Taxonomic novelties and synopsis of the genus Blakea (Melastomataceae, Pyxidantheae) in the Eastern Cordillera, Colombia

| description | Background and Aims: Blakea is a Neotropical genus of woody plants with 192 species, of which more than 80 are distributed in Colombia, with high levels of endemism. Despite the high diversity of the genus in the country, few taxonomic studies have been carried out at the regional level, so that knowledge about Blakea is scarce in general. This paper deals with a taxonomic synopsis of the genus for the Eastern Cordillera of Colombia, nomenclatural novelties are proposed, and a new species is described.Methods: More than 200 specimens from different herbaria in Colombia were reviewed; in addition, the prologues and type specimens were consulted online and compiled. The richness and distribution of the genus in the region are established, annotations are made on its phenology, conservation status and a representative specimen per department are cited. Taxonomic comments are also made on some species.Key results: In total, 25 species and one variety were recorded for the study area, one of which was identified at the morphospecies level. A new species is described within the study area (Blakea reflexa), B. clusiifolia is reestablished, B. schlimii is reported for the country and the departmental and elevational distributions of 12 species are expanded.Conclusions: Blakea presents a high richness in the Eastern Cordillera of Colombia, so this area is key for the study and conservation of the group at regional and national levels. It is important to continue with detailed regional taxonomic studies of the genus to precisely know its current status and possible future trends. |

Antecedentes y Objetivos: Blakea es un género Neotropical de plantas leñosas con 192 especies, de las cuales más de 80 se distribuyen en Colombia, con altos niveles de endemismo. A pesar de la alta diversidad del género en el país, pocos son los estudios taxonómicos realizados a nivel regional, por lo que el conocimiento sobre Blakea es escaso en general. En este trabajo se aborda una sinopsis taxonómica del género para la Cordillera Oriental de Colombia, se proponen novedades nomenclaturales y se describe una nueva especie.Métodos: Se revisaron más de 200 ejemplares de diferentes herbarios de Colombia; además, se consultaron en línea y se recopilaron los protólogos y ejemplares tipo. Se establecen la riqueza y distribución del género en la región, se hacen anotaciones sobre su fenología, estado de conservación y se presenta un ejemplar representativo por departamento. Además, se realizan comentarios taxonómicos en algunas especies.Resultados clave: En total, se registraron 25 especies y una variedad para el área de estudio, una de las cuales se identificó a nivel de morfoespecie. Se describe una especie nueva dentro del área de estudio (Blakea reflexa), se restablece a B. clusiifolia, se reporta para el país a B. schlimii y se amplía la distribución departamental y altitudinal de 12 especies.Conclusiones: Blakea presenta una alta riqueza en la Cordillera Oriental de Colombia, por lo que esta zona es clave para el estudio y la conservación del grupo a nivel regional y nacional. Es importante continuar con aproximaciones taxonómicas detalladas sobre el género para conocer de forma precisa su estado actual y sus posibles tendencias futuras.turas.
