| Abstract: | Generally speaking,the primary characteristics of flora in the Hengduan Mountainous Region are. there are so many plants, old plants and endemic plants. The geographic components and it's association are complexity. The plant differentiation is very strong.The plant species of Hengduan Mountainous Region not only are about 44.2% of Chinese species and 5.1% of the world species, but also are the present-day distributive centre of many families, genera and species. There are a lot of mo-nospecies genera, few-species genera, endemic genera, prime-types, mid-types and update-types. The evolutions of chains are clear. The supersession phenomena are widespread. There are fifteen distributive categories and about twenty-fourth variable distributive categories. |
