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.

Mimulus acutidens Greene is heterotypic with the South American M. acutidens Reiche, which is a later homonym. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
