Discussion | Plants from one locality in Butte County are unusual in producing filiform, small-leaved runners from basal cauline nodes. Erythranthe glaucescens is known only from Butte and Tehama counties. (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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
