Columnea versicolor, a new species of Gesneriaceae from the cordillera occidental in the Colombian Andes

Exploratory field expeditions and herbarium research have led to the discovery of Columnea versicolor J.L. Clark & Clavijo, sp. nov. in the flowering plant family Gesneriaceae. The new species is distinguished from congeners by a distinctly bicolored corolla, with the tube uni- formly magenta with dark purple lobes, or magenta with a purple section and dark purple lobes. The species is endemic to the western slopes of the Cordillera Occidental in the Colombian Andes.
