文摘In Jurassic sediments of Siberia, remains of Lycopodites are rare in occurrence. They are represented by two species ： Lycopodites tenerrimus Heer, and L. （.9） trichiatus Pryn. This paper presents an emended diag- nosis of the species L.（.9） trichiatus Pryn., and the descriptions of two new species： Lycopodhes subulifolius sp. nov., and L. baikalensis sp. nov. from the Early-Middle Jurassic sediments of the Irkutsk coal basin, Eastern Siberia, Russia.
