Pines are evergreen, coniferous resinous trees (rarely shrubs) growing 3-80 meters tall, with the majority of species reaching 15-45 meters tall. The genus is the largest in the family Pinaceae, and is considered important both ecologically and economically. Pines are known for their long, needle-shaped leaves and for their cones, which are the reproductive structures of the tree. This article provides a comprehensive list of Pinus species, highlighting their significant diversity and distribution.
