|discussion=<p>A. G. Jones (1989) suggested that <i>Symphyotrichum oolentangiense</i> hybridizes with <i>S. drummondii</i> and <i>S. laeve</i>. Two color morphs, <i>Aster</i> azureus Lindley forma incarnatus Farwell and “forma albidus” (the latter not validly published and incorrectly attributed to Steyermark by M. L. Fernald 1950), have been described but are not recognized here.</p>
