The chromosome numbers of the five species and one variety of Hosta (H. plantaginea, H. tokudama, H. kikutii, H. crisupla, H. longipes and H. kikutii var. yakusimensis) were 2n=60. The 60 chromosomes were classifiable into 30pairs. The karyotypes of the above species were as follows: The 30pairs of one species and one variety (H. crisupla and H. kikutii var. yakusimensis) could be classified into four pairs of large chromosomes, two pairs of medium ones, and 24 pairs of small ones. The karyotypes of the other four species were as follows: In three of these species (H. plantaginea, H. tokudama and H. kikutii), the chromosomes could be classified into four pairs of large chromosomes, three pairs of medium ones, and 23 pairs of small ones. In the remaining one species (H. longipes), there were four pairs of large chromosomes, four pairs of medium ones and 22 pairs of small ones.
H. kikutii and H. kikutii var. yakusimensis seem, judging from their karyotypes, to have both derived from H. montana.
