Discussion

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.

Erythranthe guttata is markedly variable in stature, leaf shape, vestiture, flower size, and the separation distance between anthers and stigma; it ranges from subalpine and near-alpine habitats into desert situations where water is available.

In all of Colorado, the Four Corners area, and north-central New Mexico, the vestiture of stems and calyces is consistently densely hirsute-hirtellous, without glandular hairs. Plants with similar vestiture also occur in British Columbia, Oregon, and Washington, and in scattered localities elsewhere. In northwestern Arizona, California Nevada, and southern Oregon, vestiture is consistently villous-glandular, without eglandular hairs. Elsewhere in the geographic range the vestiture is a mix of hirsute-hirtellous (eglandular) and villous-glandular hairs. Other morphological variants and patterns, as well as variation in ploidy level, within Erythranthe guttata were discussed by G. L. Nesom (2012i).

Plants of Erythranthe guttata with extremely large corollas have been frequently collected on the Aleutian Islands, Kodiak Island, and in other Alaskan localities (for example, Admiralty Island Amakuk, Juneau, and Yakutat Bay). Corolla tube-throats are 19–26 mm, and the limbs are expanded to 18–25 mm. The type collection of E. guttata is one of these plants, and the name E. guttata may prove to apply most appropriately only to Alaskan populations. Diploids and tetraploids appear to be sympatric in Alaska.

Mimulus guttatus subsp. haidensis was described as an endemic subalpine race that occurs in and along the flanks of the Queen Charlotte Mountains on Graham Island and Moresby Island. The subspecies was distinguished on the basis of its hirtellous vestiture, but plants of similar hirtellous vestiture occur over the whole range of the species. A tetraploid chromosome number (2n = 56) was reported for subsp. haidensis from a total of five localities on Graham Island and Moresby Island (J. A. Calder and R. L. Taylor 1968, vol. 2), and diploids (2n = 28) were documented from one locality on each of the two islands. At least one of the diploids has densely hirtellous stems, pedicels, and calyces, matching the morphology of subsp. haidensis.

Erythranthe guttata is naturalized in Europe and has been introduced to the northeastern United States (Connecticut, Michigan, New York, and Pennsylvania) and eastern Canada (New Brunswick).
