Abstract
Aiouea Aubl. is a genus of the Lauraceae family restricted to the Neotropics. Most species occur in tropical and mountainous forests of Central America, the Andes, and Brazil, from sea level to 2800 m. Recent field investigations in southeastern Brazil, as well as my study of 237 herbarium specimens, revealed a new species that I describe here as Aiouea albopunctata Brotto. The new species is mainly characterized by its whitish-punctuated fruits – hence the name – and is restricted to the mountains of eastern Brazil at altitudes between 600 and 1700 m. I provide a complete description of the new species, including illustrations, a distribution map, and key features distinguishing it from other species in the Atlantic Rain Forest.
