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 hardhamiae is endemic to the central coast region in Monterey and San Luis Obispo counties. The species was previously included in E. palmeri but can be distinguished by having a wider limb (16–25 mm) than E. palmeri (8–15 mm) and pale pink flowers with a broad yellow palate and orifice. In contrast, E. palmeri has deep pink flowers with two yellow ridges on the palate.
