THE TRUE PINES. 313 



No. 79. Pmus Montezuma, Lambert, Montezuma's Mexican 



Pine. 



Syn. Pinus Occidentalis, Humboldt and Bonpland, not Swart:, 

 Endlicheriana, Roezl. 

 inflexa, Roezl. 

 Lowi, Roezl. 

 Wilsoni, Roezl. 



(The Rough-barked Pine of Mexico.) 



Leaves in fives, from three to four inches in length on the 

 wild specimens, and on young plants from four to five inches 

 long ; rather stout, rigid, three-edged, and rough at the angles, 

 thickly set upon the young branches, and supported by long, 

 sharp-pointed, brown scales at the base of each sheath, of a 

 dark green on the upper surface, and slightly glaucous on the 

 under side, on the young leaves, but on old, full-grown leaves 

 dark green on both surfaces. Sheaths persistent, or not falling 

 off, nearly half an inch in length, and rather rough or jagged 

 on the ends. Seed-leaves on the young plants from six to 

 eight in number. Branches few, very irregular, rather stout, 

 and twisted. Bark very rough, particularly on the young wood, 

 which is covered with numerous long, broad, sharp-pointed 

 scales. Buds few, imbricated, non-resinous, and rather length- 

 ened. Cones in clusters of three or four together, but fre- 

 quently single, nearly horizontal, from four to five inches in 

 length, and one inch and three-quarters in the broadest part, 

 which is near the middle, tapering to both ends, and 

 slightly incurved, but especially towards the point, which 

 is rather small. Scales small, and nearly equal in size, from 

 sixteen to eighteen rows in depth, slightly elevated, and armed 

 with a small prickle when young. Seeds small and winged. 



This Pine is very distinct, both in cones and leaves, from the 

 West India Pine, called P. Occidentalis by Swartz, a kind 

 found in Cuba and other West India Islands, which is quite 

 tender, and much smaller in its cones, and foliage, than the 

 Mexican plant.
