--><p><i>Viguiera</i> has been long recognized as paraphyletic. Molecular studies are helping to clarify its phylogeny, and the corresponding systematic adjustments are beginning (E. E. Schilling and J. L. Panero 2002). Some groups have already been separated, including <i>Bahiopsis</i> and <i>Heliomeris</i>. It is likely that the genus will be narrowed to include only a single species, <i>V. dentata</i> (including <i>V. helianthoides</i> Kunth), and that new or resurrected genera will accommodate the remaining species. As currently circumscribed, the genus occurs primarily in Mexico and South America and reaches its northern limit of distribution in the southwestern United States. The Mexican (Chihuahua, Durango) V. phenax was collected a single time in Texas [where it was named <i>Helianthus</i> ludens Shinners and <i>Viguiera</i> ludens (Shinners) M. C. Johnston]; it apparently has not become established in the flora area.</p>
