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 chinatiensis is similar to E. parvula in its prostrate habit, five-lobed calyces, and fimbriate corolla lobes. It differs from the latter in its nearly glabrous leaves and strongly reflexed abaxial corolla lip. Erythranthe chinatiensis is known only from Presidio County but should be expected to occur also in adjacent Chihuahua, Mexico.
