The anatomy of some important Taiwan woods Hwang, Shao-Kang


A study was made of single wood samples from 35 species (27 genera and 16 families) of important Taiwan timbers. Results have been compared with information published by Kanehira in 1921 (30) and others (31, 44). The anatomy of these woods is described in detail. A key based on microscopic features is included for identification. Descriptions follow standard terms of the International Association of Wood Anatomists Two of the coniferous species, Pinus armandi Franch. and Chamaecyparis formosensis Matsum., and nine hardwood species Carpinus kawakamii Hay., Quercus gilva B1., Quercus longinux Hay., Cinnamomum camphora Nees., Cinnamomum randaiensis Hay., Lagerstroemia subcostata Koehne., Gordonia axillaris (Don.) Szysz., Trochodendron aralioides S. et Z., and Trema orientalis B1. had features similar to those reported (30, 31, 44). Seven hardwood species, Alnus formosana (Burkill.) Makino., Quercus stenophylloides Hay., Engelhardtia formosana Hay., Beilschmiedia erythrophloia Hay., Cinnamomum micranthum Hay., Zelkova formosana Hay., and Tectona grandis Linn, f. showed different anatomical features from those recorded by Kanehira (30) and Kribs (31). No previous description of wood anatomy has been found for seventeen species including Tsuga chinensis (French.) Pritz., Cunninghamia konishii Hay., Libocedrus formosana Hay., Chamaecyparis taiwanensis Masam. et Suzuk., Scheffera octophylla (Lour.) Harms., Castanopsis longicaudata Hay., Castanopsis stipitata Hay., Lithocarpus amygdalifolia Hay., Actinodaphne nantoensis Hay., Machilus arisanensis Hay., Machilus pseudolongifolia Hay., Machilus zuihoensis Hay., Cassia siamia Lam., Michelia formosana Mas., lllicium leucanthum Hay., Schima superba Gard. et Champ, and Ternstroemia gymnanthera Spr. All species treated in this study are described in more detail than occurs in past records. Mass grouping of longitudinal parenchyma appears as a normal feature of Cunninghamia konishii Hay. This type of parenchyma distribution could be a taxonomic feature of Cunninghamia not previously described in the literature.
