--><p>Galinsoga is closely related to Sabazia Cassini of Mexico and South America and to at least some members of Alloispermum Willdenow, primarily from South America. Galinsoga might best be treated as a single larger genus including Alloispermum and Sabazia (J. M. Canne 1978; J. L. Panero et al. 1999).</p>
