Abstract
in English, French

A new species of Glossoloma is described from the western Andean slopes of the Pichincha Province in northern Ecuador. Glossolomawiehleri J.L.Clark & Tobar is differentiated from all other congeners by an epiphytic habit, elongate scandent shoots that exceed four meters in length, and coriaceous leaves with a velutinous indument on the lower leaf surface. The new species is illustrated, featured with field images from recent expeditions, and assigned the category of Endangered (EN) according to IUCN Criteria.

ResumenSe describe una nueva especie de Glossoloma de las laderas occidentales de la provincia Pichincha en el norte de Ecuador. Glossolomawiehleri J.L.Clark & Tobar se diferencia de todos sus otros congéneres por su hábito epífito, ramas escandentes alargadas que superan los cuatro metros de longitud y hojas coriáceas con un indumento velutino en la superficie inferior de la hoja. La nueva especie se ilustra con imágenes de campo de expediciones recientes y se le asigna la categoría de En Peligro (EN) de acuerdo a los criterios de la IUCN.
