Rediscovery of Presumably Extinct Species of Aristida in Sa($)over-tildeo Paulo State, Brazil

Two species of Poaceae (Aristidoideae) Aristida ekmaniana Henrard and A. macrophylla Hack. considered "presumably extinct" in the Brazilian state of Sa ($) over tildeo Paulo were rediscovered during fieldwork. We hereby describe the location, ecosystem, and habitat type where the species were found. We suggest these grasses be removed from the list of extinct species and be placed in a category compatible with the current knowledge about their conservation status in the state of Sa ($) over tildeo Paulo.
