--><p>Although traditionally included within Viguiera, the species of Bahiopsis differ by their distinctive base chromosome number and form a basally diverging clade in subtribe Helianthinae, based on molecular data. Morphologically, they are most similar to Calanticaria, another segregate of Viguiera that is Mexican in geographic distribution, from which they differ by their branched capitulescences and having phyllaries in which the apical herbaceous portions are longer.</p>
