from 60 to 80 feet high, with very long, slender, light 

 green leaves, and, according to Gordon, " has the longest 

 and finest foliage of any kind yet known." 



62, P, Grcnvilleae, Gordon. Is likewise one of 

 Hartweg's discoveries, with splendid long, dark green 

 leaves, and a very robust habit of growth. It was first 

 detected in the same locality as the preceding, and attains 

 about the same height. 



63, P, Hartwegii, Lindley. Is from the Campanario 

 Mountain, in Mexico, where it was first found by Hart- 

 weg, growing from 40 to 50 feet in height. On the Ori- 

 zaba Mountains, however, it frequently attains the height 

 of 100 feet. 



64, P, leiophylla, Schiede. Is a handsome, smooth- 

 leaved pine with a regular form, and is found growing in 

 the colder regions of Mexico, where it attains the height 

 of from 60 to 100 feet. The wood is very hard and 

 resinous. 



65, P. Lindlcyana 9 Gordon. Is from the mountains 

 of Mexico, growing about 50 feet in height. Leaves, 

 rather long, stout, and of a dark green color. Although 

 quite hardy in England, it is not so with us. 



66, P. Loudoniana, Gordon. Is one of the newer 

 introductions from Mexico, where the trees are said to 

 grow to an immense size. Leaves, very stout, of medium 

 length, and quite glaucous. Cones, very large and straight, 

 from 12 to 14 inches long, and from 3 to 4 inches in diam- 

 eter. Seeds, very large. 



67, P, macrophylla, Lindley. A beautiful Mexican 

 pine with dark green leaves, about 14 inches in length. 

 The tree, however, is of only medium size, but compact 

 and striking in its habit. Discovered by Hartweg.
