This study examined the anatomical characteristics of indented growth rings in Lebanon cedar. In the indented pattern of growth rings, the alignment and shape of tracheids and rays were found to be irregular, and distinctive trabeculae were identified in tracheids. Multiseriate parenchymatic rays occur in addition to uniseriate and biseriate ones. In the indented pattern the average tracheid length is shorter, whereas the lumen diameter and double-wall thickness are wider than those of unindented ones. The average maximum ray height is greater than that of normal wood. The average number of tracheids per mm2 differs only in latewood.
Key words: Cedrus libani, indented rings, tracheids, traumatic tissue.
