Discussion	[This taxon does not have a floristic treatment in Flora of Oregon.]	Primarily Northern Hemisphere. 10 genera; 6 genera treated in Flora. Of major economic importance, the members of this family are used as ornamentals and as a source of turpentine, tars, essential oils, and food. Additionally, most of the world’s softwood timber is harvested from Pinaceae species. Primarily a Northern Hemisphere family, only one species, Pinus merkusii, is found south of the equator.
