Plants in the Araucariaceae are found in the Southern Hemisphere. They constitute two genera and about 30 species. The most famous trees in this family are the cook pines (found originally from Cook island) and the Norfolk Island pine (found on Norfolk island). Both of these trees are from islands off the coast of Australia.
On the islands of Hawaii, both Cook pines and Norfolk island pines are found along ridge tops and planted in large groves. Originally they were brought in to act as masts for sailing boats, but it turns out mature trees don't work all that well for strong masts.
These plants are both monecious and dioceous. The leaves are opposite, although sometimes spiraling around the stem.
