Abstract: There are 71 families,304 genera and 728 species in spermatophytic flora of Mila Mountains.Among them there are 3 families,7 genera and 12 species of Gymnospermae.The flora is complex in geographical elements,and shows endemism evidently.On the analysis with areatypes of family,genus and species,the component of this flora is composed from temperate members basically(43.66% family,84.62% genus and 58.72% species).The flora shows typical temperate character,and youthful characters.According to the degree of abundance in species and some geographical features,this region can be floristically divided into 2 subregions:E Slope Mila Mt.Subregions and W Slope Mila Mt.Subregions.The comparison of floristic characteristics of Mila Mts.with contiguous of Sergyila Mts.and Medog Nature Reserve,the floristic relationship between the flora of Mila Mts.and that of Sergyila Mts.is more close than that between the flora of Mila Mts.and Medog Nature Reserve.
