The chromosome number of 18 species coming under 6 genera of Cyperaceae from South India has been studied. Chromosome numbers determined in the present study range from 2n=16 to 2n=96.
Chromosome numbers determined in the present study and those reported previously in the family reveal the presence of a continuous series of basic numbers between n=8 to n=48. The primary basic number of the family may be n=8 and from this other basic numbers should have originated by means of aneuploidy and euploidy. Along with these karyotype alterations of chromosomes also play important role in evolution.
Karyotypes in the family also show differences in absolute chromosome size indicating changes in nuclear DNA in evolution.
