One hundred and thirty four families, 578 genera and 1197 species are recorded in this area. According to the information of historical geology and natural conditions, the composition of seed plant flora and the areal-types of genera were analyzed. The results showed that its origin was rather ancient and its geographical compositions were complicated. There were many species of rare and endangered plants, e.g. Taxus chinensis var. mairei, Bretschneidera sinensis, Emmenopterys henryi, Fokienia hodginsii, Torreya grandis, Phoebe bournei, Ormosia henryi, and so on.
