Abstract
Chromosome numbers in 126 accessions representing 58 taxa belonging to 27 genera of Panicoideae from Pakistan are reported. Chromosome numbe rs of three species viz. Panicum atrosanguineum (n = 18), Pennisetum l anatum (n = 18), and Elionurus royleanus (n = 10) are new determinatio ns. New cytotypes are reported for Isachne himalaica (tetraploid) and Setaria intermedia (tetraploid). Chromosomal counts for 30 other speci es are new to the flora of Pakistan. More than two-thirds of the speci es investigated were found to be polyploid in nature.
