A tree, attaining 30 to 40 ft. in height, with brown bark separating into thin 

 scales ; branches widely spreading, with long pendulous branchlets. Leaves 

 dimorphic. Adult foliage : leaves in opposite decussate pairs, slightly spreading, 

 ovate-lanceolate, about ^ in. long, decurrent, ending in a sharp cartilaginous point, 

 rounded on the back, which is marked with a linear sunken gland, often exuding 

 resin. Juvenile foliage, usually on the ends of some branchlets of adult trees, 

 acicular-subulate, spreading, usually in whorls of threes, rarely in pairs, decurrent, 

 about in. long, gradually tapering from the base to the very sharp cartilaginous apex ; 

 upper surface concave, with inflexed margins, and with two narrow stomatic lines ; 

 lower surface marked near the base with a linear gland, often exuding resin. Similar 

 spreading acicular leaves, in pairs or in threes, are borne on the main axes of the 

 branchlet-systems, and like these turn reddish brown in the third and fourth year, 

 and fall in succeeding years, leaving the branchlets smooth with a scaly bark. 



Flowers monoecious. Fruit, ripening in the second year, on a short ( T ^ in. long) 

 scaly stalk, four- to six-bracteate at the base, sub-globose, about \ in. in diameter, 

 reddish brown with a glaucous bloom, and marked on the surface with a few minute 

 tubercles ; composed of six to eight opposite scales, each indicated by a reflexed 

 triangular mucro. Seeds, six to twelve, several often aborted, embedded in a 

 resinous pulp ; cotyledons two. ' (A. H.) 



This species is a native of Texas and Mexico. It is limited in Texas to the 

 Chisos Mountains, where it was discovered in 1888 by Dr. V. Harvard. It is 

 common in north-eastern Mexico, at elevations of 6000 ft. to 8000 ft., on the hills to 

 the east of the tablelands, ranging from Coahuila to Oaxaca, and extending eastward 

 to about a hundred miles from the coast. 



It was introduced 1 in 1838 from Mexico by Hartweg, but is probably too 

 tender for our climate in most parts, as the only specimen which we know of in 

 Britain is a fine tree at Bicton, which I found to be about 40 ft. by 3 ft. 10 in. 

 in 1906. It grows in a sheltered hollow, and bears fruit regularly, which is smaller 

 in size than in native specimens, and contains only imperfect seed. 



Carriere states 2 that it is not hardy at Paris, but he mentions a tree at Angers
