The "spray" (formed from the flat branchlets) is itself flat and very delicate and of a dull green. Cones - about one fourth of an inch in diameter, round, variously placed, compact, purplish as they ripen; opening when ripe toward the centre line (i. e., not toward its base). Scales - fleshy, shield-shaped and apparently fastened near their centres, with the edge several-pointed, and with a sharp point or knob in the centre. Seeds - usually four to eight under each scale, oval, with wide wings at the sides. Found - in deep, cold swamps (filling them densely and exclusively), from Southern Maine along the coast to Florida, and along the Gulf coast to Mississippi. General Information - A tapering evergreen tree, thirty to seventy feet high, with light and durable wood, largely used in boat-building, for wooden-ware, shingles, etc.
