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).
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.
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.
It is usually dioecious, with the male and female cones on separate trees. The male (pollen) cones are oblong, 6 cm ( 2 + 1 ⁄ 2 in) long at first, expanding to 10–18 cm (4–7 in) long by 15–25 mm ( 9 ⁄ 16 –1 in) broad at pollen release.
Araucaria heterophylla (synonym A. excelsa) is a species of conifer. As its vernacular name Norfolk Island pine (or Norfolk pine ) implies, the tree is endemic to Norfolk Island , an external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia .
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. [3] Seedlings appear to be slow-growing [ 3 ] and mature trees are extremely long-lived; some of the older individuals today are estimated to be between 500 and 1,000 ...
Agathis, commonly known as kauri or dammara, is a genus of evergreen coniferous trees, native to Australasia and Southeast Asia.It is one of three extant genera in the family Araucariaceae, alongside Wollemia and Araucaria (being more closely related to the former).
Shelled European pine nuts (Pinus pinea) Araucaria angustifolia seeds. Conifer nuts are the edible seeds of conifers, which includes most notably pine nuts (family Pinaceae) and Araucaria nuts (family Araucariaceae). "Many pine species bear edible nuts: the best known is the Mediterranean stone pine, Pinus pinea.
