Discussion | Subspecies 4 (4 in the flora). The Antennaria howellii (previously A. neodioica) polyploid complex is highly variable morphologically; four more or less distinct subspecies can be recognized within it. The sexual progenitors of the complex are A. neglecta, A. plantaginifolia, A. racemosa, and A. virginica (see R. J. Bayer 1985). Antennaria marginata may also be a minor contributor to the origins of the complex. A. Cronquist (H. A. Gleason and Cronquist 1991) included members of this complex in A. neglecta; I maintain, because these apomicts are of hybrid polyploid origin from among multiple sexual progenitors, they best not be included within the circumscription of any one sexual progenitor (Bayer 1989d).

Antennaria racemosa is characterized by adaxially glabrous basal leaves and open, racemiform to paniculiform arrays of heads (R. J. Bayer 1985b). The young leaves have a slight odor of citronella when crushed. Antennaria racemosa has a pivotal sexual genome of the Catipes group and has contributed to the origin of clones in the A. howellii, A. parlinii, and A. rosea polyploid agamic complexes (Bayer 1985, 1985b, 1990b).
