PINE, (genus Pinus ), is a genus of about 115 species of evergreen conifers of the pine family (Pinaceae), which is widespread worldwide but is primarily native to northern temperate regions. This, coupled with low sampling and underdeveloped genetic techniques, has made taxonomy difficult to determine. [30][31] In temperate and tropical regions, they are fast-growing softwoods that grow in relatively dense stands, their acidic decaying needles inhibiting the sprouting of competing hardwoods. Cones are light brown and approximately 1 3 (3 7 cm) long. Each fascicle has three needles. The white pine cones have thin scales that whiten at the apex. [18] Pines first appeared during the Early Cretaceous, with the oldest verified fossil of the genus is Pinus yorkshirensis from the Hauterivian-Barremian boundary (131129 million years ago) from the Speeton Clay, England.[19]. Many of the smaller groups of Pinus are composed of closely related species with recent divergence and history of hybridization. Lets look in more detail at some of the most common species of pine trees in the world. In general, this classification emphasized cone, cone scale, seed, and leaf fascicle and sheath morphology, and species in each subsection were usually recognizable by their general appearance. A more recent classification divided the subfamilies and genera based on the consideration of features of ovulate cone anatomy among extant and fossil members of the family. The three-needled gray pine has needles growing 8 to 12 (20 30 cm) long. The pine trees green needles and pale, brown-colored cones measure 2 to 3 (5 7.5 cm) long. The slender, erect pine tree grows 66 to 115 ft. (20 35 m) tall. Conifers are trees that are found primarily in the northern hemisphere and have thin, needle-like leaves to prevent the leaves from dissipating heat. This pine tree species is also classed along with the yellow pines. [2] Older classifications split the genus into three subgenera subgenus Pinus, subgenus Strobus, and subgenus Ducampopinus (pinyon, bristlecone and lacebark pines)[3] based on cone, seed and leaf characteristics. Sugar pines also have the longest cones of any tree in the Pinaceae family. This impressive coulter pine tree also grows giant, spiky cones and has the name the big-cone pine tree. In fact, the coulter pine produces the heaviest cones of any pine tree. The dark green needles are between 1.5 and 3 (4 7 cm). All but two American hard pines belong to this section. These trees are commonly used for decorating gardens and designing landscapes, thriving in temperate zones where the temperature does not fall below -25 C in the winter. Pines in this subgenus have one to five needles per fascicle and one fibrovascular bundle per needle, and the fascicle sheaths are deciduous, except in P. nelsonii, where they are persistent. The small to medium-sized Texas pinyon pine is an evergreen conifer native to southwestern Texas. A number of such introduced species have become naturalized, and some species are considered invasive in some areas[25] and threaten native ecosystems. Distinguishing features of the maritime pine are long yellowish-green stiff needles and conical cones growing 4 to 8 (10 20 cm) long.

They are hardy to USDA zone 8. Several features are used to distinguish the subgenera, sections, and subsections of pines: the number of leaves (needles) per fascicle, whether the fascicle sheaths are deciduous or persistent, the number of fibrovascular bundles per needle (2 in Pinus or 1 in Strobus), the position of the resin ducts in the needles (internal or external), the presence or shape of the seed wings (absent, rudimentary, articulate, and adnate), and the position of the umbo (dorsal or terminal) and presence of a prickle on the scales of the seed cones. The species has good needle retention after being cut and they emit a pleasant citrusy scent. Whilst it's spelt a little differently .

A few are able to sprout after forest fires (e.g. Infrequently used as cover. [15] Recent research using large genetic datasets has clarified these relationships into the groupings we recognize today. Some birds, notably the spotted nutcracker, Clark's nutcracker, and pinyon jay, are of importance in distributing pine seeds to new areas. Pinaceae have evolved a myriad of mechanical and chemical defenses, or a combination of the two, in order to protect themselves against antagonists. In a 1910 publication, the family was divided into two tribes based on the occurrence and type of longshort shoot dimorphism. Cones are long, oval, and prickly and grow up to 2.34 (7 cm). Ponderosa pines are classified as a big tree species and grow up to 235 ft. (72 m) tall. In plantations, individuals usually start to produce female cones when they are 3-4 years old and the production of male cones starts later ( Francis, 1992; Soerianegara and Lemmens, 1993; Oteng-Amako and Brink, 2008).
