--- Fiber extracted from the leaf of Astrocaryum chambira (Arecaceae) is characterized from anatomical, physical and chemical properties. The results are compared with those obtained from leaf fibers of three other species of the genus (Astrocaryum jauari, A. standleyanum and A. perangustatum). The biological material consisting of fibers, open and unopened leaves are collected in the field, the techniques used were macerated leaf, freehand cross sections and microtome cuts for light microscopy and ultrathin for transmission electron microscopy. The chambira fiber is composed of cellulosic non-vascular fibers, which are extracted together with the epidermis and hypodermis adaxial of the leaf. The non-vascular fibers have a noticeable length. The ultrastructure of cell wall non vascular fiber consists in three sub layers, being the intermediate layer the thickest. The chambira fiber has high cellulose content and low lignin content; it develops a high tensile strength. The leaf fibers of species studied are long and wider in mature leaves than in non-opened leaves. Astrocaryum jauari, A. standleyanum and A. perangustatum differ from A. chambira in the size of the leaf fibers and of the nonvascular fibrous strands. Astrocaryum chambira fiber can be classified as a soft fiber, similar in length and resistance to commercial fibers. Key words: Astrocaryum, Arecaceae, cellulosic fiber, chambira fiber, non vascular fiber.
