        space between overlapping bracts < 1mm
        
        anther wide and anther length < 0.5 mm
        
        stigma length < 2 mm
        
        size of anthers and stigmas are less than half of maturity flower
      - st2
        
        space = 1~3 mm
        
        anther 0.5~1 mm
        
        stigma 2~4 mm
        
        anthers and stigma are same size of maturity flower

        anthesis
        
        staminate flowers: anther dehisce, and pollen exposed
        
        pistillate flowers: stigma split and surface wet
  - - - large number of hemipteran larvae was found on both staminate and pistillate inflorescences at wall flower stages suggests that the gemipterans use the inflorescences as breeding-site before and during flower anthsesis.
    - - orius atratus
        
        density doesn't different from staminate and pistillate tree
        
        females is significantly hither on pistillate tree
        
        9.3% collected from pistillinate tree carried pollen load
      - decomioides schneirlas
        
        didn't find carrying pollen load from pistillate tree
