The genus Agathis, commonly known as kauri or dammar forms a relatively small group of 21 species of evergreen trees in the family Araucariaceae, characteristically with very large trunks and little or no branching for some way up. Young trees are normally quite 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 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 female is one half of a heterogamous reproduction system, where seed cones usually develop on short lateral branchlets, maturing after two years.
