Discussion | 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.) |
Erythranthe percaulis was described from only the type collection from Serpentine Canyon of the Feather River in Plumas County, but the type locality has recently been relocated and the population determined to comprise many thousands of individuals (S. Schoenig 2016). Plants are characterized by their completely glabrous vestiture, terete and mostly simple stems, small leaves on relatively widely spaced nodes, small calyces, and small, yellow corollas with herkogamous arrangement of stigma and anthers.
