Abstract

Two new species of Epidendrum from the Western Cordillera of the Colombian Andes are described and illustrated. The new species with red and orange flowers belong to the Schistochilum group, Secundum subgroup and are similar to Epidendrum portokalium and E. melinanthum but differ by the color of the flowers and floral details, especially the calli. The new species were found in an open area with mild to severe erosion of the soil with a high clay content and high levels of insolation. The location was purchased with the aim of implementing ecological restoration strategies for its conservation with plans to recover the forest areas and allow connectivity within landscapes. The discoveries made it necessary to change the ecological restoration plans, the results being that it is not necessary to restore forest cover, but rather to maintain the area in its current state, making some changes that allow the conservation of the two new species and associated species.

Se describen e ilustran dos nuevas especies de Epidendrum de la Cordillera Occidental de los Andes colombianos. Las especies nuevas de flores rojas y anaranjadas pertenecen al grupo Schistochilum, subgrupo Secundum y son similares a Epidendrum portokalium y E. melinanthum pero se distinguen por su el colorido de las flores y los detalles florales y callos. Las nuevas especies se encontraron en un área abierta con erosión leve a severa del suelo, con un alto contenido de arcilla y una alta exposición al sol. Este lugar fue adquirido con el objetivo de implementar estrategias de restauración ecológica para su conservación con la finalidad de recuperar las áreas boscosas y permitir la conectividad dentro del paisaje. Los hallazgos obligaron a cambiar los planes de restauración ecológica, considerando que no es necesario restaurar la cobertura forestal, sino mantener el área en su estado actual, realizando algunos cambios que permitan la conservación de las dos nuevas especies y las especies asociadas.
