|discussion=<p>C. B. Wolf (1938) considered a collection from Cochise County in southeastern Arizona named as <i>Rhamnus</i> blumeri Greene [<i>Frangula</i> ×blumeri (Greene) Kartesz & Gandhi] to be a hybrid between <i>Frangula californica</i> var. ursina and <i>F. betulifolia</i>. 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 <i>F. betulifolia</i> and <i>F. californica</i> is not common.</p>
