Spermatophyta flora of Gutianshan Nature Reserve in Zhejiang.

There are 155 families, 689 genera, 1?375 species, 8 subspecies, 107 varieties and 10 forma of spermatophyta in Gutianshan Nature Reserve. Among them, gymnosperm has 7 families, 16 genera, 18 species and one varieties; angiosperm has 148 families, 673 genera, 1?367 species, 8 subspecis, 106 varieties and 10 forma; and the cultivated plants are 6 families, 41 genera, 69 species, 4 varieties and one forma.

It is concluded that the flora of Gutianshan Nature Reserve has rich species, and many endemic and rare plants, and that the origin of the flora is from far ancientry, and that the floristic elements are complex and varied, and the relationships with the flora of the South China, South west China, Centre China, Taiwan of China and Japan are very close.
