Discussion
With its relatively large, 3–5-nerved, basal leaves and relatively large heads borne singly, Antennaria solitaria is an easily recognized amphimictic member of the Catipes group (R. J. Bayer and G. L. Stebbins 1982). It is a sexual diploid progenitor of the A. parlinii polyploid complex.
