 Edit this paragraph classification tree 
 Tie Guan Yin tea tea 
 Is a perennial evergreen woody plants, the main characteristics of China's tea varieties and characteristics of the study, and take care of the existing species classification of habits, we tea varieties in a tree, leaf size and germination sooner or later, the three main characters, divided into three categories level, as the tea tree species classification system. All levels of classification are as follows: the first level classification system known as the "type." Classified as tree traits, mainly in the case of the natural growth of plant height and branching habit may be. Divided into tree-type, small tree type, bush-type. 
 (1) tree type 
 Such tea is a more primitive type. Distribution and the origin of tea in the natural conditions closer to natural areas that China's tropical or subtropical regions. Tall plants, from plant base to the top, have a clear trunk, was always like branches, branch site is high, branches sparse. Large leaves, leaf length variation range of 10-26 cm, most varieties of leaf length of 14 cm. Takes the palisade layer of leaves. 
 (2) small tree type 
 Such an evolution type. Stronger resistance than the Arbor, located in subtropical or tropical tea. Higher plants a large, central trunk from the plant base to clear the plants the upper trunk was not significant. Relatively thin branches, most of the varieties to leaf length 10-14 cm, leaf palisade tissue, mostly two. 
 (3) shrub-type 
 Such is also the type of evolution. Including the most varied, mainly in subtropical tea, the majority of our tea were distributed. Plants low, no trunk, branches from the plant base, branching density, smaller leaves, leaf length variation range. Of 2.2-14 cm, blade length of most varieties of flowering tea 
 10 cm below. 2-3 leaf palisade tissue layer.
