Habit | Annuals, slender-taprooted or fibrous-rooted, rarely with runners from basal nodes. | Perennials, stoloniferous, sometimes also rhizomatous. |
Stems | erect, simple or branched, terete, sometimes 4-angled distally, (5–)30–60(–80) cm, glabrous, glaucous. |
scandent to pendent, usually simple, 5–30(–40) cm, villous-glandular to minutely stipitate-glandular, hairs often a mixture of longer and much shorter ones, 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. |
cauline; petiole 0 mm; blade palmately 3-veined, flabellate distally to obovate to oblanceolate or elliptic, (5–)13–40(–55) × 8–20(–25) mm, largest near mid stem or distally, thick, base cuneate to rounded, subclasping, margins coarsely serrate on distal 1/2, apex acute, surfaces villous-glandular to minutely stipitate-glandular, hairs often a mixture of longer and much shorter ones, gland-tipped. |
Flowers | herkogamous, 1–16, from distal nodes, sometimes from nearly all, chasmogamous. |
herkogamous, 2–8, axillary at leafy medial to distal nodes. |
Styles | minutely hirtellous-puberulent. |
glabrous. |

scarlet to orange-red or orange, palate red, not spotted or striped, bilaterally symmetric, strongly bilabiate; tube-throat narrowly funnelform, 20–30 mm, exserted 5–15 mm beyond calyx margin; throat open, palate puberulent. |
Fruiting pedicels | 10–50 mm, glabrous, glaucous. |
10–30(–40) 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.) |
The range of Erythranthe eastwoodiae appears to be essentially contiguous with that of E. verbenacea in the Grand Canyon region, but there is no evidence of hybridization. Erythranthe eastwoodiae (as Mimulus eastwoodiae) is in the Center for Plant Conservation’s National Collection of Endangered Plants.
