how can you tell a hermi from a male plant?

these two plants originally looked like they would be nice strong females but once i put them into the flower cycle they started to develop seed sacs and such. Can a hermi pollenate other normal females? Here are pics of the two in question.DSC02667.jpgDSC02669.jpgDSC02665.jpgDSC02666.jpgDSC02668.jpg
