Cryptocarya alba, the peumo or Chilean acorn, is an evergreen tree[1] that grows in Chile and Argentina from 33 to 40° southern latitude.

An associate tree is the endangered Chilean Wine Palm, Jubaea chilensis,[2] which species prehistorically had a much wider range.

The trunk is straight and hardly twisted; brown-grayish cork cambium, relatively smooth, with few cracks and detachable scales when old.

The flowers are in dense bunches, greenish yellow and three to four mm long; hermaphrodite, they have six fleshy uneven and hairy petals.

It produces edible fruits red-colored, called "peumos", which contain large heavy seeds, which germinate easily.
