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.
