A tree of ponds and swamps, reaching a maximum height of about 75° and a trunk diameter of 30, its trunk usually short, the bark fissured into small plates. Leaves in 3's (rarely some in 4's), pale green, glaucous, 6'-io' long, with 2 nbro-vascular bundles; sheaths about ¥ long; cones ovoid to globular- ovoid, about 2I' long, the scales bearing a slender, incurved, usually deciduous prickle. Atlantic coastal plain, southern New Jersey; Virginia to Florida. Wood soft, brittle, coarse- grained; weight per cubic foot about 49 lbs. Pinus sylvestris L., the Scotch Pine, of northern Europe, which resembles P. resinosa Ait. in having two needles to each sheath and unarmed cone-scales, is much planted for orna- ment and has become established on the coasts of Maine and Massachusetts. 2.

Anther-sacs 2-celled, the sacs transversely or obliquely dehiscent. Pollen-grains simple. Cones ovoid or cylindric, small, erect, their scales thin, spirally arranged, obtuse, persistent. Ovules 2 on the base of each scale, ripening into 2 reflexed somewhat winged seeds. [Name ancient, probably Celtic] About 9 species, natives of the north temperate and subarctic zones.
