Discussion | F. W. Pennell (1947, 1951) considered Erythranthe arenicola an endemic of Monterey County, but plants from adjacent San Luis Obispo and Santa Cruz counties also belong here. Most of the localities are at seaside, but some are more than a mile inland. Erythranthe arenicola is hypothesized here to be a derivative of E. guttata or E. grandis, retaining the herkogamous breeding system of its putative ancestor but reduced in size and duration.
