Discussion | Erythranthe purpurea is restricted to the San Bernardino Mountains in San Bernardino County and is disjunct in the Sierra San Pedro Mártir in Baja California, Mexico. (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.
