Though the leaves look a bit like Poison-ivy (Toxicodendron radicans), Hoptree has entire leaflets with no stalks to the leaflets. American Bladdernut (Staphylea trifolia) also is a tall shrub or small tree with three leaflets, but the leaflets are serrated and the flowers (white) and fruits (large bag-like capsules) are considerably different. Some references split out this species into a handful of varieties or subspecies. Read more at Vascular Plants of North Carolina.
