Antennaria parlinii
Antennaria rosulata
Subspecies 2 (2 in the flora).
The Antennaria parlinii complex consists of two fairly distinct subspecies that differ in induments of basal leaves (tomentose in subsp. fallax; glabrous in subsp. parlinii) and other characters (R. J. Bayer and G. L. Stebbins 1982). Antennaria parlinii is the most common eastern North American species (Bayer and Stebbins 1982, 1983). This complex of polyploid sexual and apomictic populations is the result of multiple hybridizations among sexual diploid species including A. plantaginifolia, A. racemosa, and A. solitaria (Bayer 1985b; Bayer and D. J. Crawford 1986). A. Cronquist (1945; H. A. Gleason and Cronquist 1991) included A. parlinii within his circumscription of A. plantaginifolia. By not including the hybrid polyploiid within the circumscription of a single one of its sexual progenitors, the circumscription here better portrays the evolutionary relationships between A. parlinii and its sexual progenitors.

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.
