It grows from 35 to 45° South latitude between {{convert|700|and|1,200|m|ft|abbr=on}} above mean sea level. It forms dense forests such as 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 fast-growing and well-distributed species that lives in a range of climatic conditions. DescriptionIt can become a large tree, up to {{convert|45|m|ft|abbr=on}} high and {{convert|1.9|m|ft|abbr=on}} in diameter. One tree, felled by a storm in 1954, reportedly measured {{convert|2.55|m|ft|abbr=on}}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. EtymologyThe 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). The Latin specific epithet dombeyi honours the French botanist Joseph Dombey (1742-1794).[3] UsesCoihue 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 and decay resistant. It is used in furniture, barrels, floors and building. N. dombeyi has been introduced as an ornamental tree for parks and large gardens in the British Isles[4] where it has gained the Royal Horticultural Society’s Award of Garden Merit.[5][6] It has also been introduced to the North Pacific Coast of the United States.[7]Gallery==References== 1. ^{{cite web |title=BSBI List 2007 |publisher=Botanical Society of Britain and Ireland |url=http://www.bsbi.org.uk/BSBIList2007.xls |format=xls |archive-url=https://www.webcitation.org/6VqJ46atN?url=http://www.bsbi.org.uk/BSBIList2007.xls |archive-date=2015-01-25 |accessdate=2014-10-17 |deadurl=yes |df= }} 2. ^{{PLANTS|id=NODO|taxon=Nothofagus dombeyi|accessdate=29 January 2016}} 3. ^{{cite book |last=Harrison |first=Lorraine |title=RHS Latin for Gardeners |year=2012 |publisher=Mitchell Beazley |location=United Kingdom |isbn=184533731X }} 4. ^TWFS List of Accepted Plants of the British Isles 2007 5. ^{{cite web | url= https://www.rhs.org.uk/Plants/11561/i-Nothofagus-dombeyi-i/Details| title = RHS Plantfinder - Nothofagus dombeyi | accessdate= 13 April 2018}} 6. ^{{cite web | url= https://www.rhs.org.uk/plants/pdfs/agm-lists/agm-ornamentals.pdf | title = AGM Plants - Ornamental | date = July 2017 | page = 69 | publisher = Royal Horticultural Society | accessdate = 13 April 2018}} 7. ^{{cite web | url=http://www.seattle.gov/parks/proparks/projects/ArboretumReport.pdf | title=Nothofagus dombeyi in Washington Park Arboretum}} Further reading
