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. Agathis australis, commonly known as the kauri, is a coniferous Tree found north of 38°S in the northern districts of New Zealand Plants are living Organisms belonging to the kingdom Plantae. The Order Pinales in the Division Pinophyta, Class Pinopsida comprises all the extant Conifers This order was formerly known as the The Araucariaceae are a very ancient family of Conifers They achieved maximum diversity in the Jurassic and Cretaceous periods when they existed almost Richard Anthony Salisbury FRS ( May 2, 1761 - 1829 was a British Botanist. A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic In Botany, an Evergreen plant is a plant having leaves all year round A tree is a perennial Woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or The Araucariaceae are a very ancient family of Conifers They achieved maximum diversity in the Jurassic and Cretaceous periods when they existed almost While initially widespread during the Jurassic period they are now found only in small areas of the southern hemisphere. The Jurassic is a geologic period and system that extends from about Ma (million years ago to Ma that is from the end of the Triassic to the beginning Southern Hemisphere is the half of a Planet that is South of the Equator —the word hemisphere literally means 'half ball' 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.
The bark is smooth and light grey to grey-brown usually peeling into irregular flakes that become thicker on more mature trees. Bark, also known as periderm is the outermost layer of stems and Roots of Woody plants such as Trees It overlays the Wood and consists 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. A juvenile is an individual Organism that has not yet reached its Adult form Sexual maturity or size In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. For the 2008 British film by Noel Clarke see Adulthood (film. Adult leaves are opposite, elliptical to linear, and very leathery and quite thick. In Mathematics, an ellipse (from the Greek ἔλλειψις literally absence) is a Conic section, the locus of points in a The word linear comes from the Latin word linearis, which means created by lines. Young leaves are often a coppery-red, contrasting markedly with the usually green or glaucous-green foliage of the previous season.
The male pollen cones appear usually only on larger trees after seed cones have appeared. Male (♂ refers to the sex of an organism or part of an organism which produces small mobile Gametes called spermatozoa. Pollen is a fine to coarse powder consisting of microgametophytes ( pollen grains) which produce the male Gametes (sperm cells of A cone (in formal botanical usage Strobilus, plural strobili is an organ on Plants in the division Pinophyta ( Conifers A seed (in some plants referred to as a kernel) is a small embryonic Plant enclosed in a covering called the seed coat usually with some stored The female seed cones usually develop on short lateral branchlets, maturing after two years. Female (♀ is the Sex of an Organism, or a part of an organism which produces ova (egg cells They are normally oval or globe shaped.

Uses
Various species of kauri give diverse resins such as kauri copal and Manilla copal, as well as timber, which is straight-grained and of fine quality. Resin, not to be confused with Rosin, is a Hydrocarbon Secretion of many Plants particularly coniferous trees. Lumber or timber is Wood in any of its stages from felling through readiness for use as structural Material for Construction, or
