Resumo

A new species of Gelasine, named Gelasine aureistaminata, is described and illustrated for the flora of Uruguay and Rio Grande do Sul (Brazil), constituting yet another endemic species for the region of the Campos, of the Grassland Ecosystems of Southeastern South America. Specimens grow in crevices of silicified sandstone rocks, in full sun, associated with small herbs or shrubs, on the tops and steep slopes of hills locally known as <Cerros Chatos>. Gelasine aureistaminata is close related with G. elongata; however, can be distinguished by its narrower basal and caulinar leaves, by its smaller anthers, with whitish-yellow connective and ochre-yellow thecae, and bright-yellow pollen and shorter style with shorter style branches. The species is considered Endangered, following the criteria of IUCN.
