Taxonomy, and geographic and ecological distribution of the genus Penstemon (Plantaginaceae) in the Trans-Mexican Volcanic Belt, Mexico
background and Aims: Penstemon is one of the most diverse genera within Plantaginaceae, with around 283 species occurring from Alaska to Guatemala. At least 50 species are cited in the literature for Mexico; however, until now little is known about their taxonomy, distribution, diversity as well as...

| description | background and Aims: Penstemon is one of the most diverse genera within Plantaginaceae, with around 283 species occurring from Alaska to Guatemala. At least 50 species are cited in the literature for Mexico; however, until now little is known about their taxonomy, distribution, diversity as well as their conservation status. Due to the richness, the composition and the endemism of the flora of the Trans-Mexican Volcanic Belt, it is considered as an important region to realize a first approximation of the knowledge about the genus Penstemon in Mexico.Methods: Floristic treatments of the Trans-Mexican Volcanic Belt, online databases as well as taxonomic studies of the genus were analyzed, specimens of Penstemon deposited in 12 herbaria in central Mexico were revised and the conservation status of each species was evaluated. In addition, we analyzed the distribution patterns of the Penstemon species from the study area through a quantitative biogeographic study.Key results: We documented and analyzed the distribution patterns of nine taxa of Penstemon for the Trans-Mexican Volcanic Belt. We listed the taxa found as well as valid names, synonyms, morphological descriptions, conservation status, and distribution maps.Conclusions: Although no endemic Penstemon taxa of the Trans-Mexican Volcanic Belt were found, it is important to note that the largest part of the distribution area of five of the nine treated taxa is concentrated in this province. Moreover, it was discovered that the eastern portion of the Trans-Mexican Volcanic Belt is the region where the largest species richness of the studied genus occurs. |

Antecedentes y Objetivos: Penstemon es uno de los géneros más diversos de la familia Plantaginaceae con cerca de 283 especies distribuidas desde Alaska hasta Guatemala. Para México se citan al menos 50 especies; sin embargo, hasta la fecha se conoce muy poco sobre su taxonomía, distribución, diversidad y estado de conservación. Considerando la riqueza, composición y grado de endemismo de la flora de la Faja Volcánica Transmexicana, se piensa que es una región esencial para realizar un primer acercamiento sobre el conocimiento del género Penstemon en México.Métodos: Se analizaron los estudios florísticos de la Faja Volcánica Transmexicana, bases de datos en línea y los tratamientos taxonómicos de Penstemon; se revisaron los ejemplares del género depositados en 12 herbarios del centro de México y se evaluó el estado de conservación de sus especies. Además, se analizaron los patrones de distribución geográfica y ecológica de las especies de Penstemon en la provincia de estudio a través de un análisis biogeográfico cuantitativo.Resultados clave: Se documenta la presencia, y se analizan patrones de distribución, de nueve taxa de Penstemon para la Faja Volcánica Transmexicana. Se enlistan los taxa encontrados, nombres válidos, sinonimias, descripciones morfológicas, estado de conservación y mapas de distribución.Conclusiones: Aunque no se localizó ningún taxón de Penstemon endémico de la Faja Volcánica Transmexicana, es importante señalar que en esta provincia se concentra la mayor parte del área de distribución de cinco de los nueve taxa tratados. Además, se descubrió que la porción oriental de la Faja Volcánica Transmexicana es la región donde se registra la mayor riqueza de especies del género de estudio.
