metadata.revistascielo.dc.description: This study determined the anatomical, chemical and physics characteristics of candeia wood (Eremanthus erythropappus (DC.) Macleish). Five trees were collected from Carrancas-MG, and disks were obtained at the breast high (DBH) to sample preparation. The description and mensuration were performed at the principal anatomical structures (fibers, vessel and radial parenchyma). For chemical analysis, the extractives content, hollocelulose, lignin and inorganic components were determined. The physical properties included the basic specific gravity, specific gravity at 12% moisture content as well as tangential, radial and volumetric shrinkage and coefficients of shrinkage and anisotropy. The main results found for macroscopic characteristics were: awkward odor due to presence of oil-resin; reversal grain and hardness to the cut; microscopical characteristics: scarce parenchyma axial and radial very thin, elements of vases with numerous and very small pits, short plates of simple perforation, libriforms fibers with thick cellular wall and presence of oil cells in the ray. Chemical composition: 20.89% total extractives; 50.52% holocelulose; 28.59% lignin and 0.39% of inorganic constituents. The specific gravity at 12% was of 0.98 g/cm3 and the basic specific gravity of 0.79 g/cm3. The anisotropy coefficient was 1.91 and the coefficient of volumetric retratibility was 0.28%.
