An illustration of an Agathis branch. The genus Agathis, commonly known as kauri or dammar, is a relatively small genus of 21 species of evergreen trees in the very ancient Araucariaceae family of conifers. While initially widespread during the Jurassic period they are now found only in small areas of the southern hemisphere. The trees have characteristically 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.
