The Lipovtsy flora originates mostly from the synonymous Formation exposed at the coal quarries in the Razdolnaya( Suifun) River Basin in Heilongjiang Province( China) and Primorye Region( Russia). The thorough study of this flora has revealed its high diversity and abundance. One of the most prominent groups in the Lipovtsy flora is the ferns. Next in diversity are conifers( Miroviaceae,Taxodiaceae,Podozamitaceae,Taxaceae,Cephalotaxaceae). It was revealed the remarkable quantity of bennettitalean remains( 24 taxa). The main peculiarity of this flora is the appearance of first angiosperms( pollen,dispersed cuticle,leaves). The fine preservation of the cuticles from the coals allows us to research the taxonomical composition of peat-forming plants and clear main components of the swamp plant communities. These plants supplied the material for the accumulation of resinite coals on the territory of Razdolnaya River Basin were conifers Miroviaceae,taxodialeans,bennettites,as well as gleicheniaceous and cyatheaceous ferns.
