Geomorphic processes can be studied from the point of view of several disciplines. One of them is the analysis of growth rings. In this particular case the discipline is named Dendrogeomorphology. Based on the principle that the environment conditions the growth of the plant, the changes in the substratum are shown in the growth rings, permitting the interpretation of past geomorphic changes. In relation to the phytodinamics, the identification and count of the growth rings also allow to solve a varied range of problems. Nevertheless, to optimize the results, it is essential to previously learn about the wood structure, particularly growth rings. The present work deals with the wood anatomy of a group of woody species belonging to 21 botanic families. These species are indicators or are closely linked to diverse geo and phytodinamic processes occurring in the Provincia Fitogeografica del Monte. To characterize the growth rings, the type of cell element and their position in the ring was determined. Besides data is given on the probable longevity reached by these plants, as well as definitions about the types of plant indicators.
