    In preparation for the Flora Neotropica monograph of Macrocarpaea (Gentianaceae: Helieae) and recent fieldwork in Ecuador, six new species have been identified and are here described from Parque Nacional Podocarpus and its surrounding areas in Loja and Zamora-Chinchipe provinces. These are Macrocarpaea apparata, M. bubops, M. jensii, M. lenae, M. luna-gentiana, and M. noctiluca. For each new species, descriptions, illustrations, and ecological information are provided. The neotropical montane genus Macrocarpaea has among the highest biodiversity in Ecuador with over 30 species present. The name “moon-gentian” or “genciana de luna” is coined as the common name for the genus Macrocarpaea.

    DE MACROCARPAEAE GRISEBACH (EX GENTIANACEIS) SPECIEBUS NOVIS I: AN INTRODUCTION TO THE GENUS MACROCARPAEA AND THREE NEW SPECIES FROM COLOMBIA, ECUADOR, AND GUYANA

    A monographic revision of the neotropical genus Macrocarpaea (Gentianaceae: Helieae) has been initiated. The taxonomic and nomenclatural background is provided as an introduction in this first of several papers. These gentians are typically montane shrubs with large, funnelform, night-blooming, bat-pollinated flowers and have a high rate of species endemicity. It is also an excellent group from which to study neotropical montane biogeography, since they occur in all major neotropical montane habitats. Three new species are described and illustrated: Macrocarpaea angelliae (Ecuador) in discussion with M. stenophylla where a neotype is selected, M. ayangannae (Guyana), and M. luteynii (Colombia). New synonymy is reported for one published species [Macrocarpaea guttifera = Ravenia biramosa (Rutaceae)] and six “nomen herbariorum”: “Axelsonia globiflora Dusén, ined.” = M. rubra, “M. buchtienii Gilg, ined.” = M. cinchoniifolia, “M. ekmanii Ewan, ined.” = M. pinetorum, “M. gilgiana Rusby, ined.” = M. cochabambensis, “M. peduncularis Rusby, ined.” = M. bangiana, and “M. tabacifolia Ewan, ined.” = M. cinchoniifolia.
