A noble tree, growing 130 feet high, with a straight trunk, 

 furnished with long slender branches, in regular whorls, and 

 pendent branchlets two or three feet long, which give the tree 

 a most perfect and elegant appearance. 



It is found growing in the department of Durango, on the 

 Sierra Madre, a chain of mountains situated between the Table 

 Land and Gulf of Mexico, where it is known by the name of 

 " Pino Keal," or Royal Pine, a name due to its great size and 

 majestic appearance. It is also found on the eastern side of 

 Popocatepetl, at an elevation of from 11,000 to 12,000 feet, 

 and like Pinus Lambertiana, it produces a resinous substance, 

 which when dried and pounded becomes a kind of ash-coloured 

 powder, very sweet, and eaten by the inhabitants instead of 

 sugar. 



It is tolerably hardy.
