Abstract

Karyotype change of Lysimachia mauritiana was cytologically analyzed in 76 individuals collected in the northern and middle parts of the Ryukyu Archipelago in Kagoshima Prefecture, Japan. Sixteen cytotypes were recognized in the areas. At least, four long median- and six terminal-centromeric chromosomes were included in the chromosome complements of the individuals observed. Remarkable choromosomal polymorphism or karyotype variation was shown in the Ryukyu Archipelago, especially the Amami group.
