Abstract: The objective of this study was to obtain mathematical equations through the leaf dimensions to estimate the area leaf of Cordia myxa L. 392 leaves of plants were collected, located in the municipality of São Mateus, North of the State of Espírito Santo, Brazil, 300 of which were used to adjust the equations and 92 for validation. Of all the leaves, the largest length (L) and maximum width (W) were measured, product of multiplying the length with the width (LW) and the real leaf area (RLA). Models equation first degree linear, quadratic and power were fitted, where RLA was the dependent variable as a function of L, W and LW as an independent variable. All equations were validated according to appropriate criterion. Thus, the power model ELA = 0.84(LW)0.9749, based on the product of multiplication of length with width (LW) is the most suitable for estimating the leaf area of Cordia myxa L.
