Habit | Annuals, slender-taprooted or fibrous-rooted, rarely with runners from basal nodes. | Perennials, rhizomatous, sometimes producing numerous, long, remotely leafy runners from basal cauline nodes. |
Stems | erect, simple or branched, terete, sometimes 4-angled distally, (5–)30–60(–80) cm, glabrous, glaucous. |
erect, simple, 20–100 cm, distals densely, minutely hirtellous. |
Leaves | basal and cauline; petiole: basal and proximal cauline as long as or much longer than blade, slender, sometimes pubescent or villous, distals absent; blade palmately 3–5-veined, (proximal) ovate to ovate-elliptic or orbicular-ovate, sometimes subcordate, 10–50 mm, midcauline to distal orbicular, 5–45 mm wide, distinctly connate-perfoliate, disclike distally, base rounded to subcordate, margins: proximals denticulate to dentate or coarsely, irregularly toothed, sometimes lobed at base, distals nearly entire or toothed, teeth scattered, small, apex rounded, surfaces glabrous, glaucous. |
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, 1–16, from distal nodes, sometimes from nearly all, chasmogamous. |
herkogamous, (1 or)2–7(–14), from distal nodes. |
Styles | minutely hirtellous-puberulent. |
minutely, prominently hirsutulous to villosulous. |
Corollas | yellow, sometimes with a median splotch, abaxial limb densely dark yellow, others much lighter, throat floor and tube red-dotted, bilaterally symmetric, bilabiate; tube-throat funnelform, 12–23 mm, exserted 4–8 mm beyond calyx margin; limb expanded 14–36 mm. |
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 | 10–50 mm, glabrous, glaucous. |
18–35(–40) mm, distals densely, minutely hirtellous, hairs often slightly deflexed. |
Fruiting calyces | broadly campanulate, inflated, sagittally compressed, 7–16 mm, glabrous, glaucous, throat closing. |
green, sometimes red-spotted, ovoid, inflated, sagittally compressed, 15–19 mm, distals densely, minutely hirtellous, throat closing, lobe margins (sinuses) villous. |

Discussion | Plants from one locality in Butte County are unusual in producing filiform, small-leaved runners from basal cauline nodes. Erythranthe glaucescens is known only from Butte and Tehama counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
