The chromosomes of 4 species of Galactia (Fabaceae) have been studied and all of them have 2n=20. The chromosome numbers for Galactia marginalis Benth. (2n=2x=20), G. boavista (Vell.)Burkart (n=x=1 O) and G. benthamiana Micheli (2n=2x=20) are presented for the first time. The karyotypes of G. striata (Jacq.) Urb. var. striata (20m) and G. benthamiana (14m + 6sm) aredescribed. Both species can be distinguished by their karyotypic formula.
