The Latino-barbaric word Olibanum (quasi Oleum Libani), the common name for frankincense in modern commerce, is used in a bull of Pope Benedict IX.
Cedrus Libani, the far-famed Cedar of Lebanon, is a tree which, on account of its beauty, stateliness and strength, has always been a favourite with poets and painters, and which, in the figurative language of prophecy, is frequently employed in the Scriptures as a symbol of power, prosperity and longevity.
The genus Cedrus contains two other species closely allied to C. Libani - Cedrus Deodara, the deodar, or "god tree" of the Himalayas, and Cedrus atlantica, of the Atlas range, North Africa.
C. atlantica, the Atlas cedar, has shorter and denser leaves than C. Libani; the leaves are glaucous, sometimes of a silvery whiteness, and the cones smaller than in the other two forms; its wood also is hard, and more rapid in growth than is that of the ordinary cedar.
In the Mediterranean region occur Cupressus sempervirens, Pinus Pinea (stone pine), species of juniper, Cedrus atlantica, C. Libani, Callitris quadrivalvis, Pinus montana, &c. Several conifers of economic importance are abundant on the Atlantic side of North America - Juniperus virginiana (red cedar, used in the manufacture of lead pencils, and extending as far south as Florida), Taxodium distichum (swamp cypress), Pinus rigida (pitch pine), P. mitis (yellow pine), P. taeda,P. palustris, &c. On the west side of the American continent conifers play a still more striking role; among them are Chamaecyparis nutkaensis, Picea sitchensis, Libocedrus decurrens, Pseudotsuga Douglasii (Douglas fir), Sequoia sempervirens, S.
