Discussion | Antennaria pulchella is the diploid progenitor of A. media and, consequently, a progenitor of the A. alpina complex (R. J. Bayer 1990d). The A. rosea and A. parvifolia complexes also have the genome of A. pulchella, shown in the high elevation clones with dark phyllaries in these two polyploid complexes. Antennaria pulchella is differentiated from A. media by shorter pistillate or staminate corollas and shorter cauline leaves (Bayer). This sexually reproducing diploid ranges from the area around Lake Tahoe to the Mt. Whitney region (Bayer). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
