Subspecies wigginsii is a Klamath Mountain endemic that occurs widely along the county boundary between Del Norte and Siskiyou counties, California, and east through southeastern Josephine County, Oregon, to Mount Ashland in Jackson County (O. H. Ballantyne 1983). It intergrades with subsp. shastense in the Marble Mountains of Siskiyou County. The solid orange flowers and yellow anthers are distinctive. Genetic instability in this subspecies is frequently expressed as malformed flowers with shrunken or missing reproductive structures.
