Discussion | Erythranthe filicaulis is known only for certain from Mariposa and Tuolumne counties. Kappler 1691 (UCLA) from Madera County also may be this species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erythranthe barbata previously has been placed in synonymy with E. montioides but differs from it in having each corolla lobe deeply notched and a consistently bearded palate. In E. montioides, each corolla lobe is entire or shallowly notched, and the palate is glabrous or sparsely bearded. Erythranthe barbata is most abundant in Tulare County but also occurs in immediately adjacent Inyo and Kern counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
