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 barbata previously has been placed in synonymy with E. montioides but differs from it in having each corolla lobe deeply notched and a consistently bearded palate. In E. montioides, each corolla lobe is entire or shallowly notched, and the palate is glabrous or sparsely bearded. Erythranthe barbata is most abundant in Tulare County but also occurs in immediately adjacent Inyo and Kern counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
