Abstract
Chromosome numbers were determined for eight species of Piper namely P. argyrophyllum Miq., P. attenuatum Ham., P. galeatum C. DC, P. longum Linn., P. nigrum Linn., P. trichostachyon C. DC, P. hookeri Miq., and P. mullesua Ham. The first six species showed a chromosome number of 2n = 52 and the last two, 2n = 104 each. A glance at the chromosome numbers of Piper spp. so far recorded from India, shows that mostly multiples of 12 chromosomes have been reported from the North India and multiples of 13 from the South India. It may be assumed that the species from these two centres of distribution probably had different evolutionary pathway starting from basic numbers of 6 and 7.
