Habit | Perennials, rhizomatous, sometimes producing numerous, long, remotely leafy runners from basal cauline nodes. | Perennials, stoloniferous, stolons thin, forming overwintering turions. |
Stems | erect, simple, 20–100 cm, distals densely, minutely hirtellous. |
decumbent to procumbent, simple or branching near base, 5–38(–60) cm, densely glandular-villous, hairs 0.5–1.2(–1.5) mm, gland-tipped, internodes evident. |
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, basal not persistent; petiole 2–5(–20) mm; blade subpalmately to pinnately veined, broadly ovate to broadly lanceolate, 7–35(–40) × 8–25 mm, base rounded, margins sharply, irregularly dentate to denticulate, apex acute to obtuse, surfaces glandular-villous. |
Flowers | herkogamous, (1 or)2–7(–14), from distal nodes. |

scabrous. |
Corollas | yellow to chrome yellow, throat floor and tube usually red-spotted, bilaterally symmetric, bilabiate; tube-throat broadly funnelform, 18–26 mm, exserted (8–)10–15 mm beyond calyx margin; limb expanded 22–30 mm. |
yellow, with scattered red spots, palate ridges with 2 white patches at tips, bilaterally symmetric, strongly bilabiate; tube-throat funnelform, (12–)16–20(–24) mm, exserted beyond calyx margin; limb expanded 8–10 mm, lobes obovate-oblong, apex rounded to truncate. |
Fruiting pedicels | 18–35(–40) mm, distals densely, minutely hirtellous, hairs often slightly deflexed. |
15–35 mm, densely glandular-villous, hairs 0.5–1.2(–1.5) mm, gland-tipped. |

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 occurrence of Erythranthe jungermannioides in the Columbia River Gorge of Klickitat County, Washington (the only record from the state of Washington), is based on an imprecise, unconfirmed observation from the early 1990s (Washington National Heritage Program 2005).
