Taxonomy of species in Cyperus section Arenarii was investigated as a part of ongoing phylogenetic study. Morphological characters revealed that seven new species need to be described, three annuals, Cyperus ephemerus, C. forskalianus and C. sahelii, and four perennials, C. algeriensis, C. gubanii, C. mauretaniensis and C. pseuderemicus. Their relationships with closely related taxa are discussed and their distribution is presented. Annuals are not known previously in the section Arenarii. A new combination, C. subtilis (Kuk.) Kukkonen & Vare is made. The name is typified.
