--><p>The <i>Antennaria friesiana</i> complex consists of <i></i>subsp.<i> alaskana</i>, <i></i>subsp.<i> neoalaskana</i>, and <i></i>subsp.<i> friesiana</i>, the former two are dioecious (sexual) phases of the latter gynoecious (asexual) form. The sexual populations are known from Alaska and cordilleran areas of northern Yukon and adjacent Northwest Territories (R. J. Bayer 1991). The apomictic phase is almost circumpolar, occurring from the central and eastern Siberian plateau eastward across the North American arctic to Greenland (Bayer). E. Hultén (1968) circumscribed a fourth subspecies, <i>A. friesiana</i> subsp. compacta. After studying its morphology, in the field and herbarium, it is apparent that Hultén’s taxon contains at least three incongruous entities that are probably not at all related to the other two subspecies of <i>A. friesiana</i>. Hultén’s subsp. compacta included <i>A. densifolia</i>, which is recognized as a distinct species, and A. crymophila and A. neoalaskana as taxonomic synonyms. <i>Antennaria</i> compacta in the strict sense and A. crymophila are perhaps hybrid apomicts and are treated here in <i>A. alpina</i> (see Bayer for details). <i>Antennaria</i> neoalaskana is treated here as a subspecies of <i>A. friesiana</i>.</p>
