This keys to Vitis rufotomentosa in the FSUS key (link)
And it keys to Vitis aestivalis in the key from FNA (link)
POWO, APA, and FNA all consider V. rufotomentosa to be a synonym of V. aestivalis, but Weakley and the Southeastern Flora Team have recognized it as its own distinct species. There is some interesting discussion of this species on NatureServe (link). I feel confident enough to mark this as V. rufotomentosa for now, although further research may change that.
Is image 4 the flower? I thought it was a bud at first, but I am not so sure. According to APA, the flower of this species is tubular and discoid. Seems like this might actually be the flower based on that, although I am having a hard time telling for sure.
