Caryocar nuciferum, the butter-nut of Guiana, is also known as pekea-nut, or – like all other species of Caryocar with edible nuts – "souari-nut" or "sawarri-nut". It is a fruit tree native to northern Brazil, Colombia, Costa Rica, Guyana, Panama, and Venezuela. Pulp of the mesocarp is oily and sticky, holding 1-4 hard, woody, warty stones, with tasty, reniform endocarp, which is eaten raw or roasted, and produces a nondrying edible oil. The wood is durable and used for boat-building. The correctly expressed oil of its nuts produces an effective healing balm.
