Floristic analysis of the evergreen broad-leaved forest in Minxi,Fujian Province

On the base of 1.6 hm2 cumulative sampling plots investigation of evergreen broad-leaved forest in Minxi,116 families,235 genera and 398 species of vascular plants were recorded. Through areal types analysis of family,genera and species,there were 55 families,142 genera and 231 species belonging to tropical-and-subtropical distribution.
