Discussion | Erythranthe laciniata is known from Amador County south to Kern County. As in Erythranthe nasuta, the adaxial calyx lobe in E. laciniata tends to be narrowly lanceolate to triangular (noselike) and perceptibly falcate, curving slightly upward both in flower and in fruit. The adaxial lobe is not so prominently protruding as it often is in E. nasuta. Corolla size is variable in Erythranthe laciniata, but the size of those with an open throat (versus much reduced in size and apparently cleistogamous) is not strongly correlated with size of the individual plant, and all on one plant are about the same size (compare with E. nasuta). Corollas on some plants, however, are all or nearly all greatly reduced and apparently cleistogamous. Fertilization in even the larger corollas apparently is autogamous; the anther pairs are slightly separated or equal in level, and the stigma is in the middle of the anthers or at the level of the adaxial pair.

Erythranthe montioides has been previously treated as a highly polymorphic species with a relatively broad geographic range but is now recognized as narrowly endemic to Fresno and north-central Tulare counties. The following species were segregated from E. montioides: E. barbata, E. calcicola, E. carsonensis, and E. discolor. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
