Última Gymnospermous woods from Jejenes Formation, Carboniferous of San Juan, Argentina: Abietopitys petriellae (Brea and Césari) nov. comb. 41 Pujana,Roberto R.. Fossil woods from Carboniferous sediments of the Jejenes Formation are described and a new combination Abietopitys petriellae is proposed based on new and the original material. The wood is pycnoxylic with primitive characters such as abundant pits in radial walls of tracheids in an alternate disposition. The ray cells have peculiar wall thickenings. The primary xylem has a mesarch protoxylem. The species is compared with other Paleozoic woods; its botanical affinity remains uncertain.
