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 trinitiensis is similar to E. pulsiferae in its narrow leaves, glandular-puberulent vestiture, and weakly bilabiate corollas; it differs in its early-shed basal leaves, cauline leaves with one-veined petioles, and yellow corolla tubes and throats with pink lobes or lobe margins. The species is known only in Humboldt, Siskiyou, and Trinity counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
