Habit | Perennials, rhizomatous, sometimes producing numerous, long, remotely leafy runners from basal cauline nodes. | Perennials, rhizomatous, densely cespitose, forming large patches and turfs 0.3–1 m diam. |
Stems | erect, simple, 20–100 cm, distals densely, minutely hirtellous. |
erect to ascending, simple, 2–10 cm, sparsely hirsute and stipitate-glandular, internodes shortened. |
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. |
basal or near basal, sometimes proximal cauline, subrosulate; petiole 0 mm; blade 1-veined or palmately 3-veined, linear to narrowly oblanceolate, 15–50 × 1.5–5 mm, base long-cuneate, often subclasping, margins entire, dentate-serrate, or distally dentate, apex acute, surfaces glabrous or adaxial sparsely short-pilose, eglandular. |

herkogamous, 1. |
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, red-spotted or -striped, bilaterally symmetric, weakly bilabiate, loosely hirsute on abaxial side of opening; tube-throat narrowly campanulate, 18–22 mm, exserted beyond calyx margin; lobes broadly obovate-oblong, apex rounded- or truncate-notched, throat open. |
Fruiting pedicels | 18–35(–40) mm, distals densely, minutely hirtellous, hairs often slightly deflexed. |

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.

Erythranthe linearifolia is endemic to serpentine substrates in Shasta, Siskiyou, and Trinity counties; typical E. primuloides occurs in the same area but not on serpentine. Erythranthe linearifolia is distinct from E. primuloides especially in its narrow leaves and cespitose habit. A collection from Tulare County appears to be E. linearifolia (Shevock 10597, CAS), but this appears to be far out of range and the voucher should be reexamined; it probably is better identified as an unusual collection of E. primuloides.
