--><p>Subgenus <i>Symphyotrichum</i> has been divided into three sections: sect. Conyzopsis (x = 7), sect. <i>Symphyotrichum</i> (including sect. Turbinelli) (x = 8), and sect. Occidentales (x = 8). Relationships among sections remain unresolved, and it is uncertain whether sect. <i>Symphyotrichum</i>, for instance, is monophyletic as defined here or elsewhere (e.g., G. L. Nesom 1994b).</p>
