Discussion

Erythranthe ptilota is recognized by its prostrate to decumbent or decumbent-ascending habit, large, consistently sessile leaves, densely villous vestiture, long pedicels, large calyces and corollas, hispid-hirtellous anthers, and particularly by its long, strongly unequal, linear-triangular calyx lobes usually distally falcate. Leaf bases typically are truncate to rounded or subcordate. Rarely the leaves are short-petiolate, but in such cases, the distinctive leaf bases, vestiture, calyx morphology, and pubescent anthers are diagnostic. Erythranthe ptilota is widely sympatric with E. moschata but usually occurs at lower elevations and characteristically in wetter habitats. The epithet ptilota (Greek ptilotos, winged) alludes to a fancied winglike aspect of the pairs of sessile leaves.

A population system of Erythranthe ptilota-like plants occurs in southern California, about 480 km disjunct from the main range of the species. These plants have the prostrate habit, large leaves, long pedicels, and large corollas of E. ptilota, but the calyx lobes are variable in length and usually do not show the characteristic attenuate-apiculate apices. The southern California plants are identified here as E. moschata.

Erythranthe ptilota is a new name at specific rank for Mimulus moschatus var. sessilifolius [not E. sessilifolia (Maximowicz) G. L. Nesom].

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.
