Discussion | Erythranthe alsinoides is distinct in its short, erect stems with few nodes, small, mostly ovate to elliptic-ovate, petiolate leaves, minutely stipitate-glandular vestiture, small corollas with a prominent maroon splotch on the abaxial limb, small, non-inflated mature calyces and, most especially, by its nearly truncate calyx margin. Erythranthe pulsiferae is superficially similar to E. alsinoides but has larger calyces borne on divergent-arcuate pedicels, smaller leaf blades with attenuate to cuneate bases, and the corolla limbs are smaller and lack a prominent maroon splotch.

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.
