Every iris flower is actinomorphous (has central symmetry). Its most conspicuous three "petals" are actually sepals, their widest, most beautiful parts collectively forming a limb of the flower. The three spoon-like structures are reduced petals. Style is divided into three flat petaloid branches, to which 3 stamens are appressed (not visible, as they are covered by style branches). Style branches are also covering and thus blocking from view the basal, narrow parts of sepals (claws).
