Discussion
This species is noteworthy for having the upper one-third to one-half of the inner surface of the corolla-lobes glabrous, glabrate, or only partly pubescent down the center in contrast to the lower half, which is densely villosulous. Additional distinguishing characters of this taxon are the short, few-flowered peduncles, the very small leaf-blades with only 2-3 tufts of barbate hairs in the axils of the lower leaf-surface, and the obsolete lateral nerves.
