A Preliminary Study on the Flora of Seed Plants of Vegetation in Tongboshan Nature Reserve of Jiangxi Province

The composition,areal-types and floristic characteristics of seed plants in Tongboshan Nature Reserve were statistically analysed.The results showed that there were 1 328 species of seed plants belonging to 610 genera in 156 families.Among them,there were 13 species of Gymnospermae belonging to 10 genera of 5 families,1 315 species of Angiospermae belonging to 600 genera of 151 families.There were 16 families which consist of more than 20 species,and 554 genera were monotypic or oligotypic genera.The geographical floristical components in Tongboshan Nature Reserve were very complex and these species play important roles in seed plant flora.On the distribution type of families,Pantropic type was the dominant(68 families),followed by Cosmopolitan type(29 families);on the distribution types of genera and species,Pantropic distribution type was the dominant followed by North Temperate distribution type,which obviously showed the characteristics of transitionality of the flora.
