The genus '''''Agathis''''', commonly known as '''kauri''' or '''dammar''', forms a relatively small group of 21 species of [[evergreen]] [[tree]]s in the family [[Araucariaceae]], characteristically with very large trunks and little or no branching for some way up. Young trees are normally conical in shape, only upon maturity does the crown become more rounded or irregularly shaped.

The [[bark]] is smooth and light grey to grey-brown usually peeling into irregular flakes that become thicker on more mature trees. The branch structure is often horizontal or when larger, becoming more ascending. The lowest branches often leave circular branch scars as they fall off from the lower trunk.
The [[juvenile (organism)|juvenile]] [[leaves]] in all species are larger than the [[adult]], more or less acute, varying among the species from ovate to lanceolate. Adult leaves are opposite, [[elliptical]] to [[linear]], and very leathery and quite thick. Young leaves are often a coppery-red, contrasting markedly with the usually green or glaucous-green foliage of the previous season.
The [[male]] [[pollen]] [[Conifer cone|cones]] appear usually only on larger trees after [[seed]] cones have appeared. The [[female]] seed cones usually develop on short lateral branchlets, maturing after two years. They are normally oval or [[globe]] shaped.
The trees are the source of [[Dammar Gum]].
Seeds of some species are attacked by the [[caterpillars]] of one of the most primitive of all living moths, [[Agathiphaga]].

[[Image:Te_Matua_Ngahere.jpg|thumb|[[Te Matua Ngahere]], a kauri in [[Waipoua Forest]], is the second largest tree in New Zealand. The largest tree, [[Tāne Mahuta]], is nearby.]]
==Uses==
Various species of kauri give diverse [[resin]]s such as kauri copal and Manilla copal, as well as [[timber]], which is straight-grained and of fine quality.
The wood is commonly used in the manufacture of budget-priced [[guitar]]s. It is also used for some [[Go (board game)|Go]] boards ([[goban]]).
