M. Whalen (1977) recognized two varieties of Bebbia juncea: var. aspera, which occurs in the flora area and in northern Mexico, and var. juncea, which occurs in Mexico (Baja California and Baja California Sur). Variety juncea has generally broader, obtuse, rounded or apiculate, ovate to elliptic phyllaries.
