|discussion=<p><i>Antennaria microphylla</i> is a primary sexual progenitor of the <i>A. rosea</i> polyploid agamic complex (R. J. Bayer 1990b). A. Cronquist (1955) included <i>A. rosea</i> within his circumscription of <i>A. microphylla</i>. It is preferable to recognize sexual diploids as distinct from their morphologically discrete hybrid apomictic derivatives. <i>Antennaria microphylla</i> is always dioecious and has stems distally stipitate-glandular and white phyllaries; <i>A. rosea</i> is always gynoecious and has stems without glandular hairs and phyllaries only occasionally white.</p><!--
--><p>Some authors (A. E. Porsild 1950; E. H. Moss 1959; Porsild and W. J. Cody 1980) have recognized A. nitida as distinct; comparisons of the nomenclatural types of the two show that they are conspecific. <i>Antennaria microphylla</i> has allelopathic properties (G. D. Manners and D. S. Galitz 1985).</p>
