Under the scanning electron microscope , for the first time we compare and study both the coalified tracheids through chemical maceration and permineralized tracheid lumen casts. This method reveals the microstructures of wall and perforations of G-type tracheids: 1 The lignified layer of secondary wall is composed of uneven material and further divided into S〓, S〓, S〓 layers; with the smooth enclosing wall, the perforation is internally dumbbell-shaped; 2 In Huia gracilis, the enclosing wall of tracheidal perforation contracts and possesses secondary perforations. The perforation has thickened border facing the tracheid lumen.
