Habit | Annuals, slender-taprooted or fibrous-rooted, rarely with runners from basal nodes. | Perennials, stoloniferous, stolons thin, forming overwintering turions. |
Stems | erect, simple or branched, terete, sometimes 4-angled distally, (5–)30–60(–80) cm, glabrous, glaucous. |
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. |
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. |
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. |
Flowers | herkogamous, 1–16, from distal nodes, sometimes from nearly all, chasmogamous. |
herkogamous, 2 or 3, from medial to distal nodes. |
Styles | minutely hirtellous-puberulent. |
scabrous. |
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, with scattered red spots, palate ridges with 2 white patches at tips, bilaterally symmetric, strongly bilabiate; tube-throat funnelform, (12–)16–20(–24) mm, exserted beyond calyx margin; limb expanded 8–10 mm, lobes obovate-oblong, apex rounded to truncate. |
Fruiting pedicels | 10–50 mm, glabrous, glaucous. |
15–35 mm, densely glandular-villous, hairs 0.5–1.2(–1.5) mm, gland-tipped. |
Fruiting calyces | broadly campanulate, inflated, sagittally compressed, 7–16 mm, glabrous, glaucous, throat closing. |
plicate-angled, cylindric-urceolate, weakly inflated, 6–12 mm, densely glandular-villous, hairs 0.5–1.2(–1.5) mm, gland-tipped, lobes 1–2 mm, apex rounded to mucronate. |

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.) |
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).
