Abstract

New species of angiosperms are described as members of the genus Macclintockia from the Ugol’naya Bay area, in northeastern Russia: M. barykovensis Moiseeva, sp. nov., M. gigantea Moiseeva, sp. nov., and M. terranea Moiseeva et Herman, sp. nov. Leaves of this genus are considerably variable, which hampers differentiation between particular species. The study of new material has allowed the author to trace the morphological variability of these species and revised on this ground the composition of the species M. ochotica Vachr. et Herman and M. beringiana Herman. The composition of Macclintockia is discussed, as well as its occurrence during the Late Cretaceous.
