En este contexto es necesario generar información para la identificación taxonómica de Pinus, únicamente con base en caracteres anatómicos de acículas en individuos jóvenes que carecen de estróbilos femeninos. El objetivo del presente estudio fue establecer una clave dicotómica para la identificación de pinos de Hidalgo, a partir de su anatomía foliar. Se recolectaron ejemplares en diversas localidades, se obtuvieron cortes transversales de las acículas, con ellos se codificó una matriz de caracteres, la cual fue sometida a un análisis de similitud UPGMA; y se elaboró una clave taxonómica. Se logran diferenciar 10 de los 12 taxones, que incluyen a Pinus greggii, especie bajo categoría de riesgo. Pinus cembroides se diferencia de P. pinceana, solo cuando la forma de la acícula, en corte transversal, es semicircular. Los canales resiníferos externos se observaron solamente en individuos del subgénero Strobus; y los septales en P. oocarpa. El número de canales resiníferos es utilizado de manera complementaria para identificar, debido a su alta variación. El análisis UPGMA resultó en dos agrupaciones principales, en la primera se recuperaron dos subgrupos correspondientes a las especies del subgénero Strobus y del subgénero Pinus; en la segunda pertenecen al subgénero Pinus. Se concluye que la clave es robusta para la identificación de especies de pinos a escala local, exclusivamente mediante caracteres anatómicos foliares.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: Twelve pine species naturally occur in the state of Hidalgo, of which, Pinus pinceana and P. greggii are listed as threatened. In this context it is necessary to generate information for Pinus species identification specially for immature individuals without seed cones. In this study we establish an identification key based on leaf anatomy for the identification of pine species occurring in the state of Hidalgo. Specimens from different localities were collected from which, permanent slides were prepared from transverse leaf sections and a character matrix was codified from leaf anatomy features and analyzed with UPGMA. The matrix was used to construct an identification key. The key allow for the identification of 10 out of the 12 species, including Pinus greggii a species under risk category. Pinus cembroides can only be differentiated from P. pinceana when it exhibits a semicircular shape in transverse section. External resin canals were only observed in Pinus subgenus Strobus and septal resin canals were only recorded for P. oocarpa. The number of resin canals may only be used as complementary for identification because of its high variation. UPGMA analysis generated two principal clusters, the first group included two interior clusters corresponding with subgenus Strobus species and subgenus Pinus species, the second principal cluster included only species from subgenus Pinus. This study contributes with a robust identification key for pine species at a local scale exclusively using secondary leaf anatomy characters.]]></p></abstract>
