limb expanded 5–8 mm.

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

15–30(–55) mm, minutely stipitate-glandular, sometimes minutely hirtellous and minutely stipitate-glandular, sometimes short glandular-villous.
Fruiting calyces

obtriangular to broadly obtriangular or deeply cupulate, inflated, sagittally compressed, (7–)8–12 mm, sparsely short villous-glandular or glabrous, throat not closing, lateral lobes shallowly convex-mucronulate, adaxial ovate with apex rounded.

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 geyeri has commonly been regarded as conspecific with E. glabrata (Kunth) G. L. Nesom (as Mimulus glabratus var. jamesii), but typical E. glabrata has a different chromosome number and distinct morphology and its range does not reach the United States. In Mexico, the two species are broadly sympatric without intermediates. An allozyme study of the M. glabratus complex (R. K. Vickery 1990) indicated that the Great Plains populations of E. geyeri are distinct from those in New Mexico and Mexico, corresponding to a difference in pedicel vestiture.

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.
