The Pines Pinus is comprised of trees, occasionally shrubs, which are evergreen, highly resinous, and monoecious. This genus is more important in timber-production than any other conifer genus.
Pine trees share many characteristics.
One species, Pinus merkusii , occurring in Sumatra, is the only pine species that naturally crosses the equator into the Southern Hemisphere. However, several species, especially loblolly pine, have been planted in the Southern Hemisphere.
