Discussion
C. B. Wolf (1938) considered a collection from Cochise County in southeastern Arizona named as Rhamnus blumeri Greene [Frangula ×blumeri (Greene) Kartesz & Gandhi] to be a hybrid between Frangula californica var. ursina and F. betulifolia. Study of an isotype of R. blumeri, and specimens of Wolf 2592 (MO), 2593 (MO), 2595 (MO), and Wolf & Everett 11384 (TEX), essentially corroborate the observations by Wolf. However, from examination of numerous other collections of both species from the Chiricahua Mountains, it appears that hybridization between F. betulifolia and F. californica is not common.
