Discussion	Erythranthe decora is distinct in its uniformly ovate to ovate-lanceolate leaf blades with truncate bases and regularly toothed margins, relatively long internodes, rhizomatous habit, mostly unbranched stems, often with leafy runners from basal nodes, large corollas, hairy styles, and minutely hirtellous stems, pedicels, calyces, and leaf surfaces. The densely produced rhizomes suggest a relationship with the E. tilingii group. A population in Clearwater County, Idaho, appears to be long-disjunct from the main range of the species in northwestern Oregon and the western half of Washington. (Discussion copyrighted by Flora of North America; reprinted with permission.)	Erythranthe unimaculata is recognized by its annual duration (fibrous-rooted, without stolons or rhizomes), delicate-glandular vestiture, mostly sessile to subsessile, often widely spaced leaves, closed fruiting calyces, and relatively large, pale yellow to nearly white corollas with a dark yellow palate that commonly dries blue-green. The breeding system is allogamous. Plants commonly are single-stemmed and usually erect but sometimes produce decumbent-ascending stems branching from the base, these sometimes rooting at proximal nodes. Erythranthe unimaculata is known from Cochise, Gila, Pima, and Santa Cruz counties, Arizona, and from Doña Ana County, New Mexico.
