to be endemic to California, but varieties are not recognized by the Flora of North America (vol. 17 2019), Munz or Jepson; unclear whether the Mexican reports represent a third variety. The Flora of North America transfers Mimulus purpureus to Erythranthe purpurea; these represent the same concept for the element.
