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.

Vitis ×doaniana is endemic to well-drained soils of the Rolling Plains and Cross Timbers and Prairies regions in north central Texas and adjacent Oklahoma. Vitis ×doaniana is a hybrid between V. mustangensis and V. acerifolia, and was once more common in nature than it is at present. It was named for Judge J. Doan of Wilbarger County, Texas, who manufactured wine from the berries of this species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
