Abstract

In Ecuador, the Ilex genus is represented by species of important economic value for local communities. Their ancestral use has allowed them to conserve their ethno-cultural heritage. However, little is known about the physiology and internal structure of these species. Therefore, the goal of this study is to know the features and anatomical wood differences of Ilex guayusa, Ilex weberlingii and Ilex sp. Wood samples were collected from different sites in the provinces of Loja and Zamora Chinchipe in southern Ecuador. The microscopic characteristics of the wood were identified and evaluated in the cross, tangential and radial sections, based on IAWA standards. The results showed that the three species had in common indistinct growth rings boundaries with diffuse-porous, and solitary vessels with outline angular distributed in radial or diagonal patterns. All species showed scalariform perforation plates and opposite pits. The rays for all three species were the same with respect to width, height, and size. However, the only differences in each species were the size of the intervessel pits, and the number of vessels per square millimeter. This demonstrates that microscopic wood characteristics have a high potential for wood identification through anatomical analysis.
