This research aims to describe the anatomic characterization of the specie, and to generate results based on the physical and machanical tests carried out at different moisture contents and ageing treatments. In relation with the anatomic characteristics, the presence of 3 defined zones in the cross section is confirmed, as mentioned by Hoffman (1997). The dimensions of the anatomical elements at 3 height levels fall upon the value ranges proposed by the same author. In regard of the physical tests results for moisture content, values reached 84.9% and 15.9% for green and air-dried conditions respectively. The colour defined by Munsell chart was "light shade of yellow" with the 7.5 YR 8/4 code.Finally, linear density was of 65.09 g/m. From mechanical properties, samples of the vegetal material without ageging treatment presented a traction of 535.92 Kg/cm2 , an elongation from initial lenght of 1.4%, a TEA (tensil energy absorption) of 31 138,07 J/m2 , and torsion resistance of 1.065 kgm. In the case of vegetal material samples with ageging treatment, traction was of 584.78 Kg/cm2 , an elongation from initial lenght of 0.97%, a TEA of 15 577.47 J/m2 , and torsion resistance of 0.945 kgm. The results obtained from anatomic and physicalmechanical charaterization allowed to verify the resistance of the vegetal material, adding cuantitave values to the qualitative values from the traditional use native communities give to it as ancestral knowledge. In addition, these results prove its qualities as fiber, and with opportunities for its incorporstion to the non-timber products market.
