Habit | Annuals, taprooted. | Annuals, usually fibrous-rooted, rarely rooting at proximal nodes. |
Stems | erect, simple or branched from basal nodes, 4–17 cm, minutely puberulent. |
erect, sometimes decumbent-ascending, branched, 4–30 cm, minutely stipitate-glandular, also delicately villosulous-glandular along whole length. |
Leaves | cauline, basal not persistent; petiole 0 mm; blade pinnately veined, palmately 3-veined (in broader ones), linear to oblanceolate, (3–)4–17 × 1–4 mm, base attenuate, margins entire, apex acute to obtuse, surfaces minutely puberulent. |
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, 1–36, from distal or medial to distal nodes. |
plesiogamous, 1–6(–10), axillary at all nodes, chasmogamous. |
Styles | glabrous. |
glabrous. |
Corollas | pink to purple, abaxial limb with 2 yellow ridges, bilaterally symmetric, strongly bilabiate; tube-throat funnelform, 6–15 mm, exserted beyond calyx margin; limb expanded 8–15 mm, lobes deeply notched, abaxial limb sparsely bearded. |
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 | spreading horizontally, 5–33 mm. |
15–30(–55) mm, minutely stipitate-glandular, sometimes minutely hirtellous and minutely stipitate-glandular, sometimes short glandular-villous. |
Fruiting calyces | sometimes red-spotted on ribs, becoming straw colored, cylindric, 4–8 mm, margins distinctly toothed or lobed, glabrous, ribs weak, lobes pronounced, erect, margins ciliate. |
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 | Erythranthe palmeri has been confused with other closely related species, including E. diffusa, E. discolor (pink form), E. rhodopetra, and E. sierrae. It was previously thought to be a widely distributed species because of this taxonomic confusion but now is regarded as endemic to the Transverse Range in the San Bernardino and San Gabriel mountains.

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.
