Habit | Perennials, rhizomatous, rooting at proximal nodes, sometimes producing creeping, small-leaved runners, forming matted colonies, rhizomes filiform. | Annuals, fibrous-rooted. |

erect to ascending, simple or branched from base, 4-angled, 3–16 cm, glabrous. |
Leaves | basal and cauline; petiole: proximals 2–5 mm, distals 0 mm; blade often purple beneath, palmately 3-veined, orbicular to narrowly elliptic or ovate, proximals usually sublyrate, 3–12 mm, becoming larger distally, base cuneate to a short petiole, margins entire, mucronulate, or barely denticulate, apex obtuse, surfaces sparsely to moderately puberulent, hairs minute, stipitate-glandular. |

Discussion | Erythranthe caespitosa is endemic to northwestern and central Washington (Cascade and Olympic mountains) and adjacent British Columbia (Cascades, Selkirk Mountains and Chilliwack Valley, Coast Mountains). The plants have consistently small leaves with subentire margins, and the stems are consistently procumbent to decumbent-ascending, usually forming matted colonies. Erythranthe caespitosa and E. tilingii appear to be sympatric in counties of northwestern Washington, but this needs to be verified in the field.

Erythranthe inconspicua occurs in Sierran counties from Kern north to El Dorado and then is apparently disjunct further northward to Butte County. A record from Los Angeles County (Bigelow s.n., 14 May 1854, the type of the species) is probably mislabeled, as other collections by Bigelow on the same day are from Calaveras County.
