Discussion

Vitis arizonica is variable and intergrades with V. girdiana in southern Nevada; it is in need of in-depth field and experimental studies. Some authors have recognized two varieties of this species (vars. arizonica and glabra), but the characters used to distinguish them intergrade so freely that their recognition does not seem justified.
