Habit | Annuals, slender-taprooted or fibrous-rooted, rarely with runners from basal nodes. | Perennials, rhizomatous or stoloniferous, mat-forming, rhizomes or stolons flagelliform. |
Stems | erect, simple or branched, terete, sometimes 4-angled distally, (5–)30–60(–80) cm, glabrous, glaucous. |
erect to ascending, usually simple, 2–10(–20) cm, villous, internodes shortened. |
Leaves | basal and cauline; petiole: basal and proximal cauline as long as or much longer than blade, slender, sometimes pubescent or villous, distals absent; blade palmately 3–5-veined, (proximal) ovate to ovate-elliptic or orbicular-ovate, sometimes subcordate, 10–50 mm, midcauline to distal orbicular, 5–45 mm wide, distinctly connate-perfoliate, disclike distally, base rounded to subcordate, margins: proximals denticulate to dentate or coarsely, irregularly toothed, sometimes lobed at base, distals nearly entire or toothed, teeth scattered, small, apex rounded, surfaces glabrous, glaucous. |
all basal or near basal, often rosulate; petiole 0 mm; blade palmately 3-veined, oblanceolate to elliptic-obovate, 7–40 × 4–12 mm, base cuneate to attenuate, margins entire, distally denticulate to dentate, or sharply serrate-dentate, apex acute to obtuse, abaxial surface glabrous, adaxial glabrous or glabrate to sparsely to densely long-villous, eglandular. |
Flowers | herkogamous, 1–16, from distal nodes, sometimes from nearly all, chasmogamous. |
herkogamous, 1. |
Styles | minutely hirtellous-puberulent. |
glabrous. |
Corollas | yellow, sometimes with a median splotch, abaxial limb densely dark yellow, others much lighter, throat floor and tube red-dotted, bilaterally symmetric, bilabiate; tube-throat funnelform, 12–23 mm, exserted 4–8 mm beyond calyx margin; limb expanded 14–36 mm. |
yellow to orange-yellow, usually brown-spotted abaxially, base of each abaxial lobe usually with a larger reddish brown spot, bilaterally or nearly radially symmetric, weakly bilabiate or nearly regular, densely hirsute on abaxial side of opening; tube-throat narrowly campanulate, 15–20 mm, exserted beyond calyx margin; lobes broadly obovate-oblong, apex rounded- or truncate-notched, throat open, palate densely villous, abaxial ridges prominent. |
Fruiting pedicels | 10–50 mm, glabrous, glaucous. |
30–110(–130) mm, glabrous or sparsely stipitate-glandular near base. |
Fruiting calyces | broadly campanulate, inflated, sagittally compressed, 7–16 mm, glabrous, glaucous, throat closing. |
tubular-campanulate, weakly or not inflated, 6–8 mm, glabrous. |
Capsules | included, 5–11 mm. |

Discussion | Plants from one locality in Butte County are unusual in producing filiform, small-leaved runners from basal cauline nodes. Erythranthe glaucescens is known only from Butte and Tehama counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Flowers in Erythranthe primuloides and E. linearifolia characteristically appear to be scapose, but the scapes are pedicels arising from axils of greatly foreshortened stems. Occasionally in both species the internodes may lengthen somewhat, and the leaves are not so densely clustered at the base of the stems. In northern Klamath, western Deschutes, and eastern Douglas counties, Oregon, an area within the range of typical populations, Erythranthe primuloides has distinctively large corollas (limbs 10–15 mm wide). Apparent clones of large-flowered and smaller-flowered plants sometimes grow in close proximity or even intermixed, appearing as two different entities.
