Discussion | Subspecies 4 (4 in the flora). Antennaria rosea is the most widespread Antennaria of North America, occurring in dry to moist habitats from near sea level to the alpine zone. The A. rosea polyploid agamic complex is one of the more morphologically diverse complexes of North American Antennaria. It occurs from the western cordillera of North America from southern California, Arizona, and New Mexico north to subarctic Alaska and east to Greenland and, disjunctly, in the Canadian maritime provinces, eastern Quebec, and immediately north of and adjacent to Lake Superior (R. J. Bayer et al. 1991). Antennaria chilensis (including A. chilensis var. magellanica) is a Patagonian endemic that morphologically fits within the circumscription of A. rosea and may well be an amphitropical disjunct member of the complex. Antennaria rosea is taxonomically confusing; it includes agamospermous microspecies that have been recognized as distinct taxonomic species. Morphometric and isozyme analyses have demonstrated that the primary source of morphologic variability in the complex derives from six sexually reproducing progenitors, A. aromatica, A. corymbosa, A. pulchella, A. microphylla, A. racemosa, and A. umbrinella (R. J. Bayer 1989b, 1990b, 1990c). Additionally, three other sexually reproducing species, A. marginata, A. suffrutescens, and A. rosulata, may have contributed to the genetic complexity of the A. rosea complex (Bayer 1990b). Here, four reasonably distinct subspecies are recognized within the complex. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Antennaria plantaginifolia is a diploid progenitor of the A. parlinii complex and is similar to that species except for smaller heads and adaxially gray-pubescent basal leaves (R. J. Bayer and G. L. Stebbins 1982; Bayer 1985b; Bayer and D. J. Crawford 1986). It is a diploid ancestor of the A. howellii complex. It is found in the Appalachian region; disjunct populations occur in the driftless area of Wisconsin and Minnesota (Bayer and Stebbins).
