OK, I need help with this one. About three feet high, growing along the Scenic Highway in Cranberry Wilderness, July 13, 2014. See the second frame (below) for leaves. These will make dandy 24 inch prints!

Update: Thanks to my friends at the West Virginia Native Plant Society who identified it for me. It is Oenothera biennis. I have to find a way to turn off auto spell correction! it keeps changing these latin names! Lets see if it sticks this time.
