 nuts are consumed largely as food. There are several species of pines yielding edible nuts on the Pacific coast of the United States and as far east as Colorado and New Mexico. These nuts are articles of considerable importance in the commerce of many of the cities of California. The principal specimens of pine which yield edible nuts are Pinus monophylla Torr. and Frem., Pinus edulis Engelm., Pinus sabiniana Dougl. The refuse is usually less than 50 percent of the total weight of the nut.
