| description | Background and Aims: Loganiaceae is a group of tropical plants, which have been poorly studied in Mexico. Some of the taxa are little known in terms of their taxonomy and distribution, such as the genus Mitreola, where additionally some of the species have nomenclatural problems. This work focuses on a taxonomic review of Mitreola petiolata and solves the nomenclatural problems that the species has had over the years.Methods: A review of specimens in different herbaria was carried out, specialized literature to obtain descriptions and taxonomic keys, the number of species of the genus and their distribution, as well as the circumscription and nomenclatural problems of the taxon. To obtain the palynological data, material from mature flowers was acetylated and revised with the scanning electron microscope. From these data an evaluation of the conservation situation was obtained.Key results: Mitreola petiolata has a pantropical distribution and is the only species of the genus present in the country, growing from Tamaulipas and Sinaloa to the Yucatán Peninsula. In spite of the morphological variation of structures such as the leaves or the lobes of the capsule, the characters of taxonomic importance (dichotomic inflorescence, subsessile flowers and stamens inserted close to the base of the corolla) remain constant.A review for M. petiolata, a dichotomous key, data on its distribution and conservation status in the country is provided. Detailed information on the micromorphology of pollen grains is presented, the first made for the species. The category of Least Concern is suggested, due to its wide distribution.Conclusions: The constant revision and curation of biological collections, keeps knowledge of taxa updated. This is the case of Mitreola petiolata, for which an update of its systematics, distribution and state of conservation is provided. |

Antecedentes y Objetivos: Loganiaceae es un grupo de plantas tropicales que se han estudiado escasamente en México. Algunos de sus taxones son poco conocidos en cuanto a su taxonomía y distribución, como el caso del género Mitreola, en el que además algunas de sus especies tienen problemas nomenclaturales. Este trabajo presenta una revisión taxonómica de Mitreola petiolata y resuelve los problemas nomenclaturales que ha tenido a lo largo de los años.Métodos: Se revisaron especímenes en diferentes herbarios, literatura especializada para la obtención de descripciones y claves taxonómicas, número de especies del género y su distribución; así como la circunscripción y problemas nomenclaturales del taxon. Para la obtención de los datos palinológicos, se acetolizó material de flores maduras y se revisó en el microscopio electrónico de barrido. A partir de los datos obtenidos se obtuvo una evaluación de la situación de conservación.Resultados clave: Mitreola petiolata tiene una distribución pantropical y es la única especie del género presente en el país. La especie se extiende desde Tamaulipas y Sinaloa hasta la Península de Yucatán. A pesar de la variación morfológica de estructuras como las hojas o los lóbulos de la cápsula, los caracteres de importancia taxonómica (inflorescencias dicotómicas, flores subsésiles y estambres insertos cerca de la base de la corola) se mantienen constantes. Se proporciona una revisión para M. petiolata, una clave dicotómica, datos sobre su distribución y estado de conservación en el país. Se presenta información detallada sobre la micromorfología de los granos de polen, la primera hecha para la especie. Se sugiere la categoría de preocupación menor por su amplia distribución.Conclusiones: La constante revisión y curación de las colecciones biológicas mantiene actualizado el conocimiento de los taxones. Tal es el caso de M. petiolata, para la cual se proporciona una actualización de su sistemática, distribución y estado de conservación.
