Structure, peculiarities of morphogenesis and evolutional transformation of winged fruits in representatives of the family Celastraceae R. Br. are considered. Four types of such fruits are distinguished: I – winged fruits – fruits, outgrowths of which are formed due to radial expansion of the pericarp in the dorsal side of the carpel along the axis of the fruit (Tripterygioideae, subgenus Kalonymus genus Euonymus); II – the fruits with winged perianth – fruits, alar outgrowths of which are formed by elements of the perianth (Monimopetalum); III – divided winged fruit – divided fruits-capsules, wingshaped blades of which are formed from proliferating in the axial plane of the carpels (Hippocrateoideae); IV – winged schizocarpium – divided fruit, each mericarpium of which is provided by 3 alar vascularized outgrowths emerging due to the radial expansion of the pericarp from places of carpels fusion and in the dorsal side of the carpel along the axis of fruit (Stackhousioideae). We demonstrated that winged fruits appeared in different subfamilies and tribes.
