Etymology

Toxicodendron comes from Greek parts toxikon 'poison' (seen in English toxic) and dendron 'tree', like the familiar plant name rhododendron. So Toxicodendron is basically a 'poison tree', which explains why plants in this group, such as poison ivy and poison oak, can cause skin irritation.
