Two new species were found during a taxonomic revision of Passiflora subg. Decaloba (DC.) Rchb. (Passifloraceae). Both new species are described and placed in the P. lobbii Mast. species group. Passiflora joergenseniana T. Boza is from La Paz, Bolivia, and P. praemorsa T. Boza is from Cusco, Peru, and is also distributed in La Paz, Bolivia. Conservation assessments and geographic distributions for each species are provided, and morphological variability within each species is discussed. Similarities to and differences among these new species and putative close relatives are also examined.
