Well, at the risk of adding more confusion, there's this variety of Rhus aromatica that Dr. Vines put in his central Texas (Edwards Plateau) tree book, the only R. aromatica he covers there.

But Dr. Van Auken of UTSA. just identified the common local version as R. aromatica and left it at that. I'll leave it at that also. I have a few of them here. They look much like the pic that Hazel posted. No berries on mine right now. Ever handled the berries? Some sticky oily-feeling stuff on them. And BTW, has anyone ever seen this sumac?
