An investigation on the resources of wild shade ornamental plants in Guangxi

In order to understand the wild and shade ornamental plant resources and valuable germplasm hidden in Guangxi,the shade and half shade plant resources in Guangxi were studied by the methods of field investigation and specimen collection identification.The results showed that the five basic characteristics of Guangxi wild shade ornamental plants:rich species(162 families,485 genera,and 1 309 species),precious germplasm resources(including 195 species of the valuable and rare plant,and 136 species endemic to Guangxi),diversity of growth soil texture(the calcicole,the acidophile and the intermediate plant),remarkable of the herbaceous ratio(the herb plants account for about 66.1%),and great disparity of wild resources distribution.The six taxa were as following:Pteridophyte(43 families,240 species),Orchidaceae(37 genera,126 species),Liliaceae(21 genera,82species),Gesneriaceae(17 genera,63 species),Begoniaceae(1 genera,43 species) and Araceae(12 genera,30 species).The results would provide a reference for the rational development and utilization of wild shade ornamental plant resources.
