Description: Ponderosa pine occurs over a wide range--from the Great Plains to the Pacific and from British Columbia to Mexico. Within this range there is great variation in the form and life habits of this tree. It has been long recognized that "regional races" or strains are present. Some of these regional races have been recognized by some botanists as varieties, such as var. scopulorum or var. benthamiana.
