Mapping here is provisional. This taxon is often included with A. parlinii ssp. fallax (Greene) Bayer & Stebbins, but appears somewhat intermediate between typical plantaginifolia and parlinii (Cr. FNA 19, W). It differs from typical parlinii in its basal leaves, with upper surfaces initially tomentose and "more tardily glabrate" (versus glabrous or nearly so even when young). Also, summits of young flowering stems are usually glandless (versus usually with purple glandular hairs). Further examination of colls. is needed to clarify the degree of distinction among these three or more taxa in Ky.
