    Incense-cedar (Libocedrus decurrens) is the only species from  the small genus Libocedrus that is native to the United States.  Increasingly, it is placed in a segregate genus Calocedrus. Incense-cedar  grows with several conifer species on a variety of soils, generally on  western slopes where summer conditions are dry. It is long-lived and grows  slowly. Most of the top-grade lumber is used for the manufacture of  pencils and exterior siding.
