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.
Western white pine is a large tree, regularly growing to 30–50 metres (98–164 ft) tall. It is a member of the white pine group, Pinus subgenus Strobus , and like all members of that group, the leaves ('needles') are in fascicles (bundles) of five, [ 5 ] with a deciduous sheath.
The root system is extensive. A tiny seedling may quickly send a taproot down 60 centimeters (24 in) seeking moisture and nutrients. A mature tree may have roots extending 75 meters (246 ft). Exposed trees battered by coastal winds are often twisted into beautiful sculptural shapes resembling large bonsai, and rarely exceed 12 m (39 ft) tall.
The stone pine is a coniferous evergreen tree that can exceed 25 metres (80 feet) in height, but 12–20 m (40–65 ft) is more typical. In youth, it is a bushy globe, in mid-age an umbrella canopy on a thick trunk, and, in maturity, a broad and flat crown over 8 m (26 ft) in width. [ 2 ]
