Chromosome number of 45 species belonging to 12 different genera of Cyperaceae were determined through meiotic and pollen mitotic analyses. Of these 14 cases were proved to be new reports. While larger number of species were studied from Cyperus and Fimbristylis only one species from each of the genera Bulbostylis, Courtoisia, Lipocarpha and Rhynchospora had been investigated. In the light of these cytological findings the taxonomic problems in different groups of species in the family have been discussed.
