摘要

The anatomical structures of the wood were used as a tool to minimize possible errors in the recognition of commercial species from the Amazon. The aim was to evaluate the diagnostic anatomical characteristics of wood to distinguish species associated with the common names “Angelim-pedra”, “Cumaru-amarelo”, “Currupixá”, “Garapeira”, “Ipê-amarelo”, “Ipê-roxo”, “Itaúba”, “Maçaranduba”, “Maparajuba”, “Muiracatiara”, and “Tatajuba”. The consistency of the identification made in the inventory of 11 common names was assessed using wood samples collected from five trees for each name in a forest management unit in the Amazon. Six common names had the correct botanical identification and five were incorrect. For the common name “Angelim-pedra”, the species Hymenolobium petraeum and H. excelsum were recognized among the samples analyzed, and have similar arrangements of anatomical structures, which allowed the identification to be determined with certainty only at the genus level. For the “Currupixá”, the species Micropholis guyanensis, M. melinoniana, and M. casiquiarensis were recognized, and only for M. casiquiarensis were anatomical structures arranged in such a way as to differentiate it from the others. The name “Muiracatiara” included the species Astronium lecointei and A. graveolens, which have well-diagnosed anatomical differences, allowing the species to be determined correctly. For the group “Ipê-roxo” and “Ipê-amarelo”, four species of the genus Handroanthus were recognized, which were differentiated by the anatomy of the wood through the type of axial parenchyma. This shows that there is a weakness in identifying species in areas under forest management and that wood anatomy is a tool for reducing errors.
