The present paper reports the chromosome numbers and karyotypes of nine species and one variety of Heracleum in the Hengduan Mountains of China. Among them the somatic chromosome number and karyotypes of seven species and one variety are reported for the first time. The chromosome number of all the species is 2n=2x=22 except H. millefolium var. longibobum, which has both 2n=22 and 2n=24. The karyotypes of the nine species and one variety of Heracleum consist of metacentric and submetacentric chromosomes
