Discussion

Erythranthe pulsiferae is characterized by minutely stipitate-glandular vestiture (lacking villous hairs), elongate internodes, persistent basal leaves, small, palmately veined, cauline leaves with short, three-veined petioles and elliptic-oblong to ovate or oblanceolate blades, divergent-arcuate pedicels, and small, all yellow, weakly bilabiate corollas.

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

Erythranthe charlestonensis is characterized by its annual duration, autogamous reproduction, small stature, commonly purplish color, regularly ovate, short-petiolate leaves with shallowly crenate margins and (distal leaves) sparsely villous or glabrous adaxial surfaces, hirtellous calyces without a prominently longer adaxial lobe, and lack of glandular hairs. It is endemic to the Charleston (Spring) Mountains of Clark County, Nevada, and one locality (Union Pass) in Mohave County, Arizona.
