Based on field studies and reserve scientific literatures, this study has statistics and comparatively intensive analysis on seed plants of Wugongshan region. Results showed: (1) There are 2 079 species including 814 genera in 166 families, accounting for 72.81%, 61.11% and 50.46% in family, genera, and species of the seed plants of Jiangxi Province, respectively. Among them, there were 7 families, 15 genera and 19 species of Gymnosperms, accounting for 77.78%, 65.21% and 54.28% of Gymnosperms in Jiangxi Province respectively. (2) There are 12 areatypes of familie in the region, the flora in families displayed tropical feature, but the temperate feature is also obvious, for 57.96%(including 70 families) of tropical elements and 38.65% (including 46 families) of temperate elements. There are 14 areatypes of genera in the region. The tropical elements have a slight advantage and temperate elements is further developments, for 49.40% (including 368 genrea) of tropical elements and 47.53% (including 354 genera) of temperate elements. There are 14 areatypes of species in the region. The temperate elements have a slight advantage, for 31.04% (including 626 species) of tropical elements and 32.87% (including 663 genera) of temperate elements. From the plant distribution in this region, the flora show a tropical transition to the temperate characteristics, and the components of tropical blend with temperate. (3) The flora possesses lots of monotypic and oligotypic genera, with an ancient origin. There are 414 genrea of monotypic genera, accounting for 50.86% of the total. There are 728 species, 23 genera, 4 families endemic to China. (4) Compared with 15 other regions, and the results showed that the seed plants in Wugongshan region are abundant. Cluster analysis show that the flora of Wugongshan region has the most close relationship with Huangshan Mountain, Lushan Mountain, Wuyi Mountain and Jinggang Mountain, and the most distant from the Qinling Mountain, Xishuangbanna and Gaoligong Mountains.
