Some classic outcrops (Acampamento Velho, Cambai Grande, Morro Papaléo and Budó) of the Itararé Group in Rio Grande do Sul (Brazil) are reviewed critically. Several fossil plant genera, previously registered only for Acampamento Velho and Morro Papaléo, were recognized also at Cambai Grande, being relevant the presence of Rubidgea Tate 1867, also known from Bajo de Velis (Argentina) and Cerquilho (São Paulo). The flora suggests a Sakmarian age. Plants were found in several horizons associated with marine invertebrates. The paleoflora of Acampamento Velho and Cambai Grande is allochthonous and was transported to the marine environment from nearby emerged areas. All profiles start with paraconglomerates and/or cross-bedded conglomeratic sandstones deposited in a continental environment, that shift abruptly into a fine bedded marine silty-sandstone and siltstones. The is no transition between such facies, which could indicate a very rapid sea ingression on to an irregular landscape. The Budó outcrop is the only one with no trace of Glossopteris flora associated with the marine fossils.
