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 erubescens was long identified as E. lewisii but is distinct in its light pink corollas (versus mostly magenta-rose to purplish in E. lewisii), more broadly cylindric calyx tube [14–19 × 6–8 mm versus 12–15(–17) × 9–12 mm], and its geographic range in the Sierra Nevada of California (versus widespread from southern Alaska south to northwestern California, northern Utah, eastern Nevada, and northern Colorado in E. lewisii). The two are genetically isolated and phylogenetically distinct (see summary of evidence in G. L. Nesom 2014b).

In California, Erythranthe erubescens ranges from Modoc, Plumas, and Tehama counties south to Fresno County; in Nevada, it is known only from Washoe County and Carson City.
