Araucaria (/ æ r ɔː ˈ k ɛər i ə /; original pronunciation: [a.ɾawˈka.ɾja]) [2] is a genus of evergreen coniferous trees in the family Araucariaceae.While today they are largely confined to the Southern Hemisphere, during the Jurassic and Cretaceous they were globally distributed.
Araucaria angustifolia, the Paraná pine, Brazilian pine or candelabra tree (pinheiro-do-paraná, araucária or pinheiro brasileiro), is a critically endangered species in the conifer genus Araucaria. Although the common names in various languages refer to the species as a "pine", it does not belong in the genus Pinus.
Agathis robusta is a large evergreen tree with a straight cylindrical trunk, which can often reach a height of 30–40 m (98–131 ft), and occasionally 50 m (160 ft). [5] [6] [7] The trunk is usually about 1.2 m (3 ft 11 in) diameter at breast height (DBH), but occasionally may reach 3 m (9.8 ft). [5]
Araucaria bidwillii, commonly known as the bunya pine (/ ˈ b ʌ n j ə /), [4] banya [5] or bunya-bunya, is a large evergreen coniferous tree in the family Araucariaceae which is endemic to Australia. Its natural range is southeast Queensland with two very small, disjunct populations in northeast Queensland's World Heritage listed Wet Tropics.
It is a very large evergreen tree (the tallest in New Guinea, and the tallest species in its family), growing to 50–80 metres (164–262 ft) tall, exceptionally to 90 m (295 ft), with a trunk up to 3 m (10 ft) diameter. The branches are horizontal, produced in whorls of five or six.
The green pine needles give the twisted branches a bottle-brush appearance. The needles of the tree surround the branch to an extent of about one foot near the tip of the limb. [13] The name bristlecone pine refers to the dark purple female cones that bear incurved prickles on their surface. [5] [12] The dark color of these cones helps to ...
A dendrochronology, based on these trees and other bristlecone pine samples, extends back to about 9000 BC, albeit with a single gap of about 500 years. [20] [3] An older bristlecone pine was reportedly discovered by Tom Harlan in 2009, based on a sample core collected in 1957. According to Harlan, the tree was 5,062 years old and still living ...
Araucaria columnaris is a distinctive narrowly conical tree growing up to 60 m (200 ft) tall in its native habit. The trees have a slender, spire-like crown. [3] The shape of young trees strongly resembles A. heterophylla. The bark of the Cook pine peels off in thin paper-like sheets or strips and is rough, grey, and resinous. [3]
