In the Longxi-Hongkou National Nature Reserve,seed plants are estimated at 140 families,790 genera,and 2 183 species,and their geographic distribution types belong to the temperate flora which is characterized by the domination of temperate flora components.The flora is of ancient origin,consisting of many primitive families and genera,and relic species.There are many monotypic and oligotypic genera,and relatively large families and genera with more than 10 species are also common.The distribution of families,as well as genera and species,exhibits evident temperate characteristics.
