Thank you for the correction. I suspect that the plant pictured is Staghorn Sumac:
Not Poisonous. Unlike its close relatives, poison ivy, oak and sumac, the landscape sumacs do not cause itchy rashes. Vine- and shrub-like poison ivy and oak have three distinct leaflets per leaf, so there is no confusing those. But poison sumac (Toxicodendron vernix) is also a small tree with leaves like regular sumac and Staghorn Sumac except Poison Sumac has smooth not saw-toothed or serrated leaves.
