Habit | Perennials, rhizomatous, sometimes producing numerous, long, remotely leafy runners from basal cauline nodes. | Annuals, taprooted. |
Stems | erect, simple, 20–100 cm, distals densely, minutely hirtellous. |
erect, simple or branched from basal nodes, 2–20 cm, densely glandular-puberulent, hairs 0.05–0.1 mm, 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, basal not persistent; petiole 1–4 mm; blade 1-veined or palmately 3-veined (in broader ones), linear-oblanceolate to linear-lanceolate or linear, (5–)10–15(–20) × 1–2(–5) mm, base attenuate, margins entire or remotely mucronulate distally, apex acute, surfaces densely glandular-puberulent, hairs 0.05–0.1 mm, gland-tipped. |
Flowers | herkogamous, (1 or)2–7(–14), from distal nodes. |
herkogamous, 1–8, from medial to distal nodes. |
Styles | minutely, prominently hirsutulous to villosulous. |
glabrous. |
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. |
pink to red, rose red, red-purple, or lavender, throat usually light purple to lavender (similar in color to rest of corolla), palate ridges yellow, abaxial limb with deep pink markings, bilaterally symmetric, strongly bilabiate; tube-throat cylindric-funnelform, 3–7 mm, exserted 0–1 mm beyond calyx margin; limb expanded 2–3 mm, lobes notched or entire. |
Fruiting pedicels | 18–35(–40) mm, distals densely, minutely hirtellous, hairs often slightly deflexed. |
4–12 mm, densely glandular-puberulent, hairs 0.05–0.1 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.
