Araucaria heterophylla

Not far from the Lodge at Koele in Lanai is a road that follows the ridgeline of the island's mountains. When the road first begins to climb in altitude (ultimately reaching 3000'+) you pass a modest cemetery for the local residents of nearby Lanai City (population 3,164).  Flanking the cemetery are Cook's Pine, or Araucaria columnaris.   At first glance, I would have assumed they were Araucaria heterophylla, or Norfolk Island Pine.  Indeed they are quite similar, though local lore states that only one Norfolk Island Pine stands in Lanai, and it is located in the front yard of the Lodge.

 

As you can see, this specimen is more than a little majestic.   Both species of Araucaria are quite similar.  There's a great site that details the differences among A. heterophylla and A. columnaris here.

 

The plaque below indicates this tree as Norfolk Island Pine (coincidentally enough, Captain Cook named Norfolk Island himself, and consequently the Norfolk Island Pine.  When A. columnaris was deemed a different species, the common name was based on Cook.).

Both species are common enough in Hawaii and are often used to flank roadways and orchards.  You can see a shot of them along the pineapple farms of Oahu in a NYPAOS post here.  While Araucaria is in the pine order, Pinales, it is not a member of the pine family, Pinaceae.
