| description | The wood anatomy of Oecopetalum mexicanum Greenm. & C. H. Thomps. is described for the first time. This species grows in the forest and coffee ecosystem of the sierra de Misantla, Veracruz, Mexico. In order to recommend possible uses, mechanical properties essays of different types were carried out. These were: bending, like stress at proportional limit, unit work to proportional limit, modulus of elasticity, modulus of rupture, and unit work to maximum load in bending; parallel compression to grain, like maximum strength, stress at proportional limit and modulus of elasticity. All these essays were performed in green wood condition. For each sample, specific gravity was obtained. Vessel diameter, density and distribution, and estimation of abundance and distribution of axial and radial parenchyma were measured from permanent slides. Fiber and vessel elements length, as well as cell contents, were determined from macerated wood samples. Anatomical descriptions were made according to the IAWA List of microscopic features for hardwood identification ( IAWA 1989). The results so far obtained suggest that el cachichín wood is as resistant as pine wood and, for some mechanical properties, this is better than pine wood. Therefore, it is apt as building material, provided the whole bole is used; only if dimensions allowed, it could be saw for making prismatic pieces. |

Se describe por primera vez la anatomía de la madera de Oecopetalum mexicanum ( cachichín ) Greenm. & C.H. Thomps., la cual es una especie que crece en los bosques y ecosistemas de café de la sierra de Misantla, Veracruz, México. Con el fin de conocer sus posibles usos, se determinaron las propiedades mecánicas en flexión, del tipo: esfuerzo en el límite de proporcionalidad, trabajo unitario en el límite de proporcionalidad, módulo de elasticidad, módulo de ruptura y trabajo unitario a carga máxima; en compresión paralela a la fibra, como lo fue el esfuerzo máximo, esfuerzo en el límite de proporcionalidad y módulo de elasticidad. Todo ello, en su madera en condición verde. Se investigó también la densidad relativa básica de cada muestra, así como el diámetro, la distribución y densidad de los vasos, la abundancia y distribución del parénquima axial y radial. A partir de macerados, se identificó el tamaño de los elementos de vaso, tamaño de las fibras y contenidos celulares. La descripción anatómica se basó en la IAWA List of microscopic features for hardwood Identification (IAWA 1989) . Los resultados obtenidos a la fecha indican que la madera del cachichín tiene resistencia similar a la del pino y, en algunas propiedades, incluso lo supera. Por lo tanto, es apta para la construcción, siempre y cuando se utilice todo el tronco y solo cuando sea posible aserrarla, se usarán piezas prismáticas aserradas.
