--><p><i>Artemisia campestris</i> varies; each morphologic form grades into another. The present circumscription is conservative in that only three subspecies are recognized; the subspecies usually can be separated geographically as well as morphologically. Populations in western North America consist primarily of <i></i>subsp.<i> pacifica</i>; east of the continental divide, plants are assigned to <i></i>subsp.<i> canadensis</i> in northern latitudes and to <i></i>subsp.<i> caudata</i> in southern latitudes.</p>
