Identity and distribution of Bouteloua reederorum (Poaceae: Chloridoideae), a species endemic to Mexico
Background and Aims: Bouteloua is one of the most important genera in North American grasslands, especially in Mexico, where 92% of the taxa described for this group are distributed, 25 of which are endemic. One of these is Bouteloua reederorum, which has been confused with B. stolonifera, causing i...

| description | Background and Aims: Bouteloua is one of the most important genera in North American grasslands, especially in Mexico, where 92% of the taxa described for this group are distributed, 25 of which are endemic. One of these is Bouteloua reederorum, which has been confused with B. stolonifera, causing it to be reported in states of the republic where it is not found. The aim of the present work is to clarify the identity of B. reederorum and provide a detailed morphological description with photographs of important structures for its identification, as well as a distribution map for this species.Methods: The material deposited in the herbaria ARIZ, HUAA, HUAP, HUMO, IEB, INEGI, MEXU, XAL, the digital collections MO, P and US, and the platform JSTOR, were reviewed to obtain records of B. reederorum. Based on this information, collection points were determined, which were visited from September 2017 to August 2019 in search of populations of this species, where specimens were collected. The collected material was identified and reviewed to prepare a morphological description accompanied with photographs of important characteristics for the identification of the species. With the obtained records, a distribution map of B. reederorum was made.Key results: Bouteloua reederorum and B. stolonifera can be easily distinguished by several morphological characteristics such as branching of their inflorescences and the ligule shape. Bouteloua reederorum is practically restricted to the Tehuacán-Cuicatlán Valley, located between Puebla and Oaxaca. Although the male spikelets of B. reederorum generally do not have rudimentary florets, they can rarely develop one similar to that of the female spikelets.Conclusions: Bouteloua reederorum is different from Bouteloua stolonifera (= Cyclostachya stolonifera). Phenological studies are necessary to determine if B. reedeorum can be dioecious. |

Antecedentes y Objetivos: Bouteloua es uno de los géneros más importantes en los pastizales de Norteamérica, especialmente en México, donde se distribuye 92% de los taxones descritos para este grupo, 25 de los cuales son endémicos. Uno de estos es Bouteloua reederorum, que ha sido confundido con B. stolonifera, ocasionando que sea reportado en estados de la república en donde no se encuentra. El objetivo del presente trabajo es aclarar la identidad de B. reederorum y proporcionar una descripción morfológica detallada con fotografías de estructuras importantes para su identificación, así como un mapa de distribución para esta especie.Métodos: Se revisó el material depositado en los herbarios ARIZ, HUAA, HUAP, HUMO, IEB, INEGI, MEXU, XAL y las colecciones digitales MO, P y US y la plataforma JSTOR, para obtener registros de B. reederorum. Con base en esta información se determinaron los puntos de colecta, que fueron visitados de septiembre de 2017 a agosto de 2019 en busca de poblaciones de esta especie, donde se colectaron ejemplares. El material colectado fue identificado y revisado para elaborar una descripción morfológica con fotografías de características importantes para la identificación de la especie. Con los datos tomados en campo, material de herbario y colecciones digitales se realizó un mapa de distribución de B. reederorum.Resultados clave: Bouteloua reederorum y B. stolonifera pueden distinguirse fácilmente por caracteres morfológicos como la ramificación de sus inflorescencias y la forma de la lígula. Bouteloua reederorum se encuentra restringida al Valle de Tehuacán-Cuicatlán, ubicado entre Puebla y Oaxaca. Aunque generalmente las espiguillas masculinas de B. reederorum no tienen flósculos rudimentarios, en raras ocasiones pueden desarrollar uno, similar al de las espiguillas femeninas.Conclusiones: Bouteloua reederorum es distinta de Bouteloua stolonifera (= Cyclostachya stolonifera). Es necesario realizar estudios fenológicos para determinar si B. reedeorum puede ser dioica.
