Discussion

Erythranthe pulsiferae is characterized by minutely stipitate-glandular vestiture (lacking villous hairs), elongate internodes, persistent basal leaves, small, palmately veined, cauline leaves with short, three-veined petioles and elliptic-oblong to ovate or oblanceolate blades, divergent-arcuate pedicels, and small, all yellow, weakly bilabiate corollas.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

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.
