192 PINUS ; OR 



A large tree, growing sixty or seventy feet high, in the moun- 

 tains of TenerifFe, and on the Grand Canary Island, at an ele- 

 vation of 5,000 or 6,000 feet, where it forms extensive forests, 

 from the sea shore to an altitude on the mountains of 6,000 feet. 

 It is most abundant at elevations of from 4,000 to 6,000 feet 

 above the level of the sea ; on the Grand Canary Island the 

 pine forests extends from Oratava to Portillo de la Villa. 



Timber, resinous, durable, and free from the ravages of 

 insects. 



It is tender. 



No. 27. PiNUS CEMBROiDES, Gordou, the Mexican Cembra-like 



Pine. 

 Syn. Pinus edulis, WisUzenus. 



Leaves, in threes, from one inch to one inch and a half in 

 length on the wild specimens, but rather longer on the young 

 growing plants ; tolerably rigid, slightly twisted at the base, 

 three-edged, very dense, and of a bright glaucous green colour ; 

 sheaths, short, and soon falling off, or curling up. Seed-leaves, 

 on the young plants, from ten to twelve in number when the 

 first come up. Branches, vertical, mostly in fives, but some- 

 times more numerous in a whorl, rather slender, slightly 

 incurved, and spreading, with tolerable smooth bark, and re- 

 markably small buds, which are imbricated and non-resinous, or 

 nearly so. Cones, single, and stalkless ; from two inches and a 

 half to three inches in length, and one inch and three quarters 

 broad at the base, with six or seven rows of scales, and tapering 

 but slightly to a blunt point ; the scales are rounded at the 

 margins, three quarters of an inch broad, slightly elevated, and 

 nearly all of a size, except those close to the base, which are 

 very much smaller, and more elevated ; each scale contains 

 within it two wingless seeds, which are top-shaped, slightly 

 angled at the smaller end, about half an inch in length, and 

 rather thin shelled. 



This Pine resembles Pinus Llaveana in general appearance, 

 but differs in having shorter, more glaucous, and smaller leaves, 

 and with cones three or four times the size of those of P. Llaveana,
