Flowers/fruit: Monoecious. Fruit a woody cone; very short to no stalk; 3" to 6" long; reddish-brown; each scale armed with a short, sharp spine.

Bark: Dark brown to black on younger trees; older trees have large, thick plates, orange to cinnamon-red, separated by deep furrows; inner bark has vanilla smell.

Wood: Very important; sapwood white to yellow; heartwood yellow to light brown; growth rings distinct; used for lumber, millwork, and railroad ties.

General: Native to mountainous areas in southern two-thirds of Utah and throughout the West. Normal growth rate is relatively slow. Resists fires with thick bark. Drought resistant. Shade intolerant.
