Resolved Question: Why are flowers considered as organ but not as organ system?

As definition, organ should be a group of cells performing similar or same function working together. Organ system should be a group of organs functioning together for a same task (like digesting, or breathing). So, a flower consists at least two organs, Carpel (female reproductive organ), and Stigma (male reproductive organ), which are both aiming at reproductive purpose. So, by definition, I think flower should be considered as organ system instead. However, currently only Brooker's Biology supports this point of view, Campbell, Raven, Starr, and most of Bio textbooks all says that flower should be simply an organ. Could someone explain to me why should flower be considered as organ but not organ system please. Thanks more
