Abstract

During floristic surveys in the interior of the state of Rio Grande do Sul (Brazil), populations of Oldenlandia corymbosa L. were found in the municipalities of Santa Maria and Bagé. This study reports the occurrence and naturalization of O. corymbosa in the state of Rio Grande do Sul and the Pampa biome, with a review of its occurrence in Brazilian territory and considerations on its habit and morphology. The collected material was analyzed, photographed, and deposited in the herbaria CNPO and SMDB, resulting in a location map, plates with in vivo photos, scientific illustrations, and an identification key for Oldenlandia in Rio Grande do Sul.
