|discussion=<p>Intergrades (probable hybrids) between <i>Ageratina aromatica</i> and <i>A. altissima</i> were identified by A. F. Clewell and J. W. Wooten (1971) over a broad area of their sympatry. They also found intergrades between <i>A. aromatica</i> and <i>A. jucunda</i> where their ranges meet.</p>
