| Abstract: | Itwas known that there were 616 species of seed p lants in Kuocangshan Nature Reserve, which belongedto 336 genera of 115 families. Among them, there were 8 species of Gymnospermae belonging to 7 genera of 5families, 608 species of Angiospermae belonging to 329 genera of 110 families. There were 15 families whichconsisted of more than 10 species. 323 genera were monotyp ic or oligotyp ic genera. The geographical floristicalcomponents in Kuocangshan Nature Reserve were very comp lex and these species p layed important roles in seedp lant flora. On the distribution type of families, Pantrop ic type was the dominant ( 36 families) , followed byCosmopolitan type (34 families) , accounting for 31. 30% and 29. 57% of the total families respectively. On thedistribution types of genera and species, Pantrop ic distribution type was the dominant, followed by north temperatedistribution type, which showed the characteristic of transitionality. Endemic characteristics of family, genus andspecieswere not obvious. |
