Discussion | Erythranthe taylorii is known only from the Shasta Lake region of northwestern Shasta County. Its broad, distinctly bilabiate corollas and ovate leaf blades with palmate venation are similar to those of species of the northern group of sect. Mimulosma, the "Columbia River clade" (J. B. Whittall et al. 2006) of Idaho, Montana, Oregon, Washington, and Wyoming, particularly to the Idaho endemic E. ampliata. Erythranthe taylorii is distinct from E. ampliata in its larger, papillose calyces, shorter fruiting pedicels, corollas with shorter tube-throats, and shorter capsules. Considerable corolla color variation exists in E. taylorii in the occurrence and density of red dots and lines on the throat ceiling and larger red splotches on the abaxial limb.

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.
