Habit | Annuals, slender-taprooted or fibrous-rooted, rarely with runners from basal nodes. | Annuals, fibrous-rooted or filiform-taprooted. |
Stems | erect, simple or branched, terete, sometimes 4-angled distally, (5–)30–60(–80) cm, glabrous, glaucous. |
erect to ascending, straight or geniculate at nodes, usually many-branched, terete, 5–25 cm, moderately puberulent-glandular to villous-glandular, hairs 0.1–0.8 mm, flattened, sometimes vitreous, distinctly multicellular, gland-tipped. |
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. |

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 washingtonensis is considered to be extirpated in Washington by the Washington Natural Heritage Program. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
