| Poison Sumac, Poison Elder, Poison Dogwood, Swamp Sumac, Poison-wood, Poison-tree|
Poison sumac will be found growing in the wet areas of East Texas, east to Florida and north to Minnesota. Its 5- to 15-inch-long smooth and somewhat shiny pinnate leaves have 7 to 13 entire (smooth around the margin) leaflets which become orange or scarlet in the autumn. Its yellow-brown wood has horizontal lenticils on grey or brown bark. Poison sumac is closely related to poison ivy and poison oak, which are vines and usually have only 3 coarsly toothed leaflets rather than the 7 to 13 entire leaflets. "Toxico" means "poison tree" and refers to poison sumac's extremely dangerous and rash-producing properties. A high grade varnish is made from its sap.
