Six species of Hylotelephium collected in Asian continent were karyologically studied. The somatic chromosome numbers were 2n=20 in H. tatarinowii, 2n=22 in H. ewersii, 2n=24 in H. viviparum and H. pallescens, 2n=48 in H. telephium, and 2n=46 in H. ussuriense var. ussuriense. The chromosome number of 2n=46 reported here was new to H. ussuriense var. ussuriense. The chromosome numbers of 2n=20 in H. tatarinowii, 2n=22 in H. ewersii, 2n=24 in H. viviparum and H. pallescens, and 2n=48 in H. telephium reported here verified the previous records. Their karyotypes were commonly mono-modal decreasing in length from the largest to the smallest chromosomes and showed similar chromosome sizes and chromosome complements in centromeric positions to each other expecting those of H. telephium had slightly large sized chromosomes.
