Discussion

Erythranthe norrisii is known only from the Kaweah River drainage; most populations are in Sequoia National Park in Tulare County. The species is characterized by its short-petiolate leaves with attenuate bases, very large corollas with red splotches at the base of each lobe and two white patches on the abaxial limb, and very short, purple-dotted calyces with rounded-thickened ribs and linear-oblong lobes incurved in fruit. The capsules often are slightly exserted.

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.
