Discussion | Erythranthe caespitosa is endemic to northwestern and central Washington (Cascade and Olympic mountains) and adjacent British Columbia (Cascades, Selkirk Mountains and Chilliwack Valley, Coast Mountains). The plants have consistently small leaves with subentire margins, and the stems are consistently procumbent to decumbent-ascending, usually forming matted colonies. Erythranthe caespitosa and E. tilingii appear to be sympatric in counties of northwestern Washington, but this needs to be verified in the field.

Erythranthe dentata is distinctive and rarely misidentified. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
