Habit | Annuals, shallowly fibrous-rooted. | Annuals, usually fibrous-rooted, rarely rooting at proximal nodes. |
Stems | ascending, geniculate at nodes, branched at proximal and medial nodes, 4–15 cm, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, sometimes minutely hirtellous, hairs sharp-pointed, eglandular. |
erect, sometimes decumbent-ascending, branched, 4–30 cm, minutely stipitate-glandular, also delicately villosulous-glandular along whole length. |
Leaves | usually cauline, basal usually deciduous by flowering; petiole 1–3 mm; blade palmately 3-veined, narrowly ovate or narrowly lanceolate to elliptic or elliptic-lanceolate, largest 5–15 × 2–6 mm, relatively even-sized, or slightly reduced distally, base attenuate, margins entire, mucronulate, or denticulate, apex acute to obtuse, surfaces minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, sometimes minutely hirtellous, hairs sharp-pointed, 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 | plesiogamous, 10–20, from medial to distal nodes. |
plesiogamous, 1–6(–10), axillary at all nodes, chasmogamous. |

Corollas | yellow, red-spotted or striped, bilaterally symmetric, weakly bilabiate; tube-throat cylindric to narrowly funnelform, 3.5–5 mm, not exserted beyond calyx margin; limb barely widened, lobes broadly obovate, apex rounded. |
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 | straight, 5–11 mm, minutely stipitate-glandular, hairs 0.1–0.3 mm, gland-tipped, sometimes minutely hirtellous, hairs sharp-pointed, eglandular. |
15–30(–55) mm, minutely stipitate-glandular, sometimes minutely hirtellous and minutely stipitate-glandular, sometimes short glandular-villous. |
Fruiting calyces | winged, plicate-angled, campanulate becoming ovoid-ellipsoid to campanulate, distinctly inflated, 5–6 mm, margins distinctly toothed or lobed, sparsely, minutely hirtellous, eglandular, sometimes sparsely sessile-glandular, lobes pronounced, erect. |
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 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.
