It is usually dioecious, with the male and female cones on separate trees, though occasional individuals bear cones of both sexes. The male (pollen) cones are oblong and cucumber-shaped, 4 cm ( 1 + 1 ⁄ 2 in) long at first, expanding to 8–12 cm (3– 4 + 1 ⁄ 2 in) long by 5–6 cm (2– 2 + 1 ⁄ 2 in) broad at pollen release.
The edible large seeds of A. araucana, A. angustifolia and A. bidwillii — also known as Araucaria nuts, [25] and often called, although improperly, pine nuts — are eaten as food, particularly among the Mapuche people of Chile and southwest Argentina, the Kaingang people in Southern Brazil and among Native Australians.

Araucariaceae is a family of conifers with three living genera, Araucaria, Agathis, and Wollemia.While the family's native distribution is now largely confined to the Southern Hemisphere, except for a few species of Agathis in Malesia, it was formerly widespread in the Northern Hemisphere during the Jurassic and Cretaceous periods.
The male cones are slender conic, 5–11 cm (2.0–4.3 in) long and 1–2 cm (0.39–0.79 in) broad and reddish-brown in colour and are lower on the tree than the seed cones.

The hybrid Araucaria angustifolia × araucana is thought to have first arisen "in a plantation forestry environment in Argentina sometime in the late 19th or early 20th century". [19] It is thus not a natural hybrid as there are more than 1000 km between the natural stands of the two species.
