Leaves

cauline, basal not persistent;

petiole 2–5(–20) mm;

blade subpalmately to pinnately veined, broadly ovate to broadly lanceolate, 7–35(–40) × 8–25 mm, base rounded, margins sharply, irregularly dentate to denticulate, apex acute to obtuse, surfaces glandular-villous.

tube-throat funnelform, (12–)16–20(–24) mm, exserted beyond calyx margin;

limb expanded 8–10 mm, lobes obovate-oblong, apex rounded to truncate.

5–10 mm in proximal axils, shorter than or equal to subtending leaves, 1–5 mm distally and flowers and fruits appearing sessile or subsessile, glabrous.
Fruiting calyces

plicate-angled, cylindric-urceolate, weakly inflated, 6–12 mm, densely glandular-villous, hairs 0.5–1.2(–1.5) mm, gland-tipped, lobes 1–2 mm, apex rounded to mucronate.

red-tinged to sparsely purple-dotted or not, broadly elliptic-ovoid, inflated, sagittally compressed, 10–13 mm, minutely hirtellous, throat not or slightly closing.

Discussion

The occurrence of Erythranthe jungermannioides in the Columbia River Gorge of Klickitat County, Washington (the only record from the state of Washington), is based on an imprecise, unconfirmed observation from the early 1990s (Washington National Heritage Program 2005).

Erythranthe brachystylis is closely similar to E. arvensis. Plants of both are annual in duration and produce depressed-ovate leaves, the distal with vitreous-villous surfaces, and tiny corollas barely exserted from the calyx and probably cleistogamous. Vestiture of the distal leaves includes an admixture of eglandular sharp-pointed hairs, sometimes encountered in E. arvensis, though not typical, perhaps reflecting introgression from E. nasuta.

The distinction of Erythranthe brachystylis from E. arvensis is primarily in its foreshortened pedicels and more inflated fruiting calyces. The fruiting calyces appear to be subsessile or on pedicels shorter or only equaling the subtending leaves. The difference is essentially qualitative but produces a distinctive aspect.

Erythranthe brachystylis is known only from the type collection in Nye County, a region where E. arvensis has not been documented.
