The Incense Cedar
Incense Cedar (Libocedrus decurrens), already noticed among the Yosemite trees, is quite generally distributed throughout the pine belt without exclusively occupying any considerable area, or even making extensive groves. On the warmer mountain slopes it ascends to about 5000 feet, and reaches the climate most congenial to it at a height of about 4000 feet, growing vigorously at this elevation in all kinds of soil and, in particular, it is capable of enduring more moisture about its roots than any of its companions excepting only the sequoia.
Casting your eye over the general forest from some ridge-top you can identify it by the color alone of its spiry summits, a warm yellow-green. In its youth up to the age of seventy or eighty years, none of its companions forms so strictly tapered a cone from top to bottom. As it becomes older it oftentimes grows strikingly irregular and picturesque. Large branches push out at right angles to the trunk, forming stubborn elbows and shoot up parallel with the axis. Very old trees are usually dead at the top. The flat fragrant plumes are exceedingly beautiful: no waving fern-frond is finer in form and texture. In its prime the whole tree is thatched with them, but if you would see the libocedrus in all its glory you must go to the woods in midwinter when it is laden with myriads of yellow flowers about the size of wheat grains, forming a noble illustration of Nature’s immortal virility and vigor. The mature cones, about three-fourths of an inch long, born on the ends of the plumy branchlets, serve to enrich still more the surpassing beauty of this winter-blooming tree-goldenrod.
