Nothofagus betuloides

Nothofagus betuloides, Magellan's beech or guindo, is a tree native to southern Patagonia. In 1769, Sir Joseph Banks collected a specimen of the tree in Tierra del Fuego during Captain Cook's first voyage. Its occurrence on Hornos Island earns it the distinction of being the southernmost tree on Earth. 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 30 m (98 ft) tall, with a branching reaching appearance. In its natural Patagonian environment, it tolerates cold winters and thrives in the absence of heat, but it is not tolerant of persistent freezing. In the exposed sites of its southerly coastal or Andean distribution, the species grows as a wind formed shrub. Magellan's beech is very long-lived, with specimens reaching ages of 500 to 600 years.
