Araucaria angustifolia, also known as the Brazilian Pine, Candelabra Tree, or Parana Pine, is a critically endangered coniferous species native to Southern Brazil and parts of Argentina and Paraguay. Despite its common name of "pine", it does not belong in the genus Pinus. This evergreen tree can grow up to 130 ft tall and has thick, tough, triangular leaves that persist for 10-15 years. The seeds, similar to large pine nuts, are edible and are extensively harvested in southern Brazil, but humans eating them can reduce propagation and threaten the species' regeneration. The tree is popular in subtropical gardens for its unusual thick, reptilian branches that have a very symmetrical appearance. Araucaria angustifolia requires a subtropical climate with abundant rainfall and tolerates occasional frosts down to about -4 - 5°F. It is also widely used in folk medicine and has antiviral properties. Unfortunately, the species has lost an estimated 97% of its habitat to logging, agriculture, and silviculture, and as a result, is now critically endangered.
