Nothofagus dombeyi, Dombey's beech,
The shadow produced by stands of Nothofagus dombeyi is an important factor that keeps the air around streams cool and with relatively low daily temperature variations.[4]
Description
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 (leathery) 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, measuring less than 5 mm, are insignificant. The fruit is a triangular nut measuring about 4–7 mm.
Etymology
The name of the tree is often spelled coigüe (reflecting the common Spanish pronunciation with an epenthetic g). Other related trees named coihue are the Coihue de Magallanes (Nothofagus betuloides), and the Coihue de Chiloé (Nothofagus nitida).
The Latin specific epithet dombeyi honours the French botanist Joseph Dombey (1742-1794).[5]
Distribution and habitat
Nothofagus dombeyi is found 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 such as those found in the
Uses
Coihue
Nothofagus dombeyi has been introduced as an ornamental tree for parks and large gardens in the British Isles[6] where it has gained the Royal Horticultural Society's Award of Garden Merit.[7][8] It has also been introduced to the North Pacific Coast of the United States.[9] It requires an acid pH soil which is fertile and reliably moist. Young plants need shelter from cold winds; however mature specimens are hardy down to −15 °C (5 °F).[7]
