| Abstract: | As one of the hottest spots of biodiversity in the world, the Hengduan Mountains region in SW China is attracting more and more attention. Data of chromosome numbers are very important for a better understanding of the origin and evolution of a given flora. Although a large number of species in angiosperms from the Hengduan Mountains region have been cytologically studied, a comprehensive statistic survey of their chromosome numbers is lacking. In this paper, the chromosome numbers of angiosperms in this region are surveyed. It is found that 518 species of 143 genera in 42 families of angiosperms in this region have had chromosome counts. |
