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 gemmipara is known only from Grand, Jefferson, Larimer, and Park counties in north-central Colorado. Flowers in this species are uncommon, and seed set has not been observed in natural populations; reproduction in nature appears to be solely asexual via overwintering propagules (bulbils) formed in leaf axils. Two meristems are initiated in each axil. The proximal meristem produces a pair of starch-thickened storage leaves, a rudimentary axis, and a distal pair of preformed leaf primordia that enclose the shoot apical meristem. Root primordia are present within the first node of the bulbil. The petiole of the subtending leaf expands laterally and folds adaxially to enclose the developing bulbil, and entangled trichomes along the petiole margins secure it following leaf abscission and dispersal. The leaf blades commonly are deciduous, leaving the bulbil still attached (M. R. Beardsley 1997).
