In Spanish, English and Spanish abstracts.Chionanthus abriaquiensis Fern. Alonso & Cogollo (Oleaceae), a new species from the cloud forests of Colombia, is described and illustrated. This species clearly differs from the previously known Chionanthus L. in Mesoamerica and Northern South America for the long petiolate leaves, the number of secondary veins on the blades, and very long axillary inflorescences. An identification key for the species of Chionanthus from Northern South America and Panama is also presented.
