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 scouleri is distinctive in its oblong-elliptic leaves with long-tapering bases and closely toothed margins, completely glabrous vestiture, long, leafy runners from basal cauline nodes, large corollas with broad limbs, and prominently hairy styles. Several features suggest a close relationship to E. decora, particularly its very large corollas, hairy styles, closely toothed leaf margins, tall, simple, and erect stems, numerous runners, and its geographic range. All collections apparently have been made near the mouth of the Columbia River in Clatsop and Columbia counties, Oregon (G. L. Nesom 2013d). Recent observations (Alexander John Wright, pers. comm.; photos http://www.inaturalist.org/observations/3537008) indicate that it also occurs in Wahkiakum County, Washington, in the Julia Butler Hansen Refuge.
