Discussion | Flowers in Erythranthe primuloides and E. linearifolia characteristically appear to be scapose, but the scapes are pedicels arising from axils of greatly foreshortened stems. Occasionally in both species the internodes may lengthen somewhat, and the leaves are not so densely clustered at the base of the stems. In northern Klamath, western Deschutes, and eastern Douglas counties, Oregon, an area within the range of typical populations, Erythranthe primuloides has distinctively large corollas (limbs 10–15 mm wide). Apparent clones of large-flowered and smaller-flowered plants sometimes grow in close proximity or even intermixed, appearing as two different entities.

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).
