Habit | Annuals, slender-taprooted or fibrous-rooted, rarely with runners from basal nodes. | Annuals, taprooted. |
Stems | erect, simple or branched, terete, sometimes 4-angled distally, (5–)30–60(–80) cm, glabrous, glaucous. |
erect, simple or branched from basal nodes, 2–14.5 cm, sparsely glandular-pubescent, internodes elongate, distinct. |
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 0 mm; blade 1-veined or palmately 3-veined (in broader ones), linear to lanceolate, 5–15 × 0.5–2 mm, base attenuate, margins entire, apex acute to obtuse, surfaces sparsely glandular-pubescent. |
Flowers | herkogamous, 1–16, from distal nodes, sometimes from nearly all, chasmogamous. |
herkogamous, 1–30, from distal or 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. |
bicolored (abaxial limb yellow with red spots, adaxial maroon-purple) or yellow, bilaterally symmetric, strongly bilabiate; tube-throat cylindric, (5–)8–15 mm, exserted beyond calyx margin; limb expanded 6–15 mm, lateral lobes 2-fid, palate bearded. |
Fruiting pedicels | 10–50 mm, glabrous, glaucous. |
ascending to often spreading horizontally, (5–)9–25 mm. |
Fruiting calyces | broadly campanulate, inflated, sagittally compressed, 7–16 mm, glabrous, glaucous, throat closing. |

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 barbata previously has been placed in synonymy with E. montioides but differs from it in having each corolla lobe deeply notched and a consistently bearded palate. In E. montioides, each corolla lobe is entire or shallowly notched, and the palate is glabrous or sparsely bearded. Erythranthe barbata is most abundant in Tulare County but also occurs in immediately adjacent Inyo and Kern counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
