Prenanthes alba

I found these in bloom last August near Mio, Michigan. They are probably Prenanthes alba or white lettuce. Wind and rain prevented me from getting a descent shot with the lens stopped down so 34 images later I was able to get this final image from a Pmax stack. The flower was in heavy shade too. There's a few artifacts left to edit, but most of them have been corralled! K5 IIs (300mm f4 + 32mm extension 1/250sec at f4.5, ISO 800)..................Jim
