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 shevockii is known only from the southernmost Sierra Nevada in Kern County. It (as Mimulus shevockii) is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
