Treatment

Rhus toxicodendron var. trilobata M.J. Young, Familiar Lessons Bot. View in CoL 197. 1873 (“ Trilobate ”), nom. nud.

Toxicodendron radicans (L.) Kuntze View in CoL , Revis. Gen. Pl. 1:153. 1891.

Young (1873) divided Rhus toxicodendron View in CoL L. ( = Toxicodendron View in CoL radicans) into four varieties. Three were noted explicitly and the fourth presumably was the nominate variety. No description accompanies R. toxicodendron var. trilobata View in CoL . Young (1873) simply states “Found in the northern part of Texas.” There is no indication that Young (1873) is proposing a new combination and change in status based on R. trilobata Nutt. View in CoL , which was described from the Rocky Mountains but also occurs in Texas.
