Abstract
A narrowly endemic new species of Glossoloma is described from the Cordillera Oriental of the northern Andes, in the Colombian departments of Caquetá and Huila. Glossoloma magenticristatum J.L.Clark, D.Hoyos & Clavijo, sp. nov. differs from most other congeners by a habit that is usually epiphytic with elongate scandent subwoody shoots, the presence of a magenta corolla tube, and a creased calyx formed by tightly appressed adjacent lobes. A brief summary of Gesneriaceae diversity in the Colombia departments of Caquetá and Huila is discussed with an emphasis on the old highway between Florencia and Guadalupe. The conservation status of G. magenticristatum is assessed as Endangered (EN) based on IUCN Criteria.

Glossoloma magenticristatum J.L.Clark, D.Hoyos & Clavijo, sp. nov.
Diagnosis: Differs from all other Glossoloma by the presence of a magenta corolla tube and a creased calyx formed by tightly appressed adjacent lobes.
Etymology: The specific epithet is derived from two adjectives that reflect the unique characteristics of Glossoloma magenticristatum. The corolla is magenta, a color not found in other members of Glossoloma. The adjacent calyx lobes are tightly appressed and form a crease that appears winged or crested (Fig. 2B), which reflects the second part of the specific epithet, “cristate.”

Resumen: Se describe una especie de Glossoloma endémica de la Cordillera Oriental de los Andes del norte, en los departamentos de Caquetá y Huila. Glossoloma magenticristatum J.L.Clark, D.Hoyos & Clavijo, sp. nov. se diferencia de otras especies en el género por el hábito usualmente epífito con ramas alargadas, escandentes y subleñosas, el tubo de la corola magenta, y un cáliz con los lóbulos estrechamente adpresos y con margen ondulada. Se presenta una breve síntesis de la diversidad de Gesneriaceae en los departamentos de Caquetá y Huila, con un énfasis en la vieja carretera entre Florencia y Guadalupe. Se evalúa el estado de conservación de G. magenticristatum y se propone que se debería categorizar como En Peligro (EN), de acuerdo a los criterios de la UICN.
