Amomyrtus luma

Amomyrtus luma, known as luma, is a species of tree in the family Myrtaceae. It is native to Chile and Argentina. It grows from Colchagua to Aysen (34 to 45°S). This species occurs in rainforests, near streams, and in other moist sites.
Description.
Luma is an evergreen tree that measures up to 25 m (80 ft) tall and up to 50 cm (25 in) in diameter, with smooth bark, decorticant, reddish to brown. The leaves are opposite, in an oval to oblong shape, with an acute apex that ends in a pointed end up to 1 mm long. The petioles are hairy, 2–4 mm long. New shoots are hairy, which distinguishes it from Amomyrtus meli, a species that it strongly resembles. The flowers are hermaphroditic, with 5 fused sepals and 5 free white petals about 4 mm long. The stamens are numerous (30-45) and 4–5 mm long. The fruit is a black to purplish-black berry when mature, 1-1.5 cm in diameter, generally with 3 seeds, about 3-4.5 mm.
Uses.
The fruits, which are called "cauchaos," are edible and used to make marmalade. The wood is extremely hard and resistant and is used as firewood. It has been planted in Spain.
Etymology.
The name "Amomyrtus" comes from the Greek "Amos" (fragrant) and the family name "Myrtus", and "Luma" is the Mapuche name for the tree.
