Abstract

Chromosome characters of three indigenous medicinal plants of high repute were studied. Their karyotypes were commonly mono-modal, decreasing in length from the longest to the shortest chromosomes. The chromosome complement in centromeric positions was 6sm+34M+24m for Bacopa monnieri (L.) Wettst. (2n = 64), 2m.st+12M+6sm+2m for Tylophora indica (Burm.f.) Merrill (2n = 22) and 2m.st+4m.sm+4M+18m+20sm for Withania somnifera (L.) Dunal (2n = 48).
