This study aimed to identify newly isolated xanthomonads, using Amplified Fragment Length Polymorphism (AFLP). The results show that, the strains from Lobelia and Isotoma with a similarity coefficient of 84% to each other, but a very far relation to all other Xanthomonas strains. The strains from Lobelia and Isotoma may named Xanthomonas lobeliae spec. nov. The highly virulence strains (HV) isolated from cotton plants can be classified as a new race of Xanthomonas axonopodis pv. malvacearum (race 20). The strains isolated from Catharanthus plants may classified as new pathovar (Xanthomonas axonopodis pv. Catharanthi).
