There are about forty species of Picea found in northern hemisphere. In the present paper, the wood anatomical studies were performed on the eighteen species and one variety: Picea jezoensis CARR., Picea jezoensis CARR. var. hondoensis REHD., Picea Glehni MAST., Picea polita CARR., Picea bicolor MAYR, Picea Koyamai SHIRAS., and Picea Maximowiczii REGEL from Japan, Picea koraiensis NAKAI from Korea, Picea morrisonicola HAYATA from Formosa, Picea Wilsonii MAST. from China, Picea Smithiana BOISS. from Himalaya, Picea rubens SARG., Picea glauca Voss, Picea mariana B. S. P., Picea Engelmannii ENGELM., Picea pungens ENGELM., Picea sitchensis CARR., and Picea Breweriana S. WATS. from North America, and Picea Abies KARST. from Europe. 1. Description of wood anatomical characteristics of each species were performed. 2. Genus Picea was divided into three groups from the wood anatomical point of view, but these three groups have no significant relation with the three sections adopted by A. REHDER. Anyhow, they may perform a significant role on the taxonomy of genus Picea. 3. Particular observation was performed on the main wood anatomical characteristics. Spiral thickenings of longitudinal and ray tracheids, and the presence of crystals. General characteristics of genus Picea which have been described by many from the wood anatomical standpoint should be rewritten. The appearance of spiral thickenings in the longitudinal tracheids of some species has rather close relation with the narrowness of growth rings and the age of the part. 4. Colouration by reduction of flavone derivatives in the wood of some species was found by few species and it could be available for identification of these species. 5. There was a somewhat close relation between the wood anatomical characteristics of the species and their native regions.A. REHDERによると北半球には約40種類の唐檜属樹種が産する。其等のうち中国・ヒマラヤ・台湾・朝鮮・満洲・本邦及び北米・欧洲に分布する18種及び1変種の木材について木材解剖学的性質の比較研究を行つた。現在に至るまで唐檜属木材の解剖学的性質につき多くの報告が出されているが，其等の記載の間に差異が認められたので，其等の再検或いは補足を行い，更に唐檜属木材を解剖学的性質から見た場合，属全体が如何なる性質をもつものとして理解できるかを中心としての研究を行つた。
