| Summary: | <em>Nasa </em>is the largest genera in the Loasaceae family and it is particularly speciose in the Amotape-Huancabamba Zone of northern Peru. <em>Nasa</em> ser. <em>Carunculatae </em>is a group of four species, three of them endemic to the Amotape- Huancabamba Zone. Species in this group are characterized by their shrubby habit, deciduous leaves, and typical tilt-revolving flowers with white to greenish petals. In this work, we describe a new species of <em>Nasa </em>ser. <em>Carunculatae </em>from the southern limit of Amotape-Huancabamba area, La Libertad, Peru. The species differs from others in having much smaller and notably narrower leaves. Unlike all the other species of ser. <em>Carunculatae</em>, the entire distal portion of the stem is densely glandular. It is apparently most closely related to <em>Nasa </em>carunculata, a species known from inter-Andean valleys of Ancash and Ayacucho. |
