Habit | Annuals, slender-taprooted or fibrous-rooted, rarely with runners from basal nodes. | Annuals, shallowly fibrous-rooted. |
Stems | erect, simple or branched, terete, sometimes 4-angled distally, (5–)30–60(–80) cm, glabrous, glaucous. |
ascending, geniculate at nodes, branched at proximal and medial nodes, 4–15 cm, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, sometimes minutely hirtellous, hairs sharp-pointed, eglandular. |
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. |
usually cauline, basal usually deciduous by flowering; petiole 1–3 mm; blade palmately 3-veined, narrowly ovate or narrowly lanceolate to elliptic or elliptic-lanceolate, largest 5–15 × 2–6 mm, relatively even-sized, or slightly reduced distally, base attenuate, margins entire, mucronulate, or denticulate, apex acute to obtuse, surfaces minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, sometimes minutely hirtellous, hairs sharp-pointed, eglandular. |
Flowers | herkogamous, 1–16, from distal nodes, sometimes from nearly all, chasmogamous. |
plesiogamous, 10–20, from medial to distal nodes. |
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, red-spotted or striped, bilaterally symmetric, weakly bilabiate; tube-throat cylindric to narrowly funnelform, 3.5–5 mm, not exserted beyond calyx margin; limb barely widened, lobes broadly obovate, apex rounded. |
Fruiting pedicels | 10–50 mm, glabrous, glaucous. |
straight, 5–11 mm, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, sometimes minutely hirtellous, hairs sharp-pointed, eglandular. |
Fruiting calyces | broadly campanulate, inflated, sagittally compressed, 7–16 mm, glabrous, glaucous, throat closing. |
winged, plicate-angled, campanulate becoming ovoid-ellipsoid to campanulate, distinctly inflated, 5–6 mm, margins distinctly toothed or lobed, sparsely, minutely hirtellous, eglandular, sometimes sparsely sessile-glandular, lobes pronounced, erect. |
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.) |
