Habit | Perennials, rhizomatous, sometimes producing numerous, long, remotely leafy runners from basal cauline nodes. | Perennials, stoloniferous, sometimes also rhizomatous. |
Stems | erect, simple, 20–100 cm, distals densely, minutely hirtellous. |
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 | cauline, basal usually not persistent; petiole: proximals 8–25 mm, midcauline 3–5 mm, distalmost 0 mm; blade palmately (3–)5–7-veined, broadly ovate-triangular to ovate-lanceolate, 20–50(–60) × 10–30(–40) mm, usually 1–2 times longer than wide, base rounded to truncate to shallowly cuneate, margins dentate, teeth sharp-pointed, apex acute, surfaces sometimes glabrate, distals densely, minutely hirtellous. |
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 or)2–7(–14), from distal nodes. |

Discussion | Erythranthe decora is distinct in its uniformly ovate to ovate-lanceolate leaf blades with truncate bases and regularly toothed margins, relatively long internodes, rhizomatous habit, mostly unbranched stems, often with leafy runners from basal nodes, large corollas, hairy styles, and minutely hirtellous stems, pedicels, calyces, and leaf surfaces. The densely produced rhizomes suggest a relationship with the E. tilingii group. A population in Clearwater County, Idaho, appears to be long-disjunct from the main range of the species in northwestern Oregon and the western half of Washington.

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.
