A recent expedition to the Cordillera Central of the Colombian Andes resulted in the discovery of a new species of Columnea (Gesneriaceae, tribe Episcieae). The new species, Columnea antennifera J.L. Clark & Clavijo, is distinguished from other congeners by the presence of elongate corolla appendages that alternate with the corolla lobes, anisophyllous leaves, and a scandent obligate epiphytic habit. A discussion and images are provided to differentiate Columnea antennifera from C. dissimilis, C. filamentosa, and C. rosea. The characteristic of elongate corolla appendages is discussed and Columnea antennifera is compared with other taxa that share this unusual feature
