| description | Background and Aims: The genus Meriania has 120 neotropical species, 51 of them in Colombia. This work deals with the taxonomic review of the genus for Colombia, documenting species, subspecies, and synonyms.
Methods: A total of 660 specimens of Meriania from 24 herbaria from Colombia, Ecuador, the United States of America, and England were reviewed and evaluated, and the protologues and images of type specimens in JSTOR Global Plants of the species present in Colombia were consulted. A detailed description of the genus, an identification key, as well as descriptions, illustrations, distribution maps and threat categories are established for each of the species present in Colombia.
Key results: Meriania is characterized by petals ≥9 mm long, nongeniculate stamens, anthers of antepetalous stamens with dorsally inclined pores, capsular fruits and seeds with a straight embryo. Two new species (M. neilli and M. ramosii) and three new subspecies of M. macrophylla (M. macrophylla subsp. antioquiensis, M. macrophylla subsp. franciscana and M. macrophylla subsp. peltata) are described. In addition, 18 new synonyms are established and 19 lectotypifications are carried out. The species in Colombia are distributed in the Andean region (34 spp.), Sierra Nevada de Santa Marta (2 spp.), and Guiana Shield-Orinoquia (2 spp.), between 100 and 3700 m a.s.l. Threat categories are documented for 31 species, while six species were not categorized because most of their distribution ranges are found in other countries.
Conclusions: With this revision, Meriania consists of 102 species, 37 of them present in Colombia. Andean species (33 spp.) can be considered within Meriania s.s., while four species found in lowland areas of the Magdalena Medio and Guiana Shield-Orinoquia could be considered as different genera in the future, based on anthers characters, ovary locule number, and seminal rudiment arrangement. |

Antecedentes y Objetivos: El género Meriania cuenta con 120 especies neotropicales, 51 de ellas en Colombia. En este trabajo se aborda la revisión taxonómica del género para Colombia; se documentan especies, subespecies y sinónimos nuevos. Métodos: Se revisaron y evaluaron 660 ejemplares de Meriania de 24 herbarios de Colombia, Ecuador, Estados Unidos de América e Inglaterra y se consultaron los protólogos e imágenes de ejemplares tipo en JSTOR Global Plants de las especies presentes en Colombia. Se establece una descripción detallada del género, una clave de identificación, descripciones, ilustraciones, mapas de distribución y categorías de amenaza para cada una de las especies presentes en Colombia. Resultados clave: Meriania se caracteriza por presentar pétalos ≥9 mm de largo, estambres no geniculados, anteras en estambres opositipétalos con poros dorsalmente inclinados, frutos capsulares y semillas con embrión recto. Se describen dos especies nuevas (M. neillii y M. ramosii) y tres subespecies nuevas de M. macrophylla (M. macrophylla subsp. antioquiensis, M. macrophylla subsp. franciscana y M. macrophylla subsp. peltata). Se establecen 18 sinónimos nuevos y se realizan 19 lectotipificaciones. Las especies en Colombia se distribuyen en la región Andina (34 spp.), en la Sierra Nevada de Santa Marta (2 spp.) y en el Escudo Guayanés-Orinoquia (2 spp.), entre 100 y 3700 m s.n.m. Se documenta la categoría de amenaza para 31 especies, mientras que seis no se categorizaron por su mayor distribución en otros países. Conclusiones: Con la presente revisión, Meriania queda constituido por 102 especies, 37 de ellas presentes en Colombia. Las andinas (33 spp.) se pueden considerar dentro del grupo de Meriania s.s., mientras que cuatro de zonas bajas del Magdalena Medio y Escudo Guayanés-Orinoquia, podrían considerarse a futuro como géneros distintos con base en caracteres de las anteras, número de lóculos del ovario y disposición de los rudimentos seminales.
