Habit Perennials, rhizomatous, sometimes producing numerous, long, remotely leafy runners from basal cauline nodes. Annuals, taprooted, densely compact.
Stems

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 0 mm;

blade 1-veined or palmately 3-veined (in broader ones), linear to lanceolate or ovate, 2–20(–25) × 0.5–4 mm, base attenuate, margins entire, apex acute to obtuse, surfaces minutely puberulent.
Flowers

herkogamous, (1 or)2–7(–14), from distal nodes.

herkogamous or plesiogamous, 1–72, from distal or 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.

yellow, throat sometimes with red markings, abaxial limb sometimes with a red dot, bilaterally symmetric, weakly bilabiate;

tube-throat cylindric, indistinct from throat, 4–6 mm, exserted beyond calyx margin;

limb expanded 2–3 mm, lobes entire or weakly notched, palate glabrous or sparsely bearded.
Fruiting pedicels

18–35(–40) mm, distals densely, minutely hirtellous, hairs often slightly deflexed.

2–10 mm.
Fruiting calyces

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.
