Erythranthe moschata

Erythranthe michiganensis
Phenology Flowering May–Aug. Flowering Jun–Aug(–Oct).

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.

Based on data from allozyme and RAPD studies, morphology, and crossing studies, A. L. Posto and L. A. Prather (2003) raised Erythranthe [Mimulus] michiganensis to specific rank. The species is endemic to a small area in the Mackinac Straits and Grand Traverse regions of Michigan; it is known to be extant at 15 sites and apparently is extinct at three previously known sites. Plants of all but one of the populations are essentially pollen-sterile and reproduce through rhizomes. However, the didynamous stamens and stigma positioned above the adaxial anther pair, along with the relatively large corollas with broadly expanded limb, are reflective of an allogamous breeding system, which seems unusual in view of its apparent sterility. The narrow geographic distribution of E. michiganensis lies within the wider range of E. geyeri, and the two are known to co-occur at two sites, apparently without hybridization or morphologically intermediate individuals.

Erythranthe michiganensis (as Mimulus michiganensis) is in the Center for Plant Conservation’s National Collection of Endangered Plants.
