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 ampliata is known from Clearwater, Lewis, and Nez Perce counties in Idaho and six western counties in Montana. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
