synonym Rhus radicans L.; Toxicodendron means "poison tree"; while not a wildflower, recognition of this species is important since many people are allergic to the oil (urushiol) present in all parts of the plant year round; Gleason and Cronquist, 1991, recognize two variations, var. radicans puberulent which has scabrous or papillose fruits, var. negundo (Greene) Reveal has glabrous fruits or with a few scattered hairs, leaves generally toothed
