Two new species of Ginkgo with dissected leaves, Ginkgo sertensis N. Nosova et Golovn., sp. nov. and G. chlonoviae N. Nosova et Golovn., sp. nov., from the upper Albian deposits of the Kiya Formation of Western Siberia are described. These species expand the taxonomic composition of the Serta flora and supplement our understanding of the systematic diversity and distribution of Ginkgo in the Cretaceous of Russian Asia.
