Stems | decumbent to procumbent, simple or branching near base, 5–38(–60) cm, densely glandular-villous, hairs 0.5–1.2(–1.5) mm, gland-tipped, internodes evident. |
erect or basally ascending-erect, simple or few-branched, becoming fistulose in larger plants, (2–)10–30(–100) cm, delicately short glandular-villous to stipitate-glandular, often glabrous below inflorescence. |
Leaves | cauline, basal not persistent; petiole 2–5(–20) mm; blade subpalmately to pinnately veined, broadly ovate to broadly lanceolate, 7–35(–40) × 8–25 mm, base rounded, margins sharply, irregularly dentate to denticulate, apex acute to obtuse, surfaces glandular-villous. |
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. |

pale yellow, palate and abaxial throat dark yellow, drying blue-green, red-spotted, bilaterally symmetric, bilabiate; tube-throat funnelform to subfunnelform, (7–)9–14 mm, exserted 3–4 mm beyond calyx margin; limb broadly expanded (8–17 mm pressed), palate densely bearded. |

Discussion | The occurrence of Erythranthe jungermannioides in the Columbia River Gorge of Klickitat County, Washington (the only record from the state of Washington), is based on an imprecise, unconfirmed observation from the early 1990s (Washington National Heritage Program 2005).

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.
