The trees can live up to 450 years and grow to a height of 60 metres. The bark is rough, splits naturally, and peels easily.The leaves on young trees are awl-shaped, 1-2 cm long, about 2 mm thick at the base, and scale-like, incurved, 1-2 cm long and 4 mm broad on mature trees. The cones are ovoid, 8-10 cm long and 6-8 cm diameter, and take about 18 months to mature. They disintegrate at maturity to release the nut-like edible seeds.
