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, 0.5–10 cm, glabrous or minutely puberulent. |
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 0 mm; blade 1-veined or palmately 3-veined (in broader ones), linear to lanceolate or ovate, 2–8 × 1–5 mm, base attenuate, sometimes clasping, margins entire, sometimes toothed, apex acute, surfaces glabrous or minutely puberulent. |
Flowers | herkogamous, (1 or)2–7(–14), from distal nodes. |
herkogamous, sometimes plesiogamous, 1–22, from distal or medial to distal nodes. |
Styles | minutely, prominently hirsutulous to villosulous. |
glabrous. |

pink to purple, palate sometimes with yellow or pink markings, without yellow palate ridges, bilaterally symmetric, weakly bilabiate; tube-throat cylindric, 3–8 mm, exserted 2–3 mm beyond calyx margin; limb expanded 3–7 mm, lobes entire, sometimes notched, adaxial limb glabrous, sometimes sparsely bearded. |
Fruiting pedicels | 18–35(–40) mm, distals densely, minutely hirtellous, hairs often slightly deflexed. |
ascending to often spreading horizontally, 5–30 mm. |

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 androsacea occurs primarily in the southern half of California but is scattered as far north as Lake and Modoc counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
