Discussion

Erythranthe alsinoides is distinct in its short, erect stems with few nodes, small, mostly ovate to elliptic-ovate, petiolate leaves, minutely stipitate-glandular vestiture, small corollas with a prominent maroon splotch on the abaxial limb, small, non-inflated mature calyces and, most especially, by its nearly truncate calyx margin. Erythranthe pulsiferae is superficially similar to E. alsinoides but has larger calyces borne on divergent-arcuate pedicels, smaller leaf blades with attenuate to cuneate bases, and the corolla limbs are smaller and lack a prominent maroon splotch.

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.
