Araucaria heterophylla (formerly A. excelsa)
NORFOLK ISLAND PINE
Norfolk Island pine, native to Norfolk Island east of Australia, faces risk of extinction in the wild due to its small range (Norfolk Island is less than 14 square miles), plus decline in extent and quality of habitat. Remaining stands are protected within Norfolk Island National Park.
Norfolk Island pine is tall, to 150 feet (though the ones I've seen in the San Francisco Bay Area are nowhere near that tall), symmetrical, pyramidal, with tiered branches. It is salt and wind tolerant. Norfolk Island pine is a popular ornamental in Australia, New Zealand, Hawaii and California, and widely planted in subtropical climates around the world. The wood is used for turning and crafts by Hawaiian artisans.
Unlike seeds of bunya-bunya, the seeds of Norfolk Island pine are not edible. The seed cones are squat and round, about four inches in diameter, and take about 18 months to mature. They disintegrate at maturity, not posing the dangers of bunya-bunya cones.
Leaves are densely spiraled and awl-shaped, but not sharp.
Pollen cones are long and cylindrical.
