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. (Discussion copyrighted by Flora of North America; reprinted with permission.)	Erythranthe corallina is a morphologically consistent entity that occurs only in the Sierra Nevada of California and adjacent Nevada (Washoe County and Carson City). Its chromosome number is reported as 2n = 48 and 56, compared to 2n = 28 and 56 in E. tilingii; identities of the E. corallina vouchers should be rechecked and additional counts made, since the occurrence of such wide dysploidy seems unlikely. Compared to the leaf blades of E. tilingii in the strict sense, those of E. corallina are relatively broader (broadly ovate to orbicular-ovate), the plants generally taller, and long-pedicellate flowers occasionally are produced from mid stem or even proximal nodes. The hirsutulous to hirsute vestiture of eglandular hairs on both leaf surfaces is a reliably diagnostic feature and usually easily observed with a 10× lens. Some plants of Erythranthe corallina from San Bernardino County, California, produce decumbent-ascending stems (4–10 cm) and ovate-triangular leaves (blade 5–10 × 3–6 mm), but the dense system of filiform rhizomes, flowers one to three, and hirtellous foliar vestiture serve to identify them.
