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. |
ascending to ascending-erect, geniculate at nodes, usually many-branched from base, 3–10(–25) cm, short stipitate-glandular or sessile-glandular, hairs 0.1–0.3 mm, 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. |
basal and cauline, largest at base or near mid stem, sometimes unreduced in size up to distalmost nodes; petiole 0 mm; cauline blade palmately 3(–5)-veined, ovate to ovate-lanceolate, 8–26(–35) mm, base abruptly cuneate to rounded, sometimes subauriculate, margins entire or barely mucronulate to shallowly dentate-mucronulate, teeth or mucronulae 1–3 per side, apex acute to rounded, surfaces short stipitate-glandular or sessile-glandular, hairs 0.1–0.3 mm, gland-tipped. |
Flowers | herkogamous, 1–16, from distal nodes, sometimes from nearly all, chasmogamous. |
plesiogamous, (1–)3–12, 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. |
white to pinkish or flesh colored, rarely yellowish, throat and abaxial lobes red-spotted, nearly radially symmetric; tube-throat cylindric, 5–6(–8) mm, exserted beyond calyx margin; limb barely widened, lobes broadly obovate, apex rounded. |

straight, 11–28 mm, short stipitate-glandular or sessile-glandular, hairs 0.1–0.3 mm, gland-tipped. |
Fruiting calyces | broadly campanulate, inflated, sagittally compressed, 7–16 mm, glabrous, glaucous, throat closing. |
purplish, prominently 5-angled, tubular-campanulate or ovoid-ellipsoid, strongly inflated, 8–12 mm, margins distinctly toothed or lobed, short stipitate-glandular or sessile-glandular, hairs 0.1–0.3 mm, gland-tipped, lobes pronounced, erect. |

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 distinction between Erythranthe latidens and E. inflatula sometimes seems arbitrary, perhaps because of gene exchange where they are sympatric in northwestern California. Erythranthe latidens in Oregon is known only from southern Harney County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
