Abstract: There are 1009 species of vascular plants which belongs to 337 genera in 96 families,including Pteridophytes(41 species,30 genera and 22 families)and spermatophytes(968 species,307 genera and 74 families)in wetland of Hubei province.This flora is mainly composed of herbage and the phenomena of preponderant families and genera are obviously.The distribution area types of this flora were abundant.For species level,there were 15 distribution area types and 5 sub-types,for genus level,there were 13 distribution area types and 12 sub-types,and for family level,there were 8 distribution area types and 2 sub-types.This is proved that the flora with complicated geographic distribution and extensive connection with other flora.Comparing with tropical elements,the temperate elements occupy only slightly predominance,which reflect the character of the flora transferring from tropical to temperate.The cosmopolitan components are constructive and dominant elements in the flora but the endemic genera and species are scarcity which reflects the intrazonal nature of the flora.
