Fuirena Rottb. is a small genus in the family Cyperaceae comprised of 25 species all over the world. It is represented in India by six species, three of which viz., F. uncinata Kunth, F. ciliaris (L.) Roxb. and F. umbellata Rottb. occur in Eastern India. During the present survey of various members of the family from the state of Orissa, all three species have been collected from Bhubaneswar. The fact that no report of the chromosomes of Fuirena has been available to date aroused interest in determining the chromosome numbers of these three species of the genus. The cytology of a number of species belonging to such genera as Carex, Cyperus, Eleocharis, Fimbristylis and Scirpus has been studied in some detail in recent years. This has revealed that while euploidy and possibly gene mutation have played the main role in the speciation in the genus Fimbristylis (Rath and Patnaik, 1974), aneuploidy seems to be prevalent in genera such as Cyperus (Sanyal, 1972) Carex (Tanaka, 1948) and Scirpus (Sanyal and Sharma, 1972). From this standpoint the study of chromosome numbers in three species of the genus Fuirena was thought to be of value for understanding the evolutionary trend in the genus.
