Another specimen of the same plant. Again, I think it is evening primrose (Oenothera biennis).

I'm not sure which flower this is. This is why you always take a good field guide with you. I believe that it is evening primrose (Oenothera biennis), but picking flowers in the preserve is not allowed, and I did not take more diagnostic photographs.
