The anatomical study deepens the knowledge of G-type conducting cells: 1 It proves the theory of two depositional process for secondary wall (Bierhorst, 1960): the discontinuous cellulose layer is laid down before the continuous lignified layer; the former layer is prone to be broken down, while the latter is highly decay-resistant; 2 It suggests that the cellulose primary and secondary walls of tracheids are not perforated. Instead of longitudinal pits (Li, 1992), the lignified tracheid secondary wall of Hsüa possesses irregular simple perforations; 3 In Hsüa reflexa and Huia gracilis, the perforation casts may represent the thickness of lignified secondary wall; 4 The wall structure of G-type tracheid is diversified. At the genus level, the secondary wall structure differs in the distribution, internal shape and structure of the perforations; 5 Perforations of some G-type tracheids combine the characters of S-type tracheids in their distribution, density and diameter.
