  • Karyotypes of 4 species in Lysimachia were investigated.The chromosome mumbers and karyotypes of two species,namely,Lysimachia phyllocephala Hand.-Mazz.(2n=2x=24=2m+6sm+2st+14t)and L.stellarioides Hand.-Mazz.(2n=2x=24=4m+2sm+18t),are reported here for the first time.The other two species,L.clethroides Duby((2n=2x=24=16m+8sm(1SAT))and L.stenosepala Hemsl.(2n=2x=24=10m+12sm+2st),are slightly different from those previously reported.At the same time,we summarized the characteristics of karyotypes in Lysimachia on the basis of the available data for 23 species.
