Chromosome Numbers in Some North West Indian Species of Polygala

Abstract

Meiotic studies in 11 taxa comprising of 8 species of Polygala (family Polygalaceae) have been carried out. Five species marked* in Table 1 have been investigated for the first time and new chromosome numbers have been made available for the remaining 3 species marked⁺ in the same Table. A normal course of meiosis was characteristic of all the species investigated here. The genus Polygala is proposed to have been evolved from ancient stock of species based on x=7, a base number still preserved in the genus.
