Clinanthus longissimus B. Esquerre & Meerow sp. nov. is described from the Department of Cajamarca in northwest Peru. This new species has affinity with C. coccineus (Ruiz. & Pav.) Meerow, C. incarnatus (Kunth) Meerow and C. variegatus (Ruiz & Pav.) Meerow, from which it can be distinguished mainly by the length of the flower, the continuous floral tube without protuberances, the size of the staminal cup and the color of the tepals. C. longissimus is so far known only from the Province of Cutervo.

Boris Esquerre-Ibañez A new species of Passiflora Section Decaloba, P. andicola, endemic in northwest Peru is here described and illustrated. This new herbaceous climber differs from its related species in the indumentum, flower morphology and geographical distribution. Passiflora andicola inhabits montane forests of Cajamarca and Lambayeque Departments. In addition, the morphology and distributional range of P. andicola and related species are compared and discussed.

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.

A new species, Passiflora kuethiana (Passifloraceae) is described and illustrated from Cordillera Calla Calla, Amazonas Department, Northern Peru. This species shares morphological characteristics more related with Passiflora tripartita and Passiflora runa on stipules and flowers but differs mainly from the former in the size, shape and color of the involucre, peduncles length and arrangement, and the latter in shape and margin of stipules. This species is considered as a new endemic to the Peruvian flora. Its location within the section Elkea according to the new classification of Passiflora is proposed. Comparative data of related species and a key to the species of the section Elkea from Northern Peru are too added.
