Two new species of Caryodaphnopsis (Lauraceae) from the Magdalena Medio, Colombia, with an updated key for the Neotropical Caryodaphnopsis species
Background and Aims: Caryodaphnopsis is a tropical genus with an amphi-Pacific distribution, comprising 19 species, 10 of which Neotropical. Two new species are described from wet forest remnants on the western slopes of the Eastern Cordillera of Colombia, which is part of the Magdalena Medio biogeo...

| description | Background and Aims: Caryodaphnopsis is a tropical genus with an amphi-Pacific distribution, comprising 19 species, 10 of which Neotropical. Two new species are described from wet forest remnants on the western slopes of the Eastern Cordillera of Colombia, which is part of the Magdalena Medio biogeographical region. Their morphological relationships with Neotropical allied species are discussed.Methods: Descriptions and illustrations of both new species were based on collections from the Santander and Boyacá departments, deposited in the herbaria of the Bogotá Botanical Garden (JBB) and the Universidad Industrial de Santander (UIS). Measurements of vegetative parts and inflorescences were taken from herbarium material. Floral structures and fruits were measured from fresh material preserved in alcohol. Threat categories were proposed according to IUCN criteria.Key results: Caryodaphnopsis carmensis and C. yariguiensis are two species so far known only from the Magdalena Medio, Colombia. Caryodaphnopsis carmensis is unique because of its dense, golden pubescence on vegetative parts, leaves with subcordate base and 14-17 arcuate tertiary veins, located between the first pair of secondary veins. Caryodaphnopsis yariguiensis resembles C. fieldii but differs from the latter by the shape of leaves and the stamens with a pair of glands located between the middle portion of filament. Both taxa are proposed as Endangered (EN). An updated key for the Neotropical Caryodaphnopsis species is presented, along with information about their geographic distribution.
Conclusions: The two species described are trees that yield one of the finest timbers in the Magdalena Medio and their populations are much reduced. We encourage their cultivation to promote their conservation. With these two new species, Colombia is the country with the greatest diversity of the genus (seven) and the Magdalena Medio has the highest concentration of endemic species (three). |

Antecedentes y Objetivos: Caryodaphnopsis es un género tropical con distribución anfipacífica, cuenta con 19 especies, 10 de ellas neotropicales. Se describen dos nuevas especies de Caryodaphnopsis provenientes de bosques húmedos de la vertiente occidental de la Cordillera Oriental de Colombia, que forma parte de la región biogeográfica del Magdalena Medio. Se discuten sus diferencias morfológicas con las especies afines.Métodos: Se describen e ilustran dos nuevas especies de Caryodaphnopsis a partir de colecciones provenientes de los departamentos Boyacá y Santander, depositadas en los herbarios del Jardín Botánico de Bogotá (JBB) y de la Universidad Industrial de Santander (UIS). Las medidas de las partes vegetativas e inflorescencias se realizaron del material de herbario. Las estructuras florales y frutos se midieron a partir de material fresco conservado en alcohol. Se proponen sus categorías de amenaza acorde con los criterios de la IUCN. Resultados clave: Caryodaphnopsis carmensis y C. yariguiensis son dos especies solo conocidas del Magdalena Medio, Colombia. Caryodaphnopsis carmensis es única por su pubescencia densa dorada en las partes vegetativas, las hojas con base subcordada y 14-17 venas terciarias, arqueadas, situadas entre el primer par de venas secundarias. Caryodaphnopsis yariguiensis posee caracteres que la asemejan con C. fieldii, pero difiere de esta última en la forma de las hojas y en los estambres con un par de glándulas situadas entre la parte media del filamento. Se propone para ambos taxones la categoría de Amenazada (EN). Se presenta una clave actualizada de las especies neotropicales, acompañada con información acerca de su distribución geográfica.Conclusiones: Las dos especies aquí descritas son árboles que poseen una de las maderas más finas del Magdalena Medio y sus poblaciones se encuentran muy reducidas. Se propone su propagación y cultivo para promover su conservación. Con estas dos nuevas especies, Colombia es el país con mayor diversidad del género (siete), y el Magdalena Medio la región con la mayor concentración de especies endémicas (tres).
