Abstract: The distribution patterns and their interrelations of branches, flowers and fruits in the canopy of wild Camellia indochinensis var. tunghinensis were investigated with the stratified survey method. The results showed that Camellia indochinensis var. tunghinensis grew slowly, it bloomed when its base diameter got 1.5 cm; the branch composition of Camellia indochinensis var. tunghinensis was complex, its multi-branched series was up to 6 levels, 3~6 levels were increasing from the top canopy to the bottom, and the 5 and 6 levels were 4.06% and 0.38%, respectively; overall, the third-level branch was the most in the canopy, accounting for 38.37% of total fruit branch. The number of nutrition branches was more than the budding ones, and the latter was descending from middle top to bottom along the canopy, while the former was different; the branching angle was small, 70°~90° accounted for 11.56% of the total; there were many flower buds, but the rate of fallen ones was high. The flowers distributed on 2~4 leaf positions in 1~3-year-old branches; fruits mostly distributed in the middle and bottom of canopy, and the peripheral was more than the center. The number of branches, flower buds and fruits in different canopy layers was closely correlated.
