Cytological investigations of 46 taxa belonging to 35 species and 13 genera of the tribe Paniceae (Gramineae ) have been carried out from the hills of Darjeeling and Nainital. Of these 2 species, Panicum khasianum (n=18) and Setaria forbesiana (n=18) have been worked out for the first time. New chromosome numbers are made available for another 10 species, Digitaria ciliaris (n=9), D. cruciata (n=36), D. ternata (n=18), D. violascens (n=9), Oplismenus burmanii (n=18), O. compositus (n=27, 27+6-13B), Paspalum scrobiculatum (n=40), Pennisetum orientale (2n=45), P. triflorum (n=9) and Setaria paniculifera (n=27).
Cytological races have been investigated for Barchiaria ramosa n=16, 18; Digitaria ciliaris n=9, 27; D. cruciata n=18, 36; D. violascens n=9, 18; Oplismenus compositus n=27, 27+6-13B and Pennisetum orientale n=9, 2n=45.
The base number x=9 is suggested for the tribe Paniceae.
