Abstract

We describe and illustrate Catasetum kamatawara from the Loreto Department of the Amazonian wetlands in Peru. An extensive comparison with several related species is presented including Catasetum cotylicheilum which is morphologically close to our species but differs mainly in having a three-lobed labellum with a three-dentate apex formed by its obtuse apices of lateral lobes and mid-lobe (vs. unlobed labellum with obtuse-rounded apex), and the presence of 4–5 transversely verrucose keels (vs. elevated, smooth callus). Additionally, we also report C. boyi, C. longifolium and C. semicirculatum which have not been previously reported for the Peruvian orchid flora. Finally, we propose a lectotype for the rare C. peruvianum based on the original illustration of the species.

Funding Details

This work was partially supported by CONCYTEC and UCSUR under the project “Genetic and morphological characterization of species of Vanilla (Orchidaceae) in Peru” during which the new species was collected. Alexander Damián and Nicole Mitidieri designed this research project, analyzed the herbarium specimens, performed the taxonomic study, and drafted the manuscript. Miguel Bonilla analyzed the herbarium material and contributed on the taxonomic study of the new species. Javier Huayllani provided samples and photographs of C. semicirculatum. The authors are very grateful to the curators of USM, MOL, CUZ, HUT, CPUN, PRG, and MO for their kindness in allowing the revision of their collections as well as Shirley Graham and the Missouri Botanical Garden for awarding the first author a fellowship to study their unique collection. We also thank John Janovec, Yeri Dewevre, Luis Huaman (OrquideasTingo Maria), Sergio Olortegui (Musas Amazonicas) and Bruno Vasquez (Orquideas Amazonicas) for providing the photographs used in this manuscript and Gustavo Romero from the AMES herbarium at Harvard for his initial insightful suggestions that improved the manuscript and confirmed the identity of Catasetum boyi. Finally, our greatest gratitude to “Concesion para Conservacion El Guacamayo ” who allowed us explore its lands and facilitated field work.
