| description | Background and Aims: One of the most recent approaches to delimiting plant species is using anatomical wood characters in woody taxa, which has been little explored in Mexican representatives. The genera Forestiera is an example of this, since only the wood of two of the 12 species distributed in Mexico have been described. With the aim of contributing to the knowledge of the wood anatomy of the genera, as well as the search for anatomical characters that discriminate between their species, this study describes the wood anatomy of the wood of eight species of Forestiera distributed in Mexico, with a systematic approach.
Methods: Wood from 42 wood samples from eight species were analyzed, with three individuals per species at 14 collection sites. The material was processed with conventional microtechniques to obtain qualitative and quantitative anatomical variables. Characters were evaluated with multivariate statistics to determine which ones are important to form groups of species in Forestiera.
Key results: Some previously reported anatomical attributes agree with those observed in this paper. However, there are differences such as semi-ring porous wood and growth marks without marginal parenchyma. The analyses formed groups of species, based the diameter of early-wood vessels, length of vessel elements and fibers, diameter of the fibers, type of rays, abundance of the marginal parenchyma and the type of crystals in rays. Based on wood anatomy, a taxonomic key is proposed to identify the studied species.
Conclusions: Through the used analyses, we contribute to the knowledge of Forestiera anatomy. Wood characters that allow to distinguish groups of species are recognized. Future studies will confirm their taxonomic value. |

Antecedentes y Objetivos: Uno de los enfoques más recientes para delimitar especies vegetales es el uso de caracteres anatómicos de la madera en representantes leñosos que ha sido poco explorado en taxones mexicanos. El género Forestiera (Oleaceae) es un ejemplo de esto, pues solo se ha descrito la madera de dos de las 12 especies distribuidas en México. Con el objetivo de contribuir al conocimiento de la anatomía de la madera del género, así como a la búsqueda de caracteres anatómicos que discriminen entre sus especies, en el presente estudio se describe la anatomía de la madera de ocho especies de Forestiera distribuidas en México con un enfoque sistemático. Métodos: Se analizaron 42 muestras de madera de ocho especies, provenientes de tres individuos por especie en 14 sitios de colecta. El material se procesó con microtecnia convencional para obtener variables anatómicas cualitativas y cuantitativas. Estas fueron evaluadas con estadística multivariada para determinar cuáles son importantes para formar grupos de especies en Forestiera. Resultados clave: Algunos atributos anatómicos reportados anteriormente coinciden con los observados en este trabajo. Sin embargo, hay diferencias como la porosidad semianular y la delimitación de marcas de crecimiento sin presencia de parénquima marginal. Los análisis formaron grupos de especies dados por el diámetro de vasos de la madera temprana, longitud de elementos de vaso y fibras, diámetro de las fibras, tipo de radios, abundancia del parénquima marginal y tipo de cristales en los radios. Con base en la anatomía de la madera, se propone una clave taxonómica para identificar las especies estudiadas. Conclusiones: Mediante los análisis empleados se contribuye al conocimiento de la anatomía de la madera de Forestiera; además, se reconocen caracteres que permiten distinguir grupos de especies. Futuros estudios confirmarán su valor taxonómico.
