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). Antennaria pulcherrima is characterized by relatively large basal leaves, rhizomatous growth, and dark-colored phyllaries, each with a relatively large black spot at the base (R. J. Bayer and G. L. Stebbins 1987). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
