Habit | Annuals, slender-taprooted or fibrous-rooted, rarely with runners from basal nodes. | Perennials, rhizomatous. |
Stems | erect, simple or branched, terete, sometimes 4-angled distally, (5–)30–60(–80) cm, glabrous, glaucous. |
erect to erect-ascending, simple or few-branched, 15–40 cm, coarsely pilose to hirsute-pilose, glabrescent, 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; petiole (0–)2–12 mm, not winged, distally sometimes sessile, subclasping; blade pinnately veined, lanceolate to ovate-lanceolate or elliptic-ovate, 25–75 mm, thick, base rounded to cuneate, margins coarsely dentate to serrate, apex acute to obtuse, surfaces coarsely pilose to hirsute-pilose, glabrescent. |
Flowers | herkogamous, 1–16, from distal nodes, sometimes from nearly all, chasmogamous. |

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.) |
Erythranthe dentata is distinctive and rarely misidentified. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
