Discussion | Erythranthe decora is distinct in its uniformly ovate to ovate-lanceolate leaf blades with truncate bases and regularly toothed margins, relatively long internodes, rhizomatous habit, mostly unbranched stems, often with leafy runners from basal nodes, large corollas, hairy styles, and minutely hirtellous stems, pedicels, calyces, and leaf surfaces. The densely produced rhizomes suggest a relationship with the E. tilingii group. A population in Clearwater County, Idaho, appears to be long-disjunct from the main range of the species in northwestern Oregon and the western half of Washington.

Erythranthe montioides has been previously treated as a highly polymorphic species with a relatively broad geographic range but is now recognized as narrowly endemic to Fresno and north-central Tulare counties. The following species were segregated from E. montioides: E. barbata, E. calcicola, E. carsonensis, and E. discolor. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
