Any of various evergreen or deciduous trees of the genus Nothofagus of South America and Australasia, having alternate leaves and small nut-bearing fruits.
[From the fact that native ranges of the trees are confined to the Southern Hemisphere or perhaps translation of New Latin Nothofāgus, genus name (from Greek nothos, bastard, false + Latin fāgus, beech), taken as if from Greek notos, south wind, south + Latin fāgus.]
