Agathis spathulata (New Guinea Kauri) is a species of Agathis native to the highlands of eastern Papua New Guinea, occurring at altitudes of 900-1980 m. Although long known, it has only relatively recently (1980) been distinguished from A. robusta, being described first as a subspecies of it, Agathis robusta subsp. nesophila Whitm., and subsequently separated as a distinct species A. spathulata in 1988. It is threatened by habitat loss.
It is a large evergreen tree growing up to 60 m tall. The leaves are in decussate opposite pairs, 7-10 cm long and 18-30 mm broad on mature trees, up to 13 cm long and 45 mm broad on young trees. The cones are oval, 8.5-10 cm long and 6.5-7.5 cm diameter, and disintegrate at maturity to release the winged seeds.
