Vitis mustangensis

Its range includes parts of Mississippi, Alabama, Louisiana, Texas, and Oklahoma.

[1][2] This woody species produces small clusters of hard green fruit that ripen into soft 3⁄4-inch (2 cm) dark purple berries between July –September.

This variety of grape is recognized by the leaves that have a white velvet-like underside and lobed, cordate shape.

These vines often cover trees, shrubs, fences and other objects that it grows near.

[4] The fruit can be potentially irritating to the skin when handled, and are mildly unpleasant to eat raw because of bitterness and a high acidity content.
