| Abstract: | Zenia insignis is an endemic species in limestone areas of South China and one of the third grade protected plants in China. Z. insignis, which is heliophilic and deciduous, grows rapidly with a strong resistance to adversity. Z. insignis communities form a spotal phytocoenosis.Z. insignis communities are mainly composed of tropical and subtropical species, largely from Euphorbiaceae, Leguminosae, Rutaceae, Rubiaceae, and so forth. Phanerophytes, the main life form in communities, accounts for 78. 7% of total species. Both mesophyll and microphyll plants amount to 45. 8%, respectively, and leathern leaf plants to 50%. Deciduous species makes up 52% of tree layer. Z. insignis is a declining population in communities that are secondary in limestone areas of low sub-tropical zone. Zenia insignis communities in Guangdong are divided into 3 types: 1) Z. insignis, Adenanthera pavonina, Celtis tetrandra subsp. sinensis forest;2) Z. insignis, Photinia dovedsoniae, Quercus glauca forest, and 3) Z. insignis, C. tetrandra subsp.sinensis, Sterculia lanceolata forest There are many gardening plants and medicinal plants in Z. insignis communities. Z. insignis can be used as a short-term industrial timber tree, fuel tree, forage tree, and as a disposition species interplanted among crops Currently, Z. insignis communities and its parent trees have been severely destroyed. Measures should be taken to protect the precious plant resource. |
