Tropical hard wood species written at TABLE 1, mainly from East-South Asia, were examined with light microscope, scanning electron microscope and by the ashing method. Woods were maintained at the Laboratory of Wood Science, Kyushu University and used as experimental materials. Results were revealed the fundamental information of wood identification listed up in TABLE 2 and others as follows: 1) Cell inclusives founded by light microscope and electron microscope were different but these were attributable to treatment methods. 2) Ashing method was useful to examine the presence of crystal in cell and to test the chemical reaction which indicates silica or calcium salt. 3) Generally wood contained different shapes of crystal in ray parenchyma and axial parenchyma. Sometimes same tissue contained a few kinds of crystal shape. 4) The crystal presenting in parenchyma was an important key for identification of experimental woods. 5) The species belonging to the DIPTEROCARPACEAE possessed the vertical intercellular canal but in other species, they were absent. 6) Jongkong and Rengas possessed the radial intercellular canal. Rose wood and Jelutong possessed the laticifer. Crystalliferous cell did not present in Jongkong and Jelutong. 7) In Ramin, Durian, Rose Wood, Yellow Meranti and Kapur, crystalliferous cell presented in both tissues of axial parenchyma and ray parenchyma.
