194 PINUS; OR 



A fine tree, common on the higher mountains of Cosihuiriachi^ 

 in North Mexico, growing seventy or eighty feet high, very 

 much resembling the Swamp Pine of the United States, but 

 differs in having much smaller cones, and in the leaves being 

 in three, four, and five in a sheath. 



No. 30. Pin us Fuemontiana, Endlicher, Colonel Fremont's 



Nut Pine. 

 Syn. Pinus monophylla, Torrey. 

 „ ,, Llaveana, with a thin-shelled seed, Hartweg. 



Leaves, generally in threes, but not unfrequently in pairs, 

 or singly, from one inch and a half to three inches in length, 

 of a glaucous green, more or less curved, very stout, rigid, and 

 ending in a spiny point. Sheaths, very short, and rolled back- 

 wards on the older leaves. Seed-leaves, from eight to ten, but 

 mostly nine in number, rather long, and very stout. Branches, 

 numerous, the principal ones round the stem in whorls. 

 Bark, smooth, and of a light brown colour. Buds, small, 

 cylindrical, and three-quarters of an inch long. Cones, of 

 a light glossy brown colour, two inches and a half long, and 

 one inch and three-quarters broad, in the widest part, which 

 is near the middle ; each cone contains from six to seven 

 rows of scales. Scales, very thick, largest near the middle, 

 bluntly pyramidal, slightly angular, and more or less recurved 

 downwards, particularly the smaller ones nearest the base ; 

 they are also without any points. Seeds, wingless, oblong, or 

 egg-shaped, half an inch long, bright yellow, more or less 

 stained with dark brown, and the shells so thin, that it is very 

 easily broken between the finger and thumb. Kernel, very 

 pleasant in flavour, and also nutritious, as it constitutes the 

 principal substance of the Indians who live in the mountains, 

 where it grows for nine months out of the twelve. It was first 

 discovered by Colonel Fremont during his exploring expedition 

 when crossing the Sierra Nevada, or Great Californian Moun- 

 tains, growing upon both sides, and extending over the top of 

 the great snowy chain for a distance of 300 miles; the tree
