| Abstract: | Laojunshan one of the highest peak in Funiu Mountain range in west Henan hasa total of 1534 species,representing 601 genera and 131 families. After a thorough andcareful floristic analyses of the families,genera and species in the present flora and compar-ison of the related regions,we came to the following conclusions:1,The flora was originat-ed from the ancient tropical elements and had temperate characteristics at present;2,Theorigin of the mountain flora was ancient and the flora was remarkably derivative to a cer-tain extent;3,This flora belonged to the North China flora region of the Sino-Japan forestsubkingdom;4,The geographical elements were very complex and varied,and the flora wasrelated extensively to most parts of the world;5,Laojunshan was rather rich in spermato-phyte and had more species endemic to Henan;6.The flora had a transitional characterfrom south warm temperate to north subtropics and there were lots of mixture ingredientsfrom west to east. |
