Discussion | In several early publications (for example, T. V. Munson 1909), Vitis mustangensis was known as V. candicans Engelmann ex A. Gray. M. O. Moore (1991) argued that the name V. candicans is ambiguous and not identifiable with any species based on the original description, making the more recent name V. mustangensis the valid and legitimate one for this species.
