MARCHIORI, José Newton Cardoso and MUNIZ, Graciela Bolzon de. Anatomy of the secondary xylem of Mimosa trachycarpa Benth. Cienc. Rural [online]. 1997, vol.27, n.2, pp. 223-228. ISSN 0103-8478. http://dx.doi.org/10.1590/S0103-84781997000200009.
The wood anatomy of Mimosa trachycarpa Benth. is described. Photomicrographs as well as quantitative and stereological data of its minute structure were furnished. Very fine rays, paratracheal parenchyma, libriform and not septated fibres, vestured pits and pores in clusters, tending to a diagonal pattern, were found. The wood anatomy was checked with literature of the Leguminosae family and genus Mimosa, considering its phylogenetical, taxonomical and ecological aspects.
