Dig deeper at SERNEC, a consortium of southeastern herbaria.
On first glance it looks much like Poison-oak (Toxicodendron pubescens) and less so Poison-ivy (T. radicans), with its three-parted leaves. However, the central (terminal) leaflet of Fragrant Sumac tapers gradually to the base, and appears rather diamond-shaped, unlike the more rounded base of the terminal Poison-oak or Poison-ivy leaflet with a short stalk showing. The leaves of Fragrant Sumac also tend to be rather thick, and they are usually not as shiny as the leaves of Poison-oak or Poison-ivy. Read more at Vascular Plants of North Carolina.
The specific epithet is Latin for “aromatic” or “fragrant,” describing the strong and pleasant scent of the crushed leaves. Read more at "Know Your Natives" from the Arkansas Native Plant Society.
