Cytological characteristics of Abeliophyllum distichum (Oleaceae), endemic to Korea, was examined. Somatic chromosome numbers was 2n=28 which corresponds to diploid based on x=14. Chromosome length was varied continuously from 1.00㎛ to 2.03㎛. Karyotype of Abeliophyllum distichum was investigated in this study for the first time. The cytological characteristics including basic chromosome number, continuous variation of chromosome length, diploid and karyotype were similar to those of the genus Forsythia, which indicated the close relationship between Abeliophyllum and Forsythia, and consequently the two genera seemed to be included to same tribe.
