The article presents the systematic composition and stratigraphic distribution of the Middle Jurassic flora of Ustyurt (Uzbekistan). In the Middle Jurassic sediments, three plant complexes of different ages are distinguished, corre-sponding to aalen, bayos and bath, differing from each other by the unequal species composition of Coniopteris ferns and Nilssonia cicadas. The change of complexes during the Middle Jurassic occurred gradually. The vegetation reached its greatest dawn in the Bajocian and Bata centuries.
