The bark is gray-brown or reddish brown. Young leaves are needle-like, 3-6 mm long, while older branches are scaly, about 1.5 mm long. The fruit is blackish blue with white powder, 5 mm in diameter, 3-6 mm long. The wood is homogenous, easy to sharpen, and fragrant, and is used for pencils, hence the name. It is also used for crafts, barrels, plywood, etc. The oil from the wood is used as zealand oil for microscopes, as a soap fragrance, as a fragrance fixative, and as an adulterant. It is found in the mountainous areas on the east side of the Rocky Mountains in western North America, from Hudson Bay through New Mexico and Texas to Florida, and is exported in large quantities as pencil material. In Japan, there are many horticultural varieties, which are planted in gardens. Propagation is usually by cuttings, but it can also be propagated from seed.
