This is one of 3 versions of a poison sumac plant. They all contain urushiol- a substance causing your skin to break out. The first two are named for other plants because of leaf shape. The shape of the leaf of the tree is the most mundane. Most literature say the tree is the most dangerous of the three poison sumacs. Most folks rank thes in terms of reaction as follows Poison Ivy < Poison Oak < Poison Sumac Tree.
