Abstract
The plants of the Wanda Mountain area were investigated between 2009 to 2013. The results show that Wanda Mountain has 95 families of seed plants distributed in 334 genera and 705 species. A geographical component analysis shows that in addition to a small number of cosmopolitan species, cold, temperate and tropical species account for 14.9%, 77.3% and 4.4% of the total species, respectively, indicating that the flora of the Wanda Mountains exhibits a significant temperate nature and includes a small number of tropical components and certain cold components. In addition, the Wanda Mountains show a remarkable level of endemism and are geographically related to other regions in East Asia, particularly Japan. Furthermore, the Wanda Mountains present a complicated species composition, with a total of 14 distribution patterns and 10 variants. The coefficient of similarity between the flora of the Wanda Mountain area and the flora of the Changbai Mountain area is 43.1%, and the coefficient of similarity between the flora of the Wanda Mountain area and the flora of the Lesser Xingan Mountain area is 49.2%, indicating that the plants of the Wanda Mountain area are more common to those of the Lesser Xingan Mountain area.
