The tall-palm is a woody tree which one found in islets of stand in the natural vegetation in the localities of Ngam, Goundi, Kimri, Houndouma in Chad. Its trunk, being able to exceed 15m height, is used in the frames of the traditional and semi-modern housings. However, little of scientific and technical works have been performed on this wood to allow its rational use. This paper focuses on the determination of its anatomic and chemical features for the understanding of the physical and mechanic behavior of this wood. Anatomical analyses allowed us to quantify by mean 124 fibers per cm2 in the duramen and 77 fibers per cm2 in the sapwood. Chemical analyses performed equally allowed to determine a mean rate of: - 63.21 % of cellulose in the duramen and 61.89 % in the sapwood; - 9.60 % of hemicelluloses in the duramen and 11.32% % in the sapwood; - 19.36% of lignin in the duramen and 19.68% in the sapwood.
