Leaves of Liriodendrites Johnson were found in the Gyliakian (Santonian) and Boshnyakovo (Danian) floras of Sakhalin Island, Rarytkin, Koryak, and Kakanaut (Maastrichtian) floras of the Koryak Upland, and Antibes (Coniacian) flora of western Siberia. The study of new finds and revision of earlier collections resulted in the erection of a new species, L. occidentalis P. Alekseev, sp. nov., and creation of two new combinations, L. sachalinensis (Krysht.) P. Alekseev, comb. nov. and L. aeternus (Golovn.) P. Alekseev, comb. nov. The geographical and stratigraphic ranges of Liriodendrites in the Northern Hemisphere were reviewed.
