Habit | Perennials, rhizomatous or stoloniferous, mat-forming, rhizomes or stolons flagelliform. | Annuals, usually fibrous-rooted, rarely rooting at proximal nodes. |
Stems | erect to ascending, usually simple, 2–10(–20) cm, villous, internodes shortened. |
erect, sometimes decumbent-ascending, branched, 4–30 cm, minutely stipitate-glandular, also delicately villosulous-glandular along whole length. |
Leaves | all basal or near basal, often rosulate; petiole 0 mm; blade palmately 3-veined, oblanceolate to elliptic-obovate, 7–40 × 4–12 mm, base cuneate to attenuate, margins entire, distally denticulate to dentate, or sharply serrate-dentate, apex acute to obtuse, abaxial surface glabrous, adaxial glabrous or glabrate to sparsely to densely long-villous, eglandular. |
basal and cauline; petiole 1–3 mm, cauline blade slightly or hardly reduced in size from basal, becoming subsessile to sessile (1–3 pairs of cauline leaves); blade palmately 3(–5)-veined, orbicular-ovate to oblong-ovate, 7–28 × 5–22 mm, base truncate to shallowly cuneate, margins shallowly dentate to denticulate, teeth 3–6 per side, apex rounded to obtuse, surfaces villous, hairs thin-walled, vitreous, eglandular or minutely gland-tipped, usually also minutely stipitate-glandular. |
Flowers | herkogamous, 1. |
plesiogamous, 1–6(–10), axillary at all nodes, chasmogamous. |
Styles | glabrous. |
glabrous. |
Corollas | yellow to orange-yellow, usually brown-spotted abaxially, base of each abaxial lobe usually with a larger reddish brown spot, bilaterally or nearly radially symmetric, weakly bilabiate or nearly regular, densely hirsute on abaxial side of opening; tube-throat narrowly campanulate, 15–20 mm, exserted beyond calyx margin; lobes broadly obovate-oblong, apex rounded- or truncate-notched, throat open, palate densely villous, abaxial ridges prominent. |
light yellow, red-spotted, weakly bilaterally symmetric, ± bilabiate; tube-throat narrowly funnelform, 5–7 mm, exserted 1–2 mm beyond calyx margin; limb expanded 2–4 mm. |
Fruiting pedicels | 30–110(–130) mm, glabrous or sparsely stipitate-glandular near base. |
15–30(–55) mm, minutely stipitate-glandular, sometimes minutely hirtellous and minutely stipitate-glandular, sometimes short glandular-villous. |
Fruiting calyces | tubular-campanulate, weakly or not inflated, 6–8 mm, glabrous. |
nodding 90º at maturity, usually 3(–5)-veined, ovoid, inflated, sagittally compressed, 6–10 mm, minutely stipitate-glandular, throat closing, lobes usually 3 or 3 and 5 on same plant, if 5 then with 2 interpolated lobes much smaller than abaxial pair. |

Discussion | Flowers in Erythranthe primuloides and E. linearifolia characteristically appear to be scapose, but the scapes are pedicels arising from axils of greatly foreshortened stems. Occasionally in both species the internodes may lengthen somewhat, and the leaves are not so densely clustered at the base of the stems. In northern Klamath, western Deschutes, and eastern Douglas counties, Oregon, an area within the range of typical populations, Erythranthe primuloides has distinctively large corollas (limbs 10–15 mm wide). Apparent clones of large-flowered and smaller-flowered plants sometimes grow in close proximity or even intermixed, appearing as two different entities.

Erythranthe calciphila is recognized by its annual duration (fibrous-rooted), short, erect stems with few, even-sized leaves (the basal often persistent), delicate stipitate-glandular vestiture, three-lobed calyces that are relatively large in fruit, small corollas, and autogamous reproduction. Plants rarely root at proximal nodes. In Arizona, at the northernmost extremity of its range, E. calciphila occurs in the Chiricahua, Huachuca, and Mule mountains of Cochise County.
