Abstract
Five types of chromosome pairs were noted in Crotalaria saltiana and C. verrucosa the number of pair or pairs of chromosomes included in each type varied in the two species. Length of the chromosome in C. verrucosa was relatively longer than C. saltiana. Both the species have only one pair of secondary constricted chromosomes. In C. saltiana out of the 9 constrictions 4 are median, 4 are submedian and one subterminal in position whereas in C. verrucosa 3 median, 4 submedian and 2 subterminal were in position. All these relevant data suggest that the two species stand intermediate between primitive and advance stages in evolution. Diploid chromosome number in C. ferruginea (2 n = 16) is a new record
