Аннотация: The genus Pinus is one of the most widely distributed genera of trees in the Northern Hemisphere. The pines extend from the polar region to the tropics. The pines dominate the natural vegetation in many regions. The genus includes some of the most valuable timber trees in the world, and is readily distinguished frome other plants. For all of these reasons a great deal of information has accumulated about the natural distribution of the pines. This publication summarizes this information in the form of maps, and indicates the sources of information wherever possible
