| Abstract: | Species of seed plants are rich in Niubeiliang Natural Reserve.There are about 950 species belonging to 105 families and 433 genera,of which there are 66 tropical genera, 311 temperate genera,12 Chinese endemic genera,459 Chinese endemic species and 55 Qinling endemic species. Statistics indicated that the temperate genera played an important role in the flora and that the flora included the unusually high proportion of endemic species. On the basis of analysis on paleobotanical material in Niubeiliang mountain and adjacent areas, the rich and diverse flora have evolved gradually and autochthonally at least since the latest Cretaceous. |
