Antennaria howellii
Antennaria flagellaris
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 flagellaris is among the more distinctive species of Antennaria, with its flagelliform stolons (whiplike with leaves only at the very end) and heads borne singly. It belongs to the Dimorphae group (R. J. Bayer 1990; Bayer et al. 1996).
