 green, of different forms : in the 

 young tree, vertically compressed, 

 divaricate and spreading, 2-rowed 

 in a quincunx manner, linear- 

 awl-shaped, spinulose and mucro- 

 nate, straight, rigid, decurrent at 

 the base, in. long ; in the full- 

 grown tree horizontal, and in a 

 close spiral, incurved, loosely 

 imbricated, lanceolate from the
