The purpose of this research is to characterize the anatomical structure and physical-mechanical properties of the aerial roots of Heteropsis flexuosa "tamshi wire" (Araceae) exposed to different conditions of humidity and aging treatments. The characteristics of the anatomical elements of the roots confirm the presence of three visibly differentiated zones, observing in the non-peripheral stela a large number of compressed fibers that provide resistance to the roots. Regarding the physical tests, the moisture content of the roots in green condition was 84.9% and in dry condition to the air it was of 15.9%; the linear density was 65.09 g / m. The values of the mechanical properties of the roots without aging were lower than those obtained with aging; the elongation was 1.4% and 0.97% compared to the initial length, the TEA (tensile energy absorption) was 31138.07 J / m2 and 15577.47 J / m2, and the torsional strength of 1.065 kg / my 0.945 kg / m, respectively. Roots with aging showed tensile behavior of 584.78 Kg / cm2, and without aging of 535.92 Kg / cm2. The results obtained both in the anatomical and physical-mechanical characterization have allowed to confirm the resistance of the aerial roots, endorsing the knowledge of the inhabitants of the rural communities who use the fibers in a traditional and ancestral way. The quality of the plant fiber of Heteropsis flexuosa presents possibilities to compete in the market with other similar vegetable fibers.
