Discussion | Erythranthe washingtonensis is considered to be extirpated in Washington by the Washington Natural Heritage Program. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
