|discussion=<p>The population in Baja California is disjunct from the closest range in Arizona and northern <i>Nevada</i>.</p><!--
--><p>Plants glabrous and glandular on the phyllaries, stems, and leaves have been recognized as <i></i>var.<i> macranthus</i>; they intergrade with hairier forms and do not show a coherent geographic pattern. Plants commonly identified as <i>Erigeron subtrinervis</i> var. conspicuus usually have stems sparsely hirsuto-pilose with hairs 1–1.5 mm, and the leaves commonly are ciliate on the margins and veins. As implied in the nomenclatural combination by Breitung, those plants are more similar to <i>E. speciosus</i> than to <i>E. subtrinervis</i>, and they apparently show part of the greater variability of <i>E. speciosus</i> in the northwestern part of its range (Alberta, British Columbia, Idaho, Montana, Oregon, Washington, and Wyoming), where more typical plants also occur. <i>Erigeron speciosus</i> and <i>E. subtrinervis</i> are sympatric over large parts of their ranges and appear to be at least partially reproductively isolated entities, although intermediates are frequently encountered.</p>
