There are two kinds of pines tress here on the island, the Cook Pine and the Norfolk Island Pine.
The difference between the two species is easiest to see in mature trees. Cook pines, as their name A. columnaris implies, have a much tighter, more columnar form, while the mature Norfolk Island pines have a wider, looser branching structure with more open space between the limbs.
These happen to be a mix of both kinds of pines (I think anyway). In upcountry (part way up the dormant volcano where we live) the pine trees are very abundant and give a different look to the island.
