THE TRUE PINES. 231 



base of the cone, where they are sometimes quite reflected, and 

 much narrower ; thickest in the centre, and tapering to a broad 

 more or less reflexed point, with several elevated lines on the 

 surface. Seeds, very large, with a broad ample wing, one inch 

 long. 



A noble tree, rivalling Pinus Lambertiana, and growing 1 40 

 feet high, with a straight stem, furnished with long slender 

 branches in regular whorls and pendant branchlets, two or 

 three feet long. 



It is found on the east side of Popocatepetl in Mexico, at an 

 elevation of from 11,000 to 12,000 feet; also at * Tenango,' a 

 beautiful tree, with large pendant cones at the points of the 

 shoots, very much resembling Pine- apples, and called by the 

 Mexicans, * Pina.' It is also called ' Ayacahuite Colorado,' or 

 Red Ayacahuite by the inhabitants, on account of its highly- 

 esteemed timber, which is of excellent quality. 



This kind is very distinct from Pinus Ayacahuite, of Ehren- 

 berg, as I pointed out several years ago in the ' Gardener's Ma- 

 gazine,' after examining cones belonging to the late Mr. Lou- 

 don, 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 valuable 

 book of its kind ever published. 



It no doubt will be hardy, coming, as it does, from so great 

 an elevation, and a cold climate. 



No. 76. Pinus macrophylla, Lindley, the Long-leaved 



Mexican Pine. 



Syn. Pinus Leroyi, 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, not 

 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
