Pine trees are all evergreens and possess needles as leaves and cones as part of their reproductive system. All pines are resinous Coniferous trees. Some Pine species grow as shrubs instead of trees. Pine trees can be found on all continents around the world except Antarctica.

List of Pine tree species organized by taxonomic classification

List of Pine Tree Species in Alphabetical order further below on this page;

Pine trees can be divided into two groups according to branch set production;

1. Uninodal, producing one whorl of branches each year, from buds at the tip of the current year's main trunk shoot.
2. Multinodal, producing two or more whorls of branches per year.

Pine tree branches are produced during upward growth of the main steam shoot, braches appearing in regular "pseudo whorls", (a very tight spiral but appearing like a set of branches all branching out from the same height on the main trunk). Interestingly, the spiral arrangement of branches, needles, and cone scales resemble Fibonacci number ratios (following the numeric golden rule in nature). On Pine trees, the new shoots of branches are sometimes called "candles". The "Candles" consist of a bud scale either brown or cream color, pyramidal in shape pointing upwards, covering a wad of new needles surrounding the branch bud. The bud scale eventually falls off and the needles spread outward.

The bark on most Pine trees is typically layers of scaly flakes, thick and cracked, brown in color and scented by the resin. Some Pine tree species have a thin flaky bark, when on close observation chunks of bark can be seen just hanging on or flaking off.
