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.

Earlier segregation of Erythranthe moniliformis as distinct from E. moschata (for example, G. L. Nesom 2012g) emphasized a primarily erect habit and tendency toward sessile to subsessile and more densely arranged cauline leaves in E. moniliformis versus a decumbent to procumbent habit and consistently petiolate leaves on longer internodes in E. moschata. Discontinuities in morphology, geography, and ecology were not confirmed in later study by Nesom (2017). Rhizomes with small, tuberlike swellings can be observed over the whole moschata/moniliformis range, and there apparently are no consistent distinctions in vestiture and corolla size. Mimulus acutidens Reiche (1911), a later homonym of M. acutidens Greene, pertains here. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
