Winged sumac (Rhus copallinum). The picture shows the winged rachis that is not evident in the other species of sumac. This Rhus copallinum is growing along the State Road 26 roadside in front of the Purdue Wildlife Area a few miles west of campus. Like the more common smooth sumac, winged sumac shows beautiful fall color. This one is just starting to show color, the picture was taken Sept. 29, 2009, so it should be redder by now.
