Philodendron bipinnatifidum presents dimorphic roots, where two patterns of aerial roots: fixed and suspended. The root is broken down into two parts: air, ground. This study aims to determine the anatomical and micrometric fibers of the roots of P. bipinnatifidum with the goal of providing subsidies to paper industry. To carry out the measurement of some variable anatomic root portions thereof suspended in air, air-ground and ground-side 10 adults were analyzed, and in each five samples taken from a total of 50 measurements for each variable. Were analyzed: fiber (length, width, thickness and lumen diameter material-decoupled), the total thickness of the root cortex and stele (cross sections). Data were subjected to analysis of variance and the averages compared by Tukey test at 5% probability. Analyzing the statistical data collection is concluded that the fibers of the three portions of the roots examined do not complete the requirements necessary to achieve a quality paper. Although some values are significant portion of the lateral root-underground indicating that they may submit a paper with good strength and stiffness over, would not be economically feasible due to the difficulty of obtaining these roots.Keywords: Dimorphism; fibers; aerial root; root underground.
