It may here be remarked that the name "European frankincense" is applied to Pinus Taeda, and to the resinous exudation ("Burgundy pitch") of the Norwegian spruce firs (Abies excelsa).
P. Taeda, the " loblolly pine " of the backwoodsman, a tall tree with straight trunk and spreading top, covers great tracts of the " pine-barrens " of the southern states, but also frequently spreads over deserted arable lands that have been impoverished by long and bad farming; hence the woodsmen call it the " old-field " pine, while, from the fragrance of its abundant resin, it is also known as the frankincense pine.
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.
In the United States the turpentineyielding pines are the swamp pine, P. australis, and the loblolly, P. Taeda, both inhabiting North and South Carolina, Georgia and Alabama.
