The present study indicates the abundant occurrence of two types of fibers (bark and xylem fibers) in the stem tissues of the evergreen circum‐Mediterranean shrub T. hirsuta. The bark fibers have cellulosic walls, and are much longer, and narrower in diameter and lumen. The means of these variables are 3329, 12.6, and 6.9 microns respectively. On the other hand, xylem fibers have lignified walls. The means of their length, diameter, and lumen are 824, 13.9, and 7.8 microns respectively. The frequency distribution of the length of both types of fibers are presented. The fiber dimensions of this plant are comparable to those of many soft and hardwoods, and more suitable, from the papermaking point of view, than those of bagasse and rice straw: the main local materials for the production of paper in Egypt.
