Habit | Annuals, shallowly fibrous-rooted. | Perennials, rhizomatous, sometimes producing numerous, long, remotely leafy runners from basal cauline nodes. |
Stems | erect, straight at nodes, simple or few-branched at base, 5–12(–18) cm, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped. |
erect, simple, 20–100 cm, distals densely, minutely hirtellous. |
Leaves | basal and cauline; petiole 2–9 mm, distinctly 3-veined, 2-winged; blade palmately 3-veined, elliptic-oblong to ovate or oblanceolate, 3–14(–23) × 2–9(–15) mm, base cuneate to attenuate, margins denticulate to entire, apex acute to obtuse, surfaces minutely stipitate-glandular, hairs 0.1–0.3 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, 1–9, from medial to distal nodes. |
herkogamous, (1 or)2–7(–14), from distal nodes. |
Styles | glabrous. |
minutely, prominently hirsutulous to villosulous. |
Corollas | yellowish, tube-throat, palate ridges, and limb yellow to pale yellow, abaxial limb red-dotted or not, bilaterally symmetric, weakly bilabiate; tube-throat funnelform, 6–9 mm, exserted beyond calyx margin; lobes broadly obovate-suborbicular, apex rounded. |
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 | divergent-arcuate, 12–38 mm, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped. |
18–35(–40) mm, distals densely, minutely hirtellous, hairs often slightly deflexed. |
Fruiting calyces | cylindric, ± inflated, 7–10 mm, margins distinctly toothed or lobed, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, lobes pronounced, erect. |

Discussion | Erythranthe pulsiferae is characterized by minutely stipitate-glandular vestiture (lacking villous hairs), elongate internodes, persistent basal leaves, small, palmately veined, cauline leaves with short, three-veined petioles and elliptic-oblong to ovate or oblanceolate blades, divergent-arcuate pedicels, and small, all yellow, weakly bilabiate corollas.

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.
