Karyotypes were established in seven Angelica species cultivated in Korea. The somatic chromosome numbers were 2n=2x=22 with the basic number of x=11 in all Angelica plants examined. Their metaphase chromosomes ranged from 3.56 ㎛ to 8.91 ㎛ in length. Distinctive Karyotypes were found in two species, A. tenuissima with all metacentrics, K(2n)=2x=22m, and A. genuflexa with all subtelocentrics, K(2n)=2x=20m+2sm, K(2n)=2x=12m+10sm, K(2n)=2x=16m+6sm, K(2n)=2x=18+4sm and K(2n)=2x=10m+10sm+2st, respectively. Cytological data showed that chromosomal polymorphisms within species were observed in Angelica plants compare to other regions.
