Discussion | Plants of Erythranthe tilingii are characterized by their relatively low stature and stems arising from a system of thin rhizomes and producing mostly one to three large flowers each; they usually occur at relatively high elevations. Erythranthe tilingii sometimes has been considered to include one or several infraspecific entities; from within this taxonomic amalgam, four distinct species are recognized here: E. caespitosa, E. corallina, E. minor, and E. tilingii. Erythranthe corallina and E. minor probably are more closely related to E. guttata. The populations identified here as E. tilingii from northeastern Oregon northeast to Alberta and southeast to Utah may prove to be a separate (undescribed) species. Erythranthe tilingii in the strict sense is relatively widespread over the western United States and is sympatric with E. caespitosa and E. corallina. Leaves in E. tilingii are variable in size, and particularly in Idaho, they may approach the small size of those of E. caespitosa, but the leaf margins of E. tilingii are distinctly toothed, and the stems are taller and more erect. Across the range of the species, plants sometimes produce very large leaves, but these often occur on plants with characteristically smaller leaves. This wide variability in size apparently does not occur in E. caespitosa. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erythranthe palmeri has been confused with other closely related species, including E. diffusa, E. discolor (pink form), E. rhodopetra, and E. sierrae. It was previously thought to be a widely distributed species because of this taxonomic confusion but now is regarded as endemic to the Transverse Range in the San Bernardino and San Gabriel mountains.
