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.) |
Known only from the northern Rockies, Antennaria aromatica is characterized by glandulosity, cuneate leaves, and odor of citronella in crushed leaves of living material. It is most closely related to A. densifolia of the Northwest Territories and Yukon (R. J. Bayer 1989c). Some collections of pistillate plants from Colorado and other areas of the Rockies superficially resemble A. aromatica and undoubtedly have A. aromatica in their parentage. They are non-glandular and odorless and are closer to the type of A. pulvinata, which is included in the circumscription of A. rosea, as A. rosea subsp. pulvinata (Bayer). Antennaria aromatica is a sexual progenitor of the A. rosea and A. alpina polyploid complexes. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
