Discussion

Erythranthe bicolor ranges from Shasta and Trinity counties south to Tulare County; the identity of apparently disjunct populations in San Bernardino County needs to be reexamined.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Erythranthe inconspicua occurs in Sierran counties from Kern north to El Dorado and then is apparently disjunct further northward to Butte County. A record from Los Angeles County (Bigelow s.n., 14 May 1854, the type of the species) is probably mislabeled, as other collections by Bigelow on the same day are from Calaveras County.
