Two new species of Nasa (Loasaceae) from Andean South America

T. HENNING, M. WEIGEND

Abstract


Two new species of the South American Genus Nasa, namely Nasa sanchezii and N. urubambensis  are described as new to science. Both species are found in the Peruvian Andes. Nasa sanchezii occurs in the north, in the Amotape-Huancabamba zone, a diversity hotspot in general and the main center of diversity for the genus Nasa in particular. Nasa urubambensis is found in the southern Peruvian Andes (Department Cusco) an important secondary center of diversity of the genus. Both species are here formally described and notes on the distribution, habitat and affinities are given. A distribution map for both taxa and line drawings for each species are provided.
