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 sierrae is endemic to the southern Sierra Nevada in Fresno, Kern, and Tulare counties. The species was previously treated as E. palmeri but can be distinguished by having leaf margins that are often toothed, pale pink corollas, and white stamens. Erythranthe palmeri has entire leaf margins that are never toothed, deep pink to purple corollas, and yellow stamens. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
