JUNIPERACEAE. 3 



crowded; sheaths about 15 mm. long: staminate aments 1.5-2 cm. long: cones 

 4-6 cm. long, ovoid or globular-ovoid when closed, very broad when open, each 

 scale with a thick appendage and a minute spine: seeds 3-4 mm. long, the 

 wing nearly 2 cm. long. 



The Pond-pine grows in swamps and shallow ponds in eastern Florida. The 

 orange-colored heart-wood is coarse-grained, soft, heavy, and brittle. Also known as 

 Black-pine or Marsh-pine. (Cont.) 



6. P. glabra Walt. Tree becoming 40 m. tall, the trunk with a relatively 

 smooth bark and often with spreading branches near the base: leaves in 2's, 

 glaucous, 4-8 cm. long, very slender; sheaths 5-8 mm. long: staminate aments 

 about 1 cm. long: cones 3.5-5 cm. long, conic when closed, ovoid when open, 

 each appendage with a minute or almost obsolete spine : seeds about 4 mm. long, 

 the wing usually 1.5 cm. long. 



The Speuce-pine grows in rich soil in river-swamps or hammocks in northern 

 Florida and the upper part of the peninsula. The pale-brown heart-wood is close- 

 grained, light, soft, and brittle. Sometimes known as Cedar-pine or White-pine. 

 (Cont.) 



7. P. echinata Mill. Tree becoming 40 m. tall, the bark very rough and 

 coarsely furrowed : leaves in 2 's or rarely in 3 's, deep-green, 8-12 cm. long, 

 slender ; sheaths 10-15 mm. long : cones 5-6.5 cm. long, conic when closed, ovoid 

 when open, each scale-appendage armed with a slender spine: seeds 4-5 mm. 

 long, the wing 1.5-2 cm. long. 



The SnoitT-LEAF PINE grows in sandy soil in northern Florida. The yellowish 

 or orange-colored heart-wood is coarse-grained, hard, heavy, and rather strong. Also 

 known as Yellow-pine. (Cont.) 



8. P. clausa (Engelm.) Vasey. Tree becoming 24 m. tall, the bark relatively 

 smooth: leaves in 2's, deep-green, 4-8 cm. long, very slender; sheaths 5-7 mm. 

 long: cones 4.5—6 cm. long, conic when closed, ovoid when open, each scale- 

 appendage with a stout spine at the middle or behind it: seeds 4 mm. long, the 

 wing about 1.5 cm. long. 



The Sand-pine grows in sand locally throughout Florida, except the extreme- 

 southern part. The yellow or orange heart-wood is rather close-grained, soft, light, 

 and weak. Also known as Spruce-pine. Grows naturally outside of Florida only ia 

 adjacent Alabama.
