|discussion=<p>The range of <i></i></i>var.<i><i> purpuratum</i> is more southern and western (Gulf Coastal Plains) than that of <i></i></i>var.<i><i> concinnum</i> (mainly eastern Appalachians and Piedmont). Controversy surrounds the question of proper rank for this taxon. Semple suggests the rank of species. It is sometimes difficult to distinguish this variety from <i></i></i>var.<i><i> concinnum</i>, from which it differs by its mostly basal leaves, basal and proximal leaves persistent and more linear, and often more compact arrays (A. Cronquist 1980). When subspecies are recognized under <i>Symphyotrichum laeve</i>, it is uncertain whether var. attenuatum would constitute a separate subspecies or be part of <i></i></i>subsp.<i><i> concinnum</i>.</p>
