Habit | Annuals, taprooted. | Perennials, rhizomatous, sometimes producing numerous, long, remotely leafy runners from basal cauline nodes. |
Stems | erect, simple or branched from basal nodes, 2–20 cm, densely glandular-puberulent, hairs 0.05–0.1 mm, gland-tipped. |
erect, simple, 20–100 cm, distals densely, minutely hirtellous. |
Leaves | 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. |
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. |
Flowers | herkogamous, 1–8, from medial to distal nodes. |
herkogamous, (1 or)2–7(–14), from distal nodes. |
Styles | glabrous. |
minutely, prominently hirsutulous to villosulous. |
Corollas | 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. |
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. |
Fruiting pedicels | 4–12 mm, densely glandular-puberulent, hairs 0.05–0.1 mm, gland-tipped. |
18–35(–40) mm, distals densely, minutely hirtellous, hairs often slightly deflexed. |
Fruiting calyces | red-dotted, strongly angled, cylindric-campanulate, 4–7 mm, margins distinctly toothed or lobed, densely glandular-puberulent, hairs 0.05–0.1 mm, gland-tipped, ribs corky, lobes pronounced, spreading. |
green, sometimes red-spotted, ovoid, inflated, sagittally compressed, 15–19 mm, distals densely, minutely hirtellous, throat closing, lobe margins (sinuses) villous. |

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.
