Discussion | Erythranthe patula is distinctive with its long-petiolate leaves with ovate blades and its small, weakly bilabiate to nearly radially symmetric corollas. Vestiture may include only minute, stipitate-glandular hairs or it may be an intergrading mix of stipitate-glandular hairs and minute (0.1–0.2 mm), sharp-pointed, eglandular hairs. Plants may have stipitate-glandular pedicels and calyces but hirtellous, eglandular stems, or they may have stipitate-glandular stems and pedicels but hirtellous calyces.

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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
