Resumen
In Ecuador there are large areas of native forest and for some years large areas of forest have been
indiscriminately exploited in the Esmeraldas province. This research proposes: To describe
organoleptically and anatomically the wood of five forest species, from the Tabiazo parish,
Esmeraldas canton, Esmeraldas province; to generate extraordinary content on the macro and
microscopic characteristics of different forest species. The ESPOCH herbarium was used to identify
dendrologically the five forest species under study. To describe the anatomical characteristics of the
five species, the samples of the wood of the five species were exposed to a softening process, then
in the microtome, histological cuts were made, and the sheets were placed in the staining (combined
Safranina / Astrablue, safranine and astrabluc), to describe the organoleptic characteristics were
appreciated using the senses. To determine which staining allows a better observation of the
anatomical characteristics, Motic Images 2.00 was used. In the identification none of the species
belong to the same family. In the organoleptic and anatomical characteristics it was demonstrated
that the species are different and all the species presented solitary and multiple pores of two and
three and one of them presented pores of four. The best staining in this study was combined since
structures with better quality are observed.
