Discussion	Erythranthe linearifolia is endemic to serpentine substrates in Shasta, Siskiyou, and Trinity counties; typical E. primuloides occurs in the same area but not on serpentine. Erythranthe linearifolia is distinct from E. primuloides especially in its narrow leaves and cespitose habit. A collection from Tulare County appears to be E. linearifolia (Shevock 10597, CAS), but this appears to be far out of range and the voucher should be reexamined; it probably is better identified as an unusual collection of E. primuloides. (Discussion copyrighted by Flora of North America; reprinted with permission.)	Erythranthe barbata previously has been placed in synonymy with E. montioides but differs from it in having each corolla lobe deeply notched and a consistently bearded palate. In E. montioides, each corolla lobe is entire or shallowly notched, and the palate is glabrous or sparsely bearded. Erythranthe barbata is most abundant in Tulare County but also occurs in immediately adjacent Inyo and Kern counties. (Discussion copyrighted by Flora of North America; reprinted with permission.)
