Araucaria araucana (Molina) K. Koch
Araucaria imbricata Pav.
The monkey-puzzle tree is native to south central Chile and west central Argentina. In these locations it is found in the Andes Mountains, usually above 3281' (1 km). It is not found in the wild in North America. It is named because the shape and curl of the branches resemble monkey’s tails.
Identification: Trees are evergreens, 98-131' (30-40 m) tall and 3-5' (1-1.5 m) around, and conical in shape. Bark is gray-brown, with rings left from older leaves. Branches form whorls of five, emerging almost horizontally from the trunk. Leaves are scale-like, with sharp tips. They cover every branch and even the trunk. Leaves are 1-1¾" (3-5 cm) long and ¼-⅞" (8-25 mm) wide. Male cones are yellowish-brown, 2½-6" (7-15 cm) long × 1¾" (5 cm) wide. Female cones are round, dark brown, 4-7" (10-18 cm) long × 3-6" (8-15 cm) wide. The individual scales of both cones have narrow, sharp tips. Don’t confuse this with the related and similar-appearing Norfolk pine.
