Discussion
Ziziphus parryi is known in the flora area only from Imperial, Riverside, San Bernardino, and San Diego counties, but the distribution continues southward in Baja California as far as Cedros Island. Small-leaved plants from southern Baja California have been identified as Z. parryi var. microphylla, but similar variants occur sporadically into California.
