Discussion | Erythranthe nudata is distinct in its annual duration, few, inconspicuous, and narrow leaves, long and spreading-divaricate pedicels, and large corollas. The plants apparently are restricted to serpentine substrate and known only from Colusa, Glenn, Lake, Mendocino, Napa, and Sonoma counties.

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