Chromosome counts were carried out in root tip cells of Nepenthes khasiana (Nepenthaceae), a threatened insectivorous plant of Northeast India. N. khasiana has become threatened in its natural habitat due to overexploitation for its medicinal uses as well as its ornamental importance. Plantlets of Nepenthes khasiana collected from Jarain, Meghalaya were cytologically analyzed. All the root tip cells analyzed showed the chromosomenumber of 2n=80 without any variations. Karyomorphological studies were not plausible in this species due to the relatively small size of the chromosomes.
