Antennaria umbrinella
Antennaria rosulata
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 rosulata is easily recognizable by its silvery gray leaves, dense, humifuse growth form, and heads borne singly (R. J. Bayer 1987b). Its distribution is centered on the four corners area (Bayer and G. L. Stebbins 1987). It has probably contributed to the origins of some of the clones of A. rosea with low stature and low numbers of flowering heads that are found in Arizona, Colorado, New Mexico, and Utah.
