Discussion | Erythranthe lewisii in California occurs in Modoc, Siskiyou, and Trinity counties. California records from Shasta County and south previously identified as E. lewisii are identified here as E. erubescens. The record for E. lewisii in Alaska is documented by this collection: Hyder [noted on handwritten label as "New to Alaska, Standley"], damp land, 27 June 1924, K. Whited 1291 (MO). Apparent exceptions to the characteristic flower color are these: white to lavender in Nevada (Clark County, Charleston Mountains, Train 2068, MO); pinkish white in Washington (Skamania and Yakima counties, Mt. Paddo, Suksdorf 5779, MO); white or tinged with yellow, in Wyoming (Teton County, as described by Nelson in the protologue of Mimulus lewisii var. tetonensis).

Erythranthe hardhamiae is endemic to the central coast region in Monterey and San Luis Obispo counties. The species was previously included in E. palmeri but can be distinguished by having a wider limb (16–25 mm) than E. palmeri (8–15 mm) and pale pink flowers with a broad yellow palate and orifice. In contrast, E. palmeri has deep pink flowers with two yellow ridges on the palate. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
