|discussion=<p>Variety dasycephala occurs primarily at high elevations in the western cordillera, extending eastward onto the northern prairies, and disjunctively in the Canadian arctic (Caribou Hills). It is more readily distinguished from <i></i>var.<i> glauca</i> southward, where the two varieties are ± elevationally separated. Difficulty in separating them occurs northward, where they are nearer each other and pockets of complete introgression occur, e.g., southeastern British Columbia and southwestern Alberta. Hybrids with <i>Agoseris aurantiaca</i> and <i>A. parviflora</i> also occur.</p><!--
--><p>Variety dasycephala contains regional phases that exhibit a step-clinal distribution. The large number of synonyms reflects the variation. As circumscribed here, <i></i>var.<i> dasycephala</i> encompasses most of what has been called <i>Agoseris glauca</i> var. agrestis (see discussion under <i></i>var.<i> glauca</i>).</p>
