Abstract

There are 128 families,605 genera and 1 231 species (infraspeci fic taxa were not inclued) of seed plants in Tianyuhe River-Valley in Qinling Mountains.The floristic analysis shows that 70.96% (386 genera) of total genera are temperate composition,21.13% (115 genera) are tropic composition,4.41% (24 genera) are Mediterranean and Central Asia composition,and 3.5% (19 genera) are endemic to China in this drainage basin.Therefore the floristic character of this drainage basin is mainly temperate composition.
