Poison ivy ( Toxicodendron radicans and toxicodendron rydbergii ), poison oak ( Toxicodendron diversilobum and toxicodendron pubescens ), and poison sumac ( toxicodendron vernix) plants all produce urushiol; you won’t be able to differentiate the specific plant you brushed up against by the rash it produces. But here’s the thing—it doesn’t really matter. Each of these three plants all make urushiol, and it’s the urushiol that makes you miserable.
