The Curatella americana, popularly called the Lixeira, is a native tree species of Cerrado. In an area that has been degraded to the construction of the Ilha Solteira hydroelectric Selvíria the region - MS, called loan area, there is the occurrence of a natural population of C. Americana, which is gradually recovering the vegetation of the site. Thus, we seek to work with this characterization of the C. americana of individuals in relation to silvicultural variables: height, diameter at breast height, average crown diameter, crown insertion and shape of the trunk and assess the quality of seeds by physical tests (moisture content and weight of 100 seeds) and physiological (electrical conductivity). The study was conducted in Farm Research Education and Extension UNESP and Genetics Laboratory of Populations and Forestry. The statistical program Selegen was used. The time had an average of 8.83 meters, with crown insertion of 1.96 meters. The diameter at breast height was 20.38 cm and the average crown diameter of 7.73 m. The form had a score of 1.77. The average electrical conductivity was 135,69 μS cm-1, whereas the 100 seed weight was 1.18 grams. The characterization of C. americana is important, since this is an essential arboreal species for recovery of degraded areas of the Cerrado
