Caryocar (souari trees) is a genus of flowering plants, in the South American family Caryocaraceae described as a genus by Linnaeus in 1771. It is native primarily to South America with a few species extending into Central America and the West Indies. Caryocar consists of trees that yield a strong timber. Some of the species within the genus Caryocar have edible fruits, called souari-nuts or sawarri-nuts. The most well-known species is probably the Pekea-nut (C. nuciferum). In Brazil the Pequi (C. brasiliense) is most popular; it has a variety of uses, not the least among them being the production of pequi oil. Furthermore, some species are used by indigenous peoples to produce poisons for hunting.
