THE TRUE PINES. 221 



No. 63. PiNUS CORNEA, Roezl, the Horn- shaped Coned Pine. 



Leaves, in fives, rather long, and slender. Cones, somewhat 

 like those of Pinus Pseud o-Strobus, long, recurved, tapering 

 from the base to a small point, quite firm, and resembling a 

 small cow's-horn. It is found on the Popocatepetl, in Mexico, 

 at an elevation of from 10,000 to 11,000 feet. 



It appears to be quite new, and distinct. 



No. 64. PiNUS Devoniana, Lindley, the Duke of Devonshire's 



Pine. 

 Syn. Pinus Blanco, Knight. 



Leaves, in fives, very long, but rather slender and pendulous, 

 of a beautiful deep shining grass-green, from eight to nine 

 inches long, and rather sharp-pointed. Sheaths, very long, 

 rough at the end, imbricated, and one inch long. Branches, 

 very robust, few, and very irregular, and like those of the 

 Swarp Pine of the United States (P. palustris). Cones, from 

 nine to ten inches long, and three inches in diameter near the 

 base, tapering to a blunt point, three quarters of an inch wide, 

 solitary, pendulous, curved, blunt-pointed, and not very firm or 

 hard on the surface. Scales, rather thin, one inch broad, but 

 smaller towards both ends, rounded at the top, and irregularly 

 four-sided, with a slightly elevated transverse line and project- 

 ing point in the centre, which is depressed and smooth. Seeds, 

 rather small, with the wing nearly one inch and a half long. 



A large tree, growing from sixty to eighty feet high in the 

 mining districts of Mexico, on the mountains of Ocotillo, between 

 Real del Monte and Regla, and on the ' Cumbra,' or highest 

 point of the mountains. It is called by the inhabitants ' Pino 

 Blanco,' or the White Pine, on account of its timber being that 

 colour, and ' Pino-real,' or Royal Pine, from its noble appear- 

 ance and splendid long foliage. 



Mr. Hartweg first discovered it in Mexico in 1839. 



It is tolerably hardy.
