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 cinnabarina is similar to typical E. cardinalis in its spreading anther thecae, relatively short-exserted corolla tube, and its reflexing corolla lobes but distinct in its generally larger leaves with reduced vestiture, fewer flowers, larger calyx and corolla, apically caudate calyx lobes, and its separate geographical range. Erythranthe cinnabarina occurs in Cochise County (Chiricahua Mountains), Graham County (Pinaleño Mountains), and Pima County (Santa Catalina Mountains). Erythranthe verbenacea, with which it sometimes has been confused, occurs at lower elevations (350–2600 m) and ranges over most of the state (Apache, Cochise, Coconino, Gila, Graham, La Paz, Maricopa, Mohave, Pima, Pinal, Santa Cruz, and Yavapai counties). Erythranthe cinnabarina apparently occurs alone (without E. verbenacea) in the Pinaleño Mountains and in the Chiricahua Mountains, but both species have been abundantly documented in the Santa Catalina Mountains, where they sometimes closely co-occur in areas of elevational overlap (for example, at Marshall Gulch, about 2500 m; at Bear Wallow Campground, about 2600 m).
