Discussion | 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.
