摘要

Somatic chromosome numbers of 15 species belonging to the genus Saussurea collected from the Himalayas and the adjacent regions are reported. The chromosome numbers of 9 species were examined for the first time. Saussurea leontodontoides was found tobe diploid with 2n = 30; S. globosa, S. graminea, S. graminifolia, S. obvallata and S. spicata to be diploid with 2n = 32; S. delavayi, S. forrestii, S. kingii, S. medusa and S. yakla to be diploid with 2n = 34; and S. nishiokae, S. hookeri and S. tridactyla to be diploid with 2n = 36. The chromosome number of S. hieracioides was 2n = 64, which is the first record of a tetraploid with x = 16 in the genus. A new record of Saussurea nishiokae from Tibet (Xizang, China) was confirmed, which was recognizedduring our research.

Forrestii，S. Kingii，S. Medusa和S. Yakla是二倍元，2N = 34; 和S. Nishiokae，S. Hookeri和S.Tridactyla与二倍体为2N = 36.染色体的S. Hieracioides的染色体数为2N = 64，这是在属中具有X = 16的四倍体的第一记录。 确认了来自西藏的索雷西亚·什里科（锡尔西）的新记录，确认了我们的研究。
