Abstract
Grias lucindoae, a new species from the Western Andean slopes of the Eastern Cordillera of Colombia (Serranía de Las Quinchas), is described and illustrated, and its morphological similarities with comparable species are discussed. This new species is a tree between 10 and 15 m tall from montane forest remnants (900–1200 m). Grias lucindoae shares several features with G. angustipetala and G. cauliflora. It differs in the size and pubescence of the leaf blade, pedicels, the number of secondary veins and stamens, calyx dehiscence, size, shape, and color of the petals, and the 4-lobed stigma, which is truncated when mature. Additionally, a table comparing morphological characters of G. lucindoae to the other Grias species that occur in Colombia is presented, as well as an identification key of the Neotropical species. With this new species, there are now nine species of Grias in the flora of Colombia, which, along with Ecuador, are countries with the highest diversity of the genus.
Resumen
Grias lucindoae, una nueva especie de la vertiente occidental de la Cordillera Oriental, Andes de Colombia (Serranía de Las Quinchas), es descrita, ilustrada y se discuten sus relacioness morfològicas con las especie afines. Esta nueva especie es un árbol entre 10 y 15 m de altura, el cual se encuentra en remanentes de bosques montanos (900–1200 m). G. lucindoae es similar a G. angustipetala y G. cauliflora, de las cuales difiere en el tamaño y pubescencia de las hojas, pedicelos, en el número de las venas secundarias y estambres, dehiscencia del cáliz, tamaño, forma y color de los pétalos y el estigma 4-lobado, truncado en la madurez. Adicionalmente, se incluyen, una tabla comparativa de los caracteres morfológicos de G. lucindoae, con las otras especies Grias que se encuentan en Colombia y una clave para las especies neotropicales. Esta nueva especie eleva a nueve el número de especies para la flora de Colombia. Actualmente, Colombia y Ecuador son los países con la mayor diversidad del género.
