Cytology of Some Sedges from N.W. India

Abstract

Eleven species belonging to four genera, Cyperus, Fimbristylis, Scirpus and Kobresia have been studied. Four species, namely, Cyperus exaltatus (n=48), C. eleusinoides (n=52), Fimbristylis tenera (n=20) and Kobresia royleana (n=40) have been worked out for the first time. New chromosome number has been recorded in Scirpus pauciflorus (n=23+0-3B). Three base numbers x=8, 9 and 13 have been suggested for the genus Kobresia.
