Pine is the common name for species of the genus Pinus, a group of coniferous gymnosperms in the family Pinaceae characterized by needle-like evergreen leaves borne in fascicles, woody seed cones, and resin canals. Members of Pinus exhibit secondary growth with distinct earlywood–latewood transitions, produce winged seeds typically dispersed by wind or animals, and synthesize terpenoid-rich oleoresins involved in defense and xylem protection. The genus is ecologically dominant in many temperate and boreal forests, shows diverse adaptations to fire and nutrient-poor soils, and is widely used as a model for studies of conifer physiology, forest ecology, and long-lived perennial life histories.
