PINE FAMILY. 335 



POOR OR DESTITUTE PINUS. Jersey or Scrub Pine. 



Stem 15-40 feet high, with straggling branches. Leaves \% to near 3 inches long, 

 Staminate aments oblong-ovoid, violet-purple. Cones 2-4 inches long. 

 Barren hills, &c. New Jersey, southward. 



06s. The wood of this tree is said to be of but little value. 



2. P. resino'sa, Ait. Leaves from long sheaths, semi-cylindrical; 

 scales of the cones pointless. 



RESINOUS PINUS. Red Pine. 



Trunk 70 - 80 feet in height and of a nearly uniform diameter for two-thirds of its length ; 

 the bark reddish. Leaves 5-6 inches long, dark green. Cones about 2 inches long, some- 

 times in clusters. 



New England to Pennsylvania, north and west. 



06s. This tree is known in New England as the Norway Pine, a 

 name which is applied in Europe to quite another tree. The wood is 

 valuable, though less so than that of the Pitch Pine. 



3. P, mi'tis, MX. Leaves in pairs, often in threes, slender, channelled, 

 from long sheaths ; cones ovoid-conical, small ; scales with a small, weak 

 prickle. 



SOFT PINUS. Yellow Pine (of the North). 



Stem 40 - 60 or 80 feet high, and 1-2 feet or more in diameter, with the bark in rather 

 broad flat scales. Leaves 3- 5 inches long, slender, linear, dark green, mostly in pairs 

 (sometimes in threes, ou young branches). Strobiles (or cones) 2-3 inches long. 



New England to Wisconsin and south ; abundant in New Jersey. 



06s. This tree affords valuable lumber, and is much employed in 

 the construction of houses, and merchant vessels ; but is much inferior 

 in qualits to the Yellow Pine of the South. 



ff Leaves in threes, (rarely sometimes in fours.} 



4. P. rig'ida, Miller. Leaves rigid, from very short sheaths ; cones 

 ovoid-conical or ovate, often clustered; scales with a short and stout 

 recurved prickle. 



RIGID PINUS. Pitch Pine. 



Tmnfc30-60 feet high, rugged and knotty from the bases of fallen branches. Leaves 

 3-5 inches long, dark green, flattish. Cones 1-3% inches long. 

 Sterile soil : New England, southward. 



06s. This species in barren and sandy districts forms woods where 

 scarcely any other tree will grow. The wood is hard and filled with re- 

 sin, and when it can be obtained free from knots, it forms valuable lum- 

 ber for many purposes. It is used to some extent in ship building, and 

 largely consumed as fuel, especially for steam-engines. 



5. P. tse'da, L. Leaves long and rigid, with elongated sheaths : cones 

 oblong ; the scales with a short incurved spine. 



Loblolly or Old Field Pine.
