--><p><i>Symphyotrichum ericoides</i> resembles <i>S. pilosum </i>var.<i> pilosum</i>, which has larger heads, longer rays, and phyllaries that are not spine-tipped, though the revolute margins can make them appear so. Two subspecies and four weakly separated varieties of <i>S. ericoides</i> were recognized by A. G. Jones (1978). Tetraploids of <i></i>var.<i> ericoides</i> on the eastern prairies can be difficult to distinguish from <i>S. falcatum</i>. A number of aster cultivars are sold under the name “<i>Aster</i> ericoides.” These are all derived from European garden plants and are either cultivars of <i>S. dumosum</i>, <i>S. lateriflorum</i>, <i>S. pilosum</i>, or <i>S. racemosum</i>, or hybrids involving one of those species and another taxon. The misapplication of the epithet ericoides dates back to the nineteenth century and has persisted in the horticultural literature.</p>
