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.

Erythranthe inamoena is distinctive in its completely glabrous herbage, small corollas, flowers in racemes mostly at distal nodes and with reduced bracts, short and open-throated fruiting calyces, erect and fistulose stems, and apparent annual duration (fibrous-rooted but usually rooting at proximal cauline nodes).

Presumably because of its autogamous reproduction, Erythranthe inamoena has been confused with E. cordata, especially in the trans-Pecos region of Texas, where the two are sympatric. In contrast to E. cordata, E. inamoena usually has glabrous pedicels and calyces, flowers often produced from all nodes, smaller calyces [(7–)8–11 mm] that do not close at maturity, and corollas with a shorter tube-throat (7–11 mm).

Some populations in Brewster, Presidio, and Val Verde counties are identified here as Erythranthe inamoena (based on proximal-to-distal distribution of flowers and the short mature calyces with open throat) but have sparsely stipitate-glandular pedicels and calyces.
