Abstract
In 1972 the author described the new species Acioa edulis (Chrysobalanaceae) to name the Castanha de cutia, a plant which is economically important because of its edible fruit. The original description was based on fruiting material only. Recently collected flowering material has shown that the original generic assignment was incorrect, and so it is now transferred to Couepia the correct genus, and the flowers are described for the first time.
