THE TRUE PINES. 245 



No. 96. PiNUS Cedrus, Roezl, the Cedar-like Mexican Pine. 

 (Discovered by M. Roezl in 1856-7.) 



Leaves, in fives, glaucescent, three-edged, and from three to 

 four inches long. Sheaths, very deciduous, or falling off quickly 

 •when young. Cones, two inches long, and rather more than 

 one inch in diameter. Scales, irregularly shaped, sometimes 

 rounded or flat; protuberance flat, and armed with a thorny 

 spine, tolerably elevated at the base and towards the apex of 

 the cone. 



This tree very much resembles the Cedar of Lebanon when 

 viewed from a distance ; not having the least appearance of being 

 a true Pine when seen in such a situation. It grows upwards 

 of sixty feet high, with spreading branches, which commence 

 near the ground, and cover the trunk so as to form a regular 

 pyramid from the base, shading a space of 130 feet in diameter 

 on the ground. It grows on the mountains of Cuernavaca in 

 Mexico, at an elevation of 8,000 feet. ( ? Pinus leiophylla.) 



No. 97. Pinus coarctata, Roezl, the Contracted Mexican 



Pine. 



(Discovered by M. Roezl in 1856-7.) 



Leaves, in fives, a little stiff, three-sided, and from six to 

 eight inches long. Sheaths, from three quarters to one inch 

 long, and scaly. Cones, slightly bent, from five to six inches 

 long, and one inch and three quarters broad. Scales, rhomboid, 

 rounded on the top, three quarters of an inch broad, and rather 

 more than half an inch long ; protuberance very broad, elevated 

 in the centre, and terminated in the middle with a stout sharp 

 point. 



A tree from seventy to ninety feet high, with a very straight 

 stem, and horizontal branches, a little elevated towards the 

 points.* It is found growing upon the mountain of Tzompoli, 

 in Mexico, at an elevation of 8,000 or 9,000 feet.
