(Redirected from Southern beech)

'''Nothofagus''', also known as the 'southern beeches', is a genus of about 35 species of trees and shrubs native to the temperate oceanic to tropical Southern Hemisphere in southern South America (Chile, Argentina) and Australasia (east & southeast Australia, Tasmania, New Zealand, New Guinea and New Caledonia).
In the past they were included in the family Fagaceae, but genetic tests by the Angiosperm Phylogeny Group revealed them to be genetically distinct, and they are now included in a family their own, the 'Nothofagaceae'.

The leaves are toothed or entire, evergreen or deciduous. The fruit is a small, flattened or triangular nut, borne in cupules containing 2-7 nuts.
''Nothofagus'' species are used as food plants by the larva of hepialid moths of the genus ''Aenetus'' including ''A. eximia'' and ''A. virescens''.
