Nothofagus, also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America and east and southeast Australia, New Zealand, New Guinea, and New Caledonia. The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America.
Nothofagus cunninghamii, commonly known as myrtle beech or Tasmanian myrtle, is the dominant species of cool temperate rainforests in Tasmania and Southern Victoria. It has low fire resistance and grows best in partial shade conditions.
Nothofagus gunnii, the tanglefoot or deciduous beech, is a deciduous shrub or small tree endemic to the highlands of Tasmania, Australia. It was described in 1847 by R.C Gunn N. gunnii is a small woody tree with a shrubby appearance known to grow up to 8 metres (26 ft). It lives only on mountains due to temperature limitations within the Tasmanian maritime climate and mainly grows at altitudes greater than 800 metres (2,600 ft) above sea level. It grows in alpine and sub-alpine regions in the central portions of the island. Though capable of reaching the size of a small tree, it is most common as a thick shrub or woody ground cover, hence its common name of "tanglefoot".
Nothofagus fusca, commonly known as red beech is a species of southern beech, endemic to New Zealand, where it occurs on both the North Island and South Island. Generally it is found on lower hills and inland valley floors where soil is fertile and well drained. In New Zealand the species is called Fuscospora fusca.
Nothofagus menziesii, commonly known as silver beech, is a tree of the southern beech family endemic to New Zealand. Its common name probably comes from the fact that its bark is whitish in colour, particularly in younger specimens. It is found from Thames southwards in the North Island, and throughout the South Island. Silver beech is a forest tree up to 30 m tall. The trunk, which is often buttressed, may be up to 2 m in diameter. The leaves are small, thick and almost round in shape, 6 to 15 mm long and 5 to 15 mm wide with rounded teeth which usually occur in pairs, 1 or 2 hair fringed domatia are found on the underside of each leaf. Its Māori name is tawhai. It grows from low altitudes to the mountains. Nothofagus menziesii was proposed to be renamed Lophozonia menziesii in 2013.
Nothofagus truncata, or hard beech, is a species of tree endemic to New Zealand. Its common name derives from the fact that the timber has a high silica content, making it tough and difficult to saw. Hard beech is a tree up to 30m tall occurring in lowland and lower montane forest from latitude 35°S to 42°30'S, that is, from the north of the North Island southwards to Marlborough and south Westland in the South Island. In Taranaki it forms almost pure stands on the rugged sandstone country there and is partially deciduous, dropping many of its leaves at the end of the winter. N. truncata became known as Fuscospora truncata after 2013 in New Zealand.
Nothofagus solandri, commonly called black beech, is species of tree endemic to New Zealand. Black beech occurs on both the North and the South Island at low elevations up to the mountains. It is also known as Nothofagus solandri var.solandri. In New Zealand the taxon is often called Fuscospora solandri.
Nothofagus alessandrii, the ruil, is a species of plant in the family Nothofagaceae, commonly known as the southern beeches. It is endemic to Chile, occurring chiefly in the Chilean matorral ecoregion. It is threatened by habitat loss. The species is protected within Los Ruiles National Reserve.
Nothofagus alpina, also called rauli or raulí beech is a species of plant in the Nothofagaceae family. A deciduous tree, it grows in Chile and Argentina, it reaches 50 m (160 ft) height and more than 2 meters (6.5 feet) in diameter. Its distribution goes from 35 to 42° South latitude. It is found on the Andes. It tolerates low temperatures and heavy winds. It has a straight and cylindrical trunk with grey bark. N. alpina was proposed to be renamed Lophozonia alpina in 2013.
Nothofagus glauca, commonly known as hualo or roble Maulino, is a species of plant in the family Nothofagaceae. It is a deciduous tree endemic to Chile. It grows from 34° to 37° South latitude. It is a typical tree of the maritime mediterranean-climate Maulino forest of Central Chile, its current range spanning over 330 km from north to south. The species grows on a variety of soils and is mostly found on gentle to steep slopes.
Nothofagus stylosa is a species of plant in the family Nothofagaceae. It is endemic to West Papua (Indonesia). It is a Critically Endangered species threatened by habitat loss.
Nothofagus womersleyi is a species of plant in the family Nothofagaceae. It is endemic to Kebar Valley on the Vogelkop Peninsula in West Papua (Indonesia). It is a Critically Endangered species threatened by habitat loss.
Nothofagus obliqua, commonly known as Patagonian oak, roble, pellín, roble pellín, and hualle in its early state of growth or roble beech, is a deciduous tree from Chile and Argentina. It grows from 33 to 43° south latitude. The northern extent of this tree's range in Chile is considered to be the Vizcachas Mountains and La Campana National Park. N. obliqua was proposed to be renamed Lophozonia obliqua in 2013.
Nothofagus cliffortioides, commonly called mountain beech, is a species of Southern beech tree and is endemic to New Zealand. Mountain beech grows in mountainous regions at high elevations. In New Zealand the taxon is called Fuscospora cliffortioides. Nothofagus cliffortioides occupies a wider range of habitat than any other New Zealand tree species and it shows a corresponding range of life form, seeding habits, regenerative patterns, growth habits, growth rates, stand replacement and mortality patterns.
Nothofagus macrocarpa, commonly known as roble de Santiago or Santiago's oak, is a deciduous tree in the Nothofagaceae family that is endemic to the mountains of central Chile.
Nothofagus brassii is a species of tree in the family Nothofagaceae. It is endemic to New Guinea. It is commonly known as Sagé, sagé hitam, sahé, and kayu sagé, kayu sagé hitam (Indonesian).
Nothofagus carrii is a species of tree in the family Nothofagaceae. It is endemic to New Guinea.
Nothofagus perryi is a species of tree in the family Nothofagaceae. It is endemic to Papua New Guinea. It grows in montane rain forests from 1,500 to 2,500 meters elevation in central and southeastern Papua New Guinea.
Nothofagus pseudoresinosa is a species of tree in the family Nothofagaceae. It is endemic to Papua New Guinea. It grows in montane rain forests from 2,500 to 2,750 meters elevation in central and southeastern Papua New Guinea.
Nothofagus starkenborghiorum is a species of tree in the family Nothofagaceae. It is native to New Guinea and New Britain. It grows in montane rain forests, and occasionally in lowland rain forests.
