STUDIES ON THE SHAPE AND DISTRIBUTION OF THE WILD TEA-TREE GROUPS

1. The wild "tea-tree, groups" in this paper is the original wild tea-trees that can be drunk and distribute depending’ on. natural spreading and growing in original forest.2. According to the properties of shapes and characteristics of ecology, wild tea-trees can essentially be grouped into four groups."Three River", "East of Yunan-West of Guanxi", "South of Sichuan-North of Guizhou" and "Nanjing". The tree statures of the first two groups are taller and larger, their leaves are larger and thinner, while the tree types of the othe two groups are shorter, their leaves are thicker 3. It is recognized that the originating center region of tea-tree is the center (98°-108°E, 22°-29°N) of all groups of the wild tea-tree.
