Ar'auca'ria, a genus of cone-bearing trees belonging to the southern hemisphere. They are lofty evergreen trees, with large, stiff, flattened leaves, generally overlapping along the branches, like the shingles on a roof. The spreading branches are in whorls around the trunk and bear large cones, each scale covering a single large seed, which is edible when roasted. The Moreton Bay pine of New South Wales supplies a valuable timber used in house and boat building, in making furniture and in other carpenter work. Another species, the Norfolk Island pine, abounds in several of the South Sea Islands, where it attains a height of 220 feet, with a circumference of thirty feet. It is described as one of the most beautiful of trees. Its foliage is light and graceful, quite unlike that of the Chile pine, which is stiff and formal in appearance. Its timber is of some value, being white, tough and close-grained.
