[AS. pin, from L. pinus.] The name of a family of cone-bearing trees, found in Europe, Asia, and America, growing chiefly in mountainous or other exposed situations. Their leaves are needle-shaped, growing m clusters or in pairs, and surrounded with little scales at their base. The most important species is the American white pine, widely used in carpentry from the softness and ease of working of its timber. Other species are the red Canadian pine, the yellow pine, the nut pine, the sugar pine, and the pitch pine. Under this name are sometimes included spruces, firs, larches, and true cedars (q. v.).
