Nothofagus betuloides, Magellan's beech or guindo, is a tree native to southern Patagonia.
Nothofagus betuloides grows from southern Chile and southern Argentina (40°S) to Tierra del Fuego (56°S). It is found from sea level to 500 m (1,600 ft) above mean sea level. One specimen growing near the southeastern corner of Hornos Island (Cape Horn) was identified in 2019 as the southernmost tree in the world.
It is an evergreen tree up to 25 m (82 ft) tall, with a columnar appearance. In its natural environment, it tolerates cold winters and absence of heat in summer. Specimens from the southern forests resist temperatures down to −20 °C (−4 °F).
It succeeds in Scotland. Trees planted in the Faroe Islands, which were imported directly from its southernmost distribution in Tierra del Fuego, have turned out to be very hardy.
The wood has beautiful marks, and is pinkish, hard, and semiheavy; it is used in furniture and construction.
