Wikipedia Abstract

Pinus rigida, the pitch pine, is a small-to-medium-sized (6–30 m (20–98 ft)) pine, native to eastern North America. This species occasionally hybridizes with other pine species such as loblolly pine (Pinus taeda), shortleaf pine (Pinus echinata), and pond pine (Pinus serotina); the last is treated as a subspecies of pitch pine by some botanists.

Structure [2]  Tree
Usage [2]  A tan or green dye is obtained from the needles; The needles contain a substance called terpene, this is released when rain washes over the needles and it has a negative effect on the germination of some plants, including wheat; Smoke from the burning leaves has been used to get rid of fleas; The tree is a good source of resin but it is not exploited commercially; Oleo-resins are present in the tissues of all species of pines, but these are often not present in sufficient quantity to make their extraction economically worthwhile; The resins are obtained by tapping the trunk, or by destructive distillation of the wood; In general, trees from warmer areas of distribution give the higher yields; Turpentine consists of an average of 20% of the oleo-resin; Turpentine has a wide range of uses including as a solvent for waxes etc, for making varnish, medicinal etc; Rosin is the substance left after turpentine is removed. This is used by violinists on their bows and also in making sealing wax, varnish etc; Pitch can also be obtained from the resin and is used for waterproofing, as a wood preservative etc. The knots contain so much resin that they resist rot. They burn well and have been gathered and placed at the ends of sticks to make torches; Wood - coarse-grained, light, soft, brittle, not strong, very durable, resinous; It weighs 32lb per cubic foot; Mainly used for charcoal and fuel, it is occasionally sawn into lumber;
