Discussion

The occurrence of Erythranthe jungermannioides in the Columbia River Gorge of Klickitat County, Washington (the only record from the state of Washington), is based on an imprecise, unconfirmed observation from the early 1990s (Washington National Heritage Program 2005).

Erythranthe regni is endemic to the Kofa Mountains of Yuma County; all collections have been made from the Kofa Game Refuge (Kofa National Wildlife Refuge). Because its calyces remain open at maturity, this species is hypothesized to be most closely related to E. geyeri, from which it differs by its erect habit, apparently annual duration, larger leaves, purple-dotted calyces, and corollas with longer tube-throat and barely bilabiate limb. Geography and other morphology, however, suggest that its evolutionary origins are closer to E. guttata.
