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.
