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 carsonensis is restricted to the Carson Valley, Eagle Valley, and Washoe Valley region of Nevada and adjacent California, with one known disjunct occurrence about 58 km to the north in Nevada. The species was previously included in the broader concept of E. montioides but can be distinguished by its much branched and compact habit, linear to spatulate leaves with clasping bases, calyx with glabrous margins, and larger corolla with one large red spot in the center. Erythranthe carsonensis has been impacted by agriculture, urbanization, and other anthropogenic changes.
