Further Studies on the Cytology of Central and East Himalayan Grasses

Abstract

Cytological investigations on 20 taxa belonging to 13 species of grasses have been carried out from the hills of Darjeeling (E. Himalayas). Three species, Colpodium nutans (n=7), Tripogon jacquemontii (n=10) and Phyllostachys kumasaca (2n=48) were investigated for the first time. A putative hybrid O. compositus×O. burmannii was discovered from the area. It showed highly aberrant meiosis. Agrostis stolonifera has been found to possess 3B-chromosomes.
