Four stratigraphic logs were measured in detail at the Cacheuta hill (northwestern Mendoza Province, Argentina), and seven plantiferous levels were determined at Puesto Míguez and Agua de las Avispas. The systematic study of the paleoflora found in these localities is presented in this paper. Bryopsida, Lycopsida, Sphenopsida, Filicopsida and Gymnospermopsida (Corystospermales y Peltaspermales) are analized in this first contribution.
