Two new species of Sporobolus R. Br. are described for Brazil, S. metallicolus and S. multiramosus, the first one distributed from Central-Western Brazil to paraná State, the second only known so far for Northern Brazil (Pará State). Both species are closely related to S. ciliatus Presl due to their small size and their contracted inflorescence. This relationship is discussed in the present work.
