Discussion | Erythranthe bicolor ranges from Shasta and Trinity counties south to Tulare County; the identity of apparently disjunct populations in San Bernardino County needs to be reexamined. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
