Discussion | Erythranthe washingtonensis is considered to be extirpated in Washington by the Washington Natural Heritage Program. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erythranthe gracilipes is endemic to the foothills of the central Sierra Nevada in Fresno, Madera, and Mariposa counties and apparently is most abundant after fire. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
