Discussion | Antennaria umbrinella is a primary sexual progenitor of the A. rosea complex (R. J. Bayer 1990b). It is characterized by somewhat erect, slightly woody stolons and phyllaries that are usually various shades of brown, sometimes white, or streaked with pink or rose (Bayer 1987b).

Antennaria argentea is distinguished by its robustly stoloniferous habit and silvery white phyllaries. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
