Discussion | Antennaria neglecta is a sexual progenitor of both the A. howellii and A. parvifolia polyploid complexes and has one of the more widespread ranges among the amphimictic species in the genus in North America. Amphimicts generally have small ranges compared to those of the polyploid agamic complexes derived from them. Characteristic features of A. neglecta are its lashlike stolons that bear reduced leaves (except at the ends), flags on the distal cauline leaves, and basal leaves that are green-glabrescent with age (R. J. Bayer and G. L. Stebbins 1982). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
