Quararibea calycoptera (Malvaceae), a new species from the Pacific wet forests of Ecuador and Colombia
Background and Aims: The Quararibea (Malvaceae) tree genus, typical of the New World, groups about 60 species with a distribution centered in northern South America and southern Mesoamerica. As part of the revision work that is currently being carried out in a morphological group of Quararibea that...

| description | Background and Aims: The Quararibea (Malvaceae) tree genus, typical of the New World, groups about 60 species with a distribution centered in northern South America and southern Mesoamerica. As part of the revision work that is currently being carried out in a morphological group of Quararibea that presents a digitate staminal column, a new species from the wet forests of the Pacific of Ecuador and Colombia is described here, and its IUCN categorization is proposed. Methods: A group of herbarium collections of Quararibea from the wet forests of northern Ecuador, that showed some divergences with respect to the described species, was studied. The morphological diagnosis was realized, and the geographical distribution of these plants was delimited, which are described here as a different new taxon. Based on the known localities for the new species and in relation to its conservation, a first categorization proposal is made in accordance with the criteria of the IUCN.Key results: The new species Quararibea calycoptera, related to Q. grandifolia and Q. cornejoi, is described and graphically documented. It is separated morphologically from both species by the following characters: the consistency of the blade, the length of the floral pedicel and bracteoles, and the shape and size of the floral calyx. Conclusions: Within what had been identified as Quararibea grandifolia in western Ecuador, based on the study of new collections from the wet forests of Esmeraldas, it was possible to diagnose what represents a new species assignable to the small group of Quararibea species that has a digitate staminal column and winged calyces, currently under revision. |

Antecedentes y Objetivos: El género de árboles Quararibea (Malvaceae), propio del Nuevo Mundo, agrupa a unas 60 especies con distribución centrada en el norte de Sudamérica y sur de Mesoamérica. Como parte del trabajo de revisión que se está llevando a cabo en un grupo morfológico de Quararibea que presenta columna estaminal digitada, en este trabajo se describe una nueva especie proveniente de los bosques muy húmedos del Pacífico de Ecuador y Colombia y se propone su categorización IUCN. Métodos: Se estudió un grupo de colecciones de herbario de Quararibea, provenientes de los bosques muy húmedos del norte de Ecuador, que presentaban algunas divergencias morfológicas con respecto a las especies descritas en este género. Se realizó la diagnosis morfológica y se delimitó la distribución geográfica de estas plantas, proponiéndose aquí como un taxón nuevo. Asimismo, se hace una propuesta preliminar de categorización, de acuerdo con los criterios de la Lista Roja de la UICN.Resultados clave: Se describe y documenta gráficamente la nueva especie Quararibea calycoptera, como especie afín a Q. grandifolia y a Q. cornejoi, con las que se compara. La nueva especie se separa morfológicamente de ambas por los siguientes caracteres: la consistencia de la lámina, la longitud del pedicelo floral y bractéolas y la forma y tamaño del cáliz floral. Conclusiones: Dentro de lo que se había venido identificando como Quararibea grandifolia en el Occidente de Ecuador, con base en el estudio de nuevas colecciones de los bosques muy húmedos de Esmeraldas, pudo diagnosticarse lo que representa una nueva especie asignable al pequeño grupo de especies de Quararibea, con columna estaminal digitada y cálices alados, en proceso de revisión.
