|discussion=<p>subspecies 2 (2 in the flora)</p><!--
--><p>Some authors have recognized Antennaria microcephala (= A. luzuloides subsp. aberrans) as a distinct species. Given the intergradation between A. luzuloides in the strict sense and A. microcephala in the strict sense, one species with two subspecies seems justified. Perhaps the most significant difference between the subspecies is ecologic. Antennaria luzuloides is a member of the Argenteae group.</p>
