Abstract
There are 749 species of seed plants belonging to 396 genera and 137 families in Dazhongshan Nature Reserve of Yunnan Province. In this flora,the amount of the cosmopolitan genera is 33,being 8.33% of the total genera. The amount of tropical genera is 206,being 56.75% of the total genera (excluding those cosmopolitan genera,the same below). The amount of temperate genera is 148,being 40.77% of the total genera. The amount of endemic in China genera is 9,being 2.48% of the total genera. The composition of this flora is complicated. The floristic characteristic of seed plants of the region is subtropical in nature,and it is between the tropical flora and temperate flora. So the region is worth of being protected as its complex floristic geographic elements and plants population diversity.
