Resumen:
The finding of arborescent lycophytes in tbe Tupe Forrnation, Sierra de Maz,province of La Rioja is reported in the present papel´. Bank imprints and a large stem are described as Lycopodiopsis derbyi, ?Brasilodendron pedroanum, and two other unnamed forms.They are comparable to Permian specimens from Chubut Province (Argentina) and Brasil. Previous paleoclimatic inferences about the U pper Paleozoic of Argentina, based on the ahsence of arborescent lycophytes in the Paganzo Basin, are discussed. According to palynological investigations, the Tupe Formation is not older than Late Carboniferous.
