Amoreuxia gonzalezii appears to be intermediate in morphology between A. palmatifida and A. wrightii. It has leaves with 7(9) spatulate lobes and seed coats hairy, similar to those of A. palmatifida, and seeds globose, similar to A. wrightii. Molecular phylogenetic data indicate that A. gonzalezii and A. wrightii are more closely related to each other than either is to A. palmatifida (S. B. Johnson-Fulton 2014).
Amoreuxia gonzalezii is very rare. In the United States, fewer than five populations have been found, primarily in two locations. Over its entire range, it is known to occur in fewer than ten localities. Major threats are alien species and herbivory by cattle, which find it very palatable. As with A. palmatifida, all parts of A. gonzalezii, especially the root, have been used as a food source by indigenous tribes in southwestern United States and northern Mexico (W. C. Hodgson 2001; H. H. Poppendieck 1980).
Amoreuxia gonzalezii is in the Center for Plant Conservation’s National Collection of Endangered Plants.
