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.

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.
