【Abstract】 Huashui Mountain of Yingde City, Guangdong Province, is situated at long. 113°40’ E. by lat. 24°22’. Recent investigation on vascular plant resources and flora shows that the flora has a total species (including varieties) of 1 273 belonging to 199 families and 656 genera. The fern of 128 species has a high rate in the flora and indicates that the flora is an old one. Plant resources are plentiful in this area. The characterestic families are Fagaceae, Theaceae, Lauraceae, Symplocaceae, Aquifoliaceae, Moraceae, Myrsinaceae, etc. all of which are the basic elements of Cathayasian flora. Phytogeographically, the pan_tropical and Asian tropical genera are common, meanwhile the tropical elements and temperal elements also appear in this area, but most of them include only a few species. It’s possible to believe that this area is the north border of the tropical plant and the south border of the temperal plant. The nature of old origin, the special transition from south subtropical to center subtropical, and species diversity of plant are typical in Huashui Mountain flora.更多还原
