Abstract

Permian flora of West Angaraland contains many predecessors of the Mesozoic floras. Conifers of the area do not show evident links with Mesozoic members of the group, but they are phylogenetically significant because they do not fit current versions of the coniferalean phylogeny. In this respect the most interesting are representatives of the family Cardiolepidaceae (female capsules Cardiolepis, seeds Nucicarpus, leaves Phylladoderma, and Vesicaspora-like pollen), and the genera Sashinia gen. nov. and Slivkovia. Moot points of the coniferalean phylogeny proposed by Florin are discussed.
