Agathis lanceolata aka Serpentine Forest Kauri

Agathis lanceolata has the common name Koghis kauri. It belongs to the Araucariaceae family. This tree stays green all year. It comes from New Caledonia in the Pacific. There, it grows in a wet tropical climate. In its home forests, it rises above the canopy. It grows in dense, damp rainforest on ultramafic rock. Its known wild range is small, with gaps between patches.

The tree can reach 131 feet (40 metres) tall. This is a reported maximum, not a garden size range. Its dense crown has an uneven shape. The trunk may have no branches for 49 feet (15 metres). It keeps its leaves all year. The species account gives few other facts about the leaves. Wind carries its pollen, but the account gives no flowering season. The source's specimen caption names male and female cones.

Light needs change as the tree grows. Young trees need the shade and shelter found in woods. Older trees grow well in sites with direct sun. Fresh seed is one way to grow new plants. Do not let the seed dry out. In normal storage, it lasts little more than two months. It needs no treatment before sowing. Set the wing upright and bury about two-thirds of the seed. Seeds can start to sprout within six days. The source reports that 90–100 percent sprout within ten days. New plants can also grow from cuttings. Use the main shoots or shoots that grow from the trunk.

Koghis kauri once provided New Caledonia's main softwood timber. People cut trees faster than new ones could replace them. Too few trees now remain to sustain that former trade. People also gather resin from wild trunks. The tree yields large amounts of pale yellow, scented resin. Some light passes through this resin, known as kauri or dammar. Records note its use on wounds and ulcers to fight germs. The source lists the seeds as edible. It reports no known hazards. Yet it gives no detailed review of safety.

Useful Tropical Plants cites a 2011 IUCN review. That review gave the tree a status of Vulnerable. Both its habitat area and wild tree numbers were shrinking. The account reports no group above 1,000 mature trees. Heavy past logging and gaps in its range shape its needs for protection. Records cover its forest role and past timber use well. The supplied facts do not set frost limits or garden sizes.
