312 PINUS, OE 



This kind is very distinct from the Pinus Ayacahuite, of 

 Ehrenberg, as I pointed out several years ago in the " Gar- 

 dener's Magazine," after examining cones belonging to the late 

 Mr. Loudon, and collected by Mr. Charles Ehrenberg, in Mexico. 



It has been named in compliment to the late J. C. Loudon, 

 Esq., author of the " Arboretum Britannicum," the most valu- 

 able book of its kind ever published. 



It no doubt will be quite hardy in the West of England, 

 coming, as it does, from so great an elevation, and a cold 

 climate. 



No. 78. Pinus macrophylla, Lindley, the Long-leaved 



Mexican Pine. 



Syn. Pinus Carrieri, Roezl. 

 Leroyi, Roezl. 

 Pawlikowskiana, Roezl. 



Leaves in fives, very stout, fourteen or fifteen inches long, 

 deep green, and slightly reflexed when full-grown, blunt- 

 pointed and quite straight when young. Sheaths not very 

 long, imbricated, and persistent. Branches very robust, jiot 

 numerous, but rather regularly placed round the stem, and 

 covered with a rough, scaly bark. Cones solitary, six inches 

 long, and three inches broad at the base, very hard, elongated, 

 straight, and regularly tapering to the point, with a thick but 

 short foot-stalk. Scales greatly elevated, and hooked back- 

 wards, very hard and glossy, irregularly four-sided, broader 

 than long, and one inch wide, but much narrower and more 

 reflexed near the base, and straight-pointed near the summit. 



A tree from 100 to 130 feet high, growing in the forests of 

 Tulancingo in Mexico, at an elevation of 8000 or 9000 feet. 



Mr. Hartweg found it but sparingly on the Ocotillo Mount, 

 one of the highest points of the Angangueo Mountains in 

 Mexico. 



It is tolerably hardy in most parts, and a most beautiful 

 kind, on account of its fine, ample foliage.
