Etymology:
The genus Palafoxia is in honor of perhaps Josè Rebolledo de Palafox y Melzi (1776-1847), Duke of Saragossa. However, a paper published by Hervè M. Burdetin suggests that the first choice name was originally to honor and commemorate Juan de Palafox y Mendoza (1600-1659), who was a bishop and founder of the University of Mexico. The paper further suggests this is so because the other Palafox, Josè Regolledo de Palafox y Melzi became a national hero and the attribution was transferred to him.

The species epithet "arida" means "growing in dry places" or "dry land".
