MARCATI, CARMEN REGINA; ANGYALOSSY-ALFONSO, VERONICA and BENETATI, LUCIMAR. Comparative wood anatomy of Copaifera langsdorffii Desf. (Leguminosae-Caesalpinoideae) in forest and "cerradão". Rev. bras. Bot. [online]. 2001, vol.24, n.3, pp.311-320. ISSN 1806-9959. http://dx.doi.org/10.1590/S0100-84042001000300010.
The present study compares qualitative and quantitative characters of the wood of a tree species (Copaifera langsdorffii Desf.-Leguminosae-Caesalpinoideae) from semideciduous mesophytic forest and "cerradão". Analysis revealed vessels with significantly larger diameter in trees from "cerradão" and intervascular pits being significantly larger in trees from forest. In contrast to the trees from the forest, gelatinous fibers, which have a special layer innermost of the wall, were found in great quantity in trees from "cerradão". Furthermore, the presence of subdivided marginal parenchyma and the absence of axial canals in some of the parenchyma bands are for the first time mentioned for this species.
