Antennaria parvifolia
Antennaria parlinii
Antennaria parvifolia is a widespread, polyploid complex of sexual (dioecious) and asexual (gynoecious) populations (G. L. Stebbins 1932b; R. J. Bayer and Stebbins 1987). Although variable morphologically, no infraspecific taxa seem warranted at this time. Sexual (dioecious) populations are known primarily from New Mexico and Colorado; apomictic plants occur throughout the range of the species. Probable sexual diploid/tetraploid progenitors of the A. parvifolia complex include A. dioica, A. marginata, A. neglecta, and A. pulchella/A. media. Antennaria parvifolia is characterized by relatively short stature and relatively small numbers of relatively large heads. The epithet parvifolia has been rendered as “parviflora” in floras, e.g., key in Great Plains Flora Association (1986); E. H. Moss (1959); H. J. Scoggan (1978–1979, part 4). In some floras, A. parvifolia has been confused with A. microphylla; the two are probably not closely related.

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.
