| Abstract: | A floristic study of the Tongledashan Nature Reserve in Yunan County,Guangdong Province,China Was carried out.The seed plants are found to be abundant in this area,represented by 1002 species belonging to 542 genera in 149 families.This flora,composed mainly of phytogeographical elements from the northern border of the Chinese southern subtropical and tropical regions,is characterized by rich floristic components and complex phytogeographical elements.In addition,there are a plenty of rare,endangered,and endemic species in this area,indicating the ancient origin of this flora.Compared with its neighbouring floras,the flora of the Tongledashan Nature Reserve is closely related to those of Longhushan Nature Reserve in Guangxi,and Heishiding Nature Reserve in Guangdong,but only distantly related to that of the Wulingyuan Nature Reserve in Hunan. |
