The Jersey Pine is usually a tree of medium 

 stature, rarely more than 40 or 50 ft. in 

 height, or of greater thicivness of trunk than 

 18 in. In the western part of its range, how- 

 ever, particularly in southern Indiana, it 

 sometimes attains twice the above dimensions. 

 It develops a rather irregular wide rounded 

 top of long and somewhat pendulous branches, 

 though when young the trees are more of a 

 pyramidal habit of growth. It is readily dis- 

 tinguished by its short twisted leaves dis- 

 tributed in pairs along its purple branchlets. 

 The bark of trunk is dark reddish brown, rough 

 with scaly irregular plates and ridges. The 

 tree has little to recommend it from an orna- 

 mental or economic standpoint, its chief point 

 of merit being the facility with which it 

 propagates itself and covers neglected worn 

 out agricultural land with new forest growth. 



The wood is rather light, soft, not strong, 

 brittle and of a light reddish brown color with 

 abundant lighter sap-wood. A cubic foot when 

 absolutely dry weighs 33.09 lbs. It is used for 

 fuel and occasionally for lumber for general 

 construction purposes.2 



Leaves in remote clusters of 2, with small per- 

 sistent sheaths, 1% to 2% in. long, dark green, 

 stout, spreading, more or less curved and twisted, 

 with many rows of stomata, 2 fibro-vascular 

 bundles and resin-ducts in parenchyma ; braneli- 

 lets flexible and distinctly purple in color. 

 Floicrrs: staminate orange-brown, in crowded 

 clusters ; pistillate pale and rose color, single or 

 few together, with long stalks lateral upon the 

 branchlets. Coucs few, narrow ovoid, 2-.'? in. long 

 with scales thickened at apex and provided with 

 a prickle ; seeds compressed ovoid, nearly i/4 in. 

 long and with ample wing broadest at about the 

 center.
