The organization of symmetry in a flower. Whole-flower symmetry, individual organ shape and developmental identity are distinct characters; similar outlines can arise through different molecular mechanisms.
A floral arrangement with one principal symmetry plane. Differential deployment of dorsal regulators can contribute, but a shared appearance does not establish one universal developmental mechanism.
A floral arrangement with multiple planes of symmetry around the reproductive axis. Its developmental basis can differ among lineages, so a derived radial flower need not restore the ancestral organ identities.
