Discussion
In the flora area, Frangula betulifolia is found in southeastern Arizona, the southern two-thirds of New Mexico, and trans-Pecos Texas. It and F. obovata are allopatric and morphologically distinct. C. B. Wolf (1938) considered a collection from Cochise County in southeastern Arizona, named as Rhamnus blumeri (Frangula ×blumeri), to be a hybrid between Frangula betulifolia and F. californica var. ursina; see the discussion of the latter taxon for more information.
