'''''Nothofagus''''', also known as the '''southern beeches''', is a genus of about 35 [[species]] of [[tree]]s and [[shrub|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 [[leaf|leaves]] are toothed or entire, [[evergreen]] or [[deciduous]]. The [[fruit]] is a small, flattened or triangular [[nut (fruit)|nut]], borne in cupules containing 2-7 nuts.
''Nothofagus'' species are used as food plants by the [[larva]] of [[Hepialidae|hepialid]] [[moth]]s of the genus ''[[Aenetus]]'' including ''A. eximia'' and ''A. virescens''.
