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.) |
In addition to the features noted in the key and descriptions, the fruiting calyces of Erythranthe grayi are distinctly more inflated than those of E. acutidens and E. inconspicua. G. L. Nesom (2012g) maintained E. grayi as distinct from E. acutidens, relying primarily on fruiting pedicel length (see key above), but the two have nearly identical ranges (Tuolumne County south to Kern County), and study of additional collections suggests that only a single species may be represented.
