Habit | Perennials, rhizomatous. | Annuals, fibrous-rooted, sometimes apparently rooting at proximal nodes if stems proximally decumbent. |
Stems | erect, usually simple, (15–)25–60(–75) cm, stipitate-glandular to glandular-villous. |
erect, simple, 4-angled, 2–8 cm, slender, glabrous. |
Leaves | cauline; petiole 0 mm; blade palmately veined, elliptic to ovate, ovate-lanceolate, or broadly oblanceolate, (10–)25–75(–90) × 5–35 mm, base rounded to cuneate, subclasping, margins denticulate, subentire, or entire, apex acute, surfaces stipitate-glandular to glandular-villous. |
basal and cauline or basal deciduous, largest at mid stem or above, cauline relatively few on long internodes; petiole: basal and proximals to midcauline 1–4 mm, distals 0 mm; blade palmately 3-veined, ovate to ovate-lanceolate, 5–11 × 3–9 mm, base truncate to cuneate, margins very shallowly dentate or denticulate, apex acute to obtuse, surfaces glabrous or distals and bracteals sparsely villous, hairs vitreous, flattened, eglandular, multicellular. |
Flowers | herkogamous, 2–6(–10), axillary at leafy medial to distal nodes. |
plesiogamous, (1–)4–10, sometimes from all nodes, usually beginning about mid stem, cleistogamous. |

Corollas | purple, rarely crimson, pale violet, white, pinkish white, yellowish white, or lavender, sometimes lined with red dots, bilaterally symmetric, strongly bilabiate; tube-throat funnelform, 22–28 mm, exserted beyond calyx margins; lobe apex usually truncate to shallowly convex, shallowly retuse, throat open. |
yellow, usually red-dotted, bilaterally or nearly radially symmetric, bilabiate or nearly regular; tube-throat narrowly cylindric, 4–6 mm, exserted 0.5–1 mm beyond calyx margin; limb barely expanded. |

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 hallii is known from Boulder, Clear Creek, Fremont, Grand, Jefferson, Larimer, Routt, and Saguache counties. The Colorado population system is morphologically and geographically coherent. Erythranthe hallii is similar to E. arvensis; both have four-angled stems, autogamous reproduction, a tendency to root at basal nodes and distally, and both have bracteal leaves villous with vitreous, flattened, eglandular, multicellular hairs, although this vestiture is barely developed and often absent in E. hallii. The only reported chromosome number from the Colorado plants (2n = 32) also appears to be distinct among possible relatives of E. hallii.
