Discussion

Some plants identified here as Erythranthe floribunda in Arizona and southwestern New Mexico are distinctive in their prominently inflated calyces, sessile to subsessile leaves with attenuate bases and palmately three- to five-veined venation, and much-elongated pedicels (20–43 mm); numerous intermediates in Arizona make it difficult to conclude that the variants represent an entity discontinuous from plants of typical morphology. The variant morphology has not been observed among Mexican populations. Further discussion of this situation was given by G. L. Nesom (2012h).

Erythranthe floribunda has been documented from 12 counties in northern Arkansas (Carroll, Cleburne, Crawford, Franklin, Izard, Johnson, Logan, Newton, Pope, Searcy, Stone, and Washington), where it occurs at 300–500 m. The unpublished name Mimulus floribundus subsp. moorei Iltis appears in various checklists in reference to the Arkansas plants, but there appears to be no basis for treating them as distinct from the rest of the species. Elsewhere in the main range (western states), scattered variants extremely reduced in size, leaves, flowers, and overall stature appear to be at the lower limits of the species rather than taxonomically distinct.

Erythranthe norrisii is known only from the Kaweah River drainage; most populations are in Sequoia National Park in Tulare County. The species is characterized by its short-petiolate leaves with attenuate bases, very large corollas with red splotches at the base of each lobe and two white patches on the abaxial limb, and very short, purple-dotted calyces with rounded-thickened ribs and linear-oblong lobes incurved in fruit. The capsules often are slightly exserted.
