The introduction to plant diversity in Xilong Mountain Natural Reserve on the border between China and Vietnam

Xilong Mountain(22°26′36″～22°46′01″ N,102°32′36″～103°04′50″ E),with the peak 3 074.3 m above sea level,is the highest mountain in southeast Yunnan. The north part of Xilong Mountain belongs to China,and the south one belongs to Vietnam. In 1997,Xilong Mountain was approved as provincial natural reserve. As a new area to botanical study,there are no lists and other botanical literatures for this mountain before. According to the result of two expeditions,179 families,469 genera and 781 species including 23 distributed rare and endangered plants are recognized in the mountains. But the number of species actually distributed in the mountain is higher. 5 vegetation types were found in the mountain,they are:mountane rain forest,monsoon evergreen broad-leaved forest,mountane mossy evergreen broad-leaved forest,mountane top mossy thicket and secondary vegetation. The suggestions on the protection are also proposed.
