Jatropha curcas L., is popularly known as physic nut, is native to Brazil and it belongs to the Euphorbiaceae family, whose seed is extracted an oil that might be used in the production of biodiesel. It is one of the only oil varieties that do not directly compete with food agriculture. Despite the great potential of Jatropha, several factors must be addressed for full domestication of the species. In this sense, studies aimed at establishing methodologies and morphoanatomical parameters which allow to detect whether or not differences between populations are essential. The objective of this study make a foliar morphometric analysis of three populations of J. curcas L. from the farm located in the Municipality of Piracuruca, Piauí, Carnauba. Geometric morphometry of anatomical landmarks was used. The study was conducted from March 2013 to June 2014. 30 leaves of each population were collected and selected eight anatomical landmarks. The principal component analysis showed that the first three principal components were significant using the "broken stick" model, comprising 60.5% of the total variance. MANOVA only showed significant difference between two of the three pairs of populations, when performed without the alignment of Procrustes. There are no significant differences between populations.
