Caryodendron orinocense, commonly known as cacay, inchi or orinoconut, is an evergreen tree belonging to the family Euphorbiaceae. This species of flowering plant is indigenous to the north-west of South America, particularly from the drainage basins of the Orinoco and Amazon rivers located in Colombia, Venezuela, Ecuador, Peru and Brazil. Originally described by Hermann Karsten in 1858, the cacay tree distinguishes itself by its dense and leafy top, as well as its production of fruits, each one containing three edible nuts. Cacay is notable for the oil extracted from its nuts, which is edible and is also used in cosmetics.
