Nothofagus dombeyi (Dombey's beech,coigue,coihue or coigüe (from koywe in Mapuche language)) is a tree species native to southern Chile and the Andean parts of Argentine Patagonia. It grows from 35 to 45° South latitude between 700 and 1,200 m (2,300 and 3,900 ft) above mean sea level. It forms dense forests, like those found in the Los Alerces and Nahuel Huapi national parks. It thrives in low hills with gentle slopes, being very demanding of water and soil; the largest forests are found on the slopes looking south, and the healthier specimens tend to grow on the banks of rivers and lakes. It sometimes forms mixed forests with Araucaria araucana (monkey-puzzle) trees, for example in the Villarrica National Park in Chile. It is fast-growing and well-distributed species that lives in several climatic conditions.
It can become a large tree, up to 45 m (148 ft) high and 1.9 m (6.2 ft) in diameter. One tree, felled by a storm in 1954, reportedly measured 2.55 m (8.4 ft)in diameter at the height of a man's chest and a total volume, including the branches, of 87 m³.
The coihue usually has elegant branches which are flattened horizontally. The leaves are evergreen, small (25–40 mm long and 10–16 mm wide), thick, coriaceous and lustrous, dark green, with toothed borders and an acute apex; they have a very small, rounded and rhomb-shaped petiole. The tree is hermaphroditic; male and female flowers are grouped in the same tree, and pollen is spread by wind action. The flowers are little visible because they are green and measure less than 5 mm. The fruit is a triangular nut that measures about 4–7 mm.
