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.

Varieties 5 (4 in the flora).

Vitis cinerea var. tomentosa (Planchon) Comeaux is endemic to northeastern Mexico (B. L. Comeaux and J. Lu 2000).

Vitis cinerea is sometimes confused with V. aestivalis; see the discussion under that species. Vitis cinerea as defined here is highly variable and is in need of field studies and phylogeographic analysis, along with its tropical relatives V. biforma Rose and V. tiliifolia. Wan Y. et al. (2013) concluded that V. cinerea is not monophyletic.
