Abstract: Xiaowutai Mountains, located in the northwest of Hebei Province, is situated between 39°50'~40°07'N latitude and 114°47'~115°30'E longitude.There are 1 148 species of seed plants, belongs to 467 genera and 97 families in Xiaowutai Mountains.The areal-types of the genera are abundant.Analysis of the floristic elements shows that the temperate distribution elements, having 280 genera and accounting for 69.31% in total genera (excluding cosmopolitan), hold a dominant position.Moreover the floristic geographic compositions of seed plants of Xiaowutai Mountains and some mountains, China were studied by using the analysis of similarity coefficient of genus respectively, and the results indicated that there is higher homogeneity and close relationship between the floristic elements of Xiaowutai Mountains and Dongling Mountains, Wuling Mountains, and some similarity with Guandi Mountains and Taiyue Mountains, However, there is less similarity between that of Xiaowutai Mountains and Changbai Mountains, Tai Mountains, Funiu Mountains, Shennongjia Mountains.

Key words: Xiaowutai Mountains, seed plants, flora, similarity coefficient
