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.

The almond is native to Iran, from northwestern Saudi Arabia, north through western Jordan, Israel, Lebanon, western Syria, to southern Turkey. It is a small deciduous tree, growing to between 4 and 10 meters in height, with a trunk of up to 30 centimeters in diameter. The young shoots are green at first, becoming purplish where exposed to sunlight, then grey in their second year. The leaves are 1 cm long and 1.2&ndash;4 cm broad, with a serrated margin and a 2.5 cm petiole. The flowers are white or pale pink, 3&ndash;5 cm diameter with five petals, produced singly or in pairs before the leaves in early spring. The fruit is a drupe 3.5&ndash;6 cm long, with a downy outer coat. The outer covering or exocarp, (fleshy in other members of Prunus such as the plum and cherry), is instead a leathery grey-green coating called the hull, which contains inside a hard shell, and the edible seed, commonly called a nut in culinary terms. Generally, one seed is present, but occasionally there are two. In botanical terms, an almond is not a true nut. The reticulated hard woody shell (like the outside of a peach pit) surrounding the edible seed is called the endocarp. The fruit is mature in the autumn, 7&ndash;8 months after flowering.

The genus is native to temperate regions of the Northern Hemisphere, growing primarily in early successional habitats. It is most diverse taxonomically in North America, especially in the northern United States and southern Canada, and is native to every state of the United States except Hawaii. Two species also occur in Asia, and one in Europe. These plants are valued horticulturally, and their fruits are important to wildlife.
