usually cauline, basal sometimes persistent, distal connate-perfoliate, often bractlike; petiole: proximals 4–10(–15) mm, distals 0 mm; blade: proximals sometimes subpinnately veined, usually with (1 or)2 pairs arising from midvein above base, becoming palmately veined distally, ovate-lanceolate to ovate or broadly ovate-elliptic, mid cauline 12–40(–50) × 10–25(–45) mm, base rounded to truncate or cuneate, margins shallowly dentate-serrate to serrate, teeth 7–12 per side, apex rounded to obtuse, surfaces glabrous, sometimes with sharp-pointed hirtellous, vitreous-flattened, or gland-tipped hairs. |

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 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.
