Digger Pine TreeThe Digger Pine (P. Sabiniana, Dougl. ), growing only on the sun-baked foothills of western California, deserves mention here on account of its peculiar sparse foliage, pale, bluish green, and 8 to 1.2 inches long, that in no wise conceals the angular limbs, and the great cones, 6 to 10 inches long, which fairly load the tree, and are carried for several years. The thickened scales protrude separately as two-edged, thick projections that end in a beak shaped like a shark's tooth.
The Digger Indians once gathered the seeds of this pine for food. The nuts are as big as lima beans, and rich in oils and other food elements.
