Cytogenetical studies of Mentha aquatica L. with 96 chromosomes were carried out by the aid of the interspecific crosses with 4 mint species including 7 strains of the known genome constitutions. It was concluded that the genome constitution of this mint species was RaRaSSJJA5qA5q. In addition, a genealogical tree of the subgenus Menthastrum was tentatively presented on the basis of the results obtained so far.
