Abstract
Passiflora jaenensis B.Esquerre is described and illustrated as a species new to science and endemic to Peru. According to a recent classification of Passiflora its placement within subgenus Passiflora, section Granadillastrum is proposed. This new species is morphologically similar to Passiflora sprucei Masters (1872: 568) and Passiflora subulata Masters (1872: 567) but it differs in features of the leaves, flowers and geographic distribution. Information about its habitat and preliminary distribution are included here.
