Caryocar nuciferum

Caryocar nuciferum, commonly known as the souari nut or butternut, is a tropical tree species belonging to the family Caryocaraceae. It is native to the northern regions of South America, including the Amazon rainforest. This species is renowned for its large, edible nuts, which are a source of food and oil for both local populations and international markets. The tree is also valued for its durable wood and ornamental qualities.

Caryocar nuciferum trees can reach heights of up to 35 meters. They possess a broad, spreading canopy that provides significant shade. The leaves are large, glossy, and dark green, arranged in a whorled pattern. The flowers are hermaphroditic, featuring five white or pink petals and a multitude of stamens, making them quite conspicuous. The fruit of Caryocar nuciferum is a large, spherical drupe that contains one to three seeds. These seeds are the souari nuts, which are encased in a hard shell.
