STUDY ON THE PTERIDOPHYTE OF WULINGYUAN FROM HUNAN PROVICE,CHINA

A preliminary study of the pteridophyte flora of Wulingyuan in Hunan Province, of China is carried out. The floristic compositions, ecological types, distribution and the affinities with its neighbor regions are discussed. In this region, 256 species including varieties and forms of pteridophytes belonging to 86 genera, which are divided into 12 distribution types, in 38 families are recorded. The pteridophyte flora of Wulingyuan is belonging to east and central China region and closely related to southwestern China region.
