The leaves are broad, pointed, flat on the 



upper surface, and forming a ridge below ; 



of a fine light green, with a sheath long 



and whitish at first, but becoming short, thick, 



and brown when old. The cones are about 

 4 in. in length ; 

 and the scales ter- 

 minate in pro- 

 cesses which have 

 the form of an 

 elongated pyra- 

 mid, somewhat in 

 the manner of P. 

 Pinaster ; but the 

 apex of the pyra- 

 mid terminates in 

 a thick and sharp 

 prickle, somewhat 

 in the manner of 

 P. pungens, and 

 turned upwards. 

 In England, in the 

 climate of Lon- 

 don, Pinus 7ae\la 

 grows vigorously ; 

 there being large 



trees at Syon and at Kew, which, after being 50 years planted, produce 



shoots of from 9 in. to I ft. every year, and ripen cones.
