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, 4–20 cm, minutely puberulent. |
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), lanceolate to ovate, 3–20 × 1–6 mm, base attenuate, margins entire, sometimes toothed, apex acute, surfaces minutely puberulent. |
Flowers | herkogamous, 1–16, from distal nodes, sometimes from nearly all, chasmogamous. |
herkogamous, 1–36, from distal or medial to distal nodes. |
Styles | minutely hirtellous-puberulent. |
distally pubescent. |
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. |
pink to purple, abaxial limb with 2 yellow palate ridges, bilaterally symmetric, weakly bilabiate; tube-throat funnelform, (3–)6–10 mm, exserted beyond calyx margin; limb expanded 3–14 mm, lobes notched, adaxial limb glabrous, sometimes sparsely bearded. |
Fruiting pedicels | 10–50 mm, glabrous, glaucous. |
ascending to spreading horizontally, (2–)12–60(–68) 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 diffusa has been included previously in E. palmeri but can be distinguished morphologically by glabrous margins on the calyx and pubescence on the distal end of the style. It occurs in Orange, Riverside, and San Diego counties as well as close to the California border in Baja California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
