Discussion

Antennaria plantaginifolia is a diploid progenitor of the A. parlinii complex and is similar to that species except for smaller heads and adaxially gray-pubescent basal leaves (R. J. Bayer and G. L. Stebbins 1982; Bayer 1985b; Bayer and D. J. Crawford 1986). It is a diploid ancestor of the A. howellii complex. It is found in the Appalachian region; disjunct populations occur in the driftless area of Wisconsin and Minnesota (Bayer and Stebbins).
