They contain 80–200 large edible seeds, similar to pine nuts, though larger. The male cones are smaller, 4–10 cm (1 + 1 ⁄ 2 –4 in) long, narrow to broad cylindrical, and 1.5–5 cm (1 ⁄ 2 –2 in) broad. The genus is familiar to many people as the genus of the distinctive Chilean pine or monkey-puzzle tree (Araucaria araucana).
The female cone then opens, releasing the seeds which grow to a young seedling. To fertilize the ovum, the male cone releases pollen that is carried in the wind to the female cone. This is pollination. (Male and female cones usually occur on the same plant.) The pollen fertilizes the female gamete (located in the female cone).
The female cones are large and usually woody, 2–60 centimetres (1–24 inches) long, with numerous spirally arranged scales, and two winged seeds on each scale. The male cones are small, 0.5–6 cm (1 ⁄ 4 – 2 + 1 ⁄ 4 in) long, and fall soon after pollination; pollen dispersal is by wind. Seed dispersal is mostly by wind, but some ...
It is usually monoecious with male and female cones on the same tree; the pollen cones are long and slender, up to 20 cm (8 in) long and 1 cm (3 ⁄ 8 in) broad; the seed cones are oval, up to 25 cm (10 in) long and 14–16 cm (5 + 1 ⁄ 2 – 6 + 1 ⁄ 4 in) broad.
