Specific telomeric regions of certain somatic chromosomes in seven accessions of Camellia japonica L. sensu lato were differentially stained by the BSG method. At early somatic prophase, almost all chromosomes in the Camellia accessions studied had C-bands in their telomeric regions. From mid-prophase to mid-metaphase a gradual decrease in C-band number was observed. In order to standardize the data C-bands were recorded at somatic mid-metaphase. Each of the seven accessions of C.japonica L. sensu lato studied here had a characteristic and recognizable C-banded karyotype. In most cases in these accessions the C-bands were found in the telometric regions of the chromosome arms, and C-banded karyotype maintained some heteromorphism. Of those studied here, Cal7tellia japonica L. subsp. lusticana (Honda) Kitamura was quite different from the others.
