Abstract

A new species of Passiflora subgenus Decaloba section Decaloba (Passifloraceae) is described from the Cordillera Oriental of Colombia. Passiflora tenensis sp. nov., is a narrow endemic and was discovered during an ecological survey in the Tena region of Cundinamarca department. The new species shows close morphological affinity to Passiflora bicornis and a new species currently described from Huila department, but is readily distinguished by differences in the shape of its foliaceous bracts, coloration of the flower, and distribution. Leaf morphology is distinct from other members of sect. Decaloba known to the region by being distinctly three-horned in the apical portion. This study compares similar species and discusses the taxonomy, distribution, ecology, and conservation status of Passiflora tenensis sp. nov.
