Lee for what it's worth, that cluster of leaves you posted isn't from any dogwood I've ever seen before. It more resembles something in the hickory nut family but for some reason I can't postitively ID it either. The leaves are compound, smooth edged, glossy, and 6 to a cluster and that resembles something in the nut family of trees. I've seen a bunch of those around here where I live, but I'll be damned if I can find one on the net that looks exactly like it so I can make a positive ID. I'll keep looking and digging and see what I can come up with............check back later.
