Nothofagus dombeyi (Coihue) is a tree species that inhabits the Andes of the Argentine Patagonia and central Chile, It grows from 35 to 45° South latitude between 700 and 1,200 m (2300-4000 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 a well distributed species, it lives in several climatic conditions. It is a fast-growing species
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 (8.36 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.
Coihue timber is considered excellent. In Argentina its exploitation is limited by the presence of the best forests within national parks. The wood is bright grayish white; the heartwood is a pale pink-white, which darkens after cut. Its texture is very fine and makes it easy to work with. It has a beautiful engraving, is semi-heavy, hard, durable, easy-to-work and decay resistant. It is used in furniture, barrels, floors and building. It has been introduced as ornamental in the British Islands and also in the North Pacific Coast of the United States.
The name of the tree is often spelled coigüe (reflecting the common pronunciation with an epenthetic g). Other related trees named coihue are the Coihue de Magallanes (Nothofagus betuloides), and the Coihue de Chiloé (Nothofagus nitida).
