524 EVERGREEN TREES AND SHRUBS. 



dark green " (Gordon). Found in Mexico at elevations nine thou- 

 sand feet above the sea. Half-hardy, perhaps hardy. 



PINON, OR NUT PINE. P. edulis. A small-sized, short-leaved 

 mountain pine of California, which promises to be hardy, and may 

 prove interesting. Height twenty-five to forty feet. 



THE HEAVY WOODED PINE. P. ponderosa. A California 

 tree of great size, and coarse, rapid growth. Branches in regular 

 whorls, but twisted and tortuous, rising from the trunk at an angle 

 less than a right angle, drooping towards the middle and rising at 

 the ends. They are quite large and rope-like, and not being well 

 concealed by leaves, except near the extremities, give the tree the 

 appearance of a very bony frame illy clothed. It proves perfectly 

 hardy at Rochester, where Ellwanger & Barry have a fine specimen 

 thirty feet high and twenty feet in diameter across the branches. 

 It is a curious, but far from a handsome tree. 



JEFFREY'S PINE. P, Jeffreyana. One of the lofty pines of 

 northern California, where it attains a height of one hundred and 

 fifty feet. Not yet thoroughly tested on the Atlantic slope. Young 

 specimens look like a cross between the Austrian and Pyrenean 

 pines. The leaves are longer and warmer toned than those of the 

 Austrian pine. 



LAMBERT'S PINE. P. Lambertiana. This is another of the 

 lofty trees of California. It resembles our white pine so much 

 that common observers would suppose it the same. We have 

 seen no quality that should cause it to be recommended for plant- 

 ing ; our white pine being its equal or superior in all respects. 



THE MEXICAN FOUNTAIN PINE. Pinus patula. H. W. Sar- 

 gent says of this : " Of all the pines which we have seen, this is 

 beyond measure the most graceful and charming, not only in its 

 growth and habit, but in the nature, softness, and color of its 

 leaves. It resembles a beautiful, delicate green fountain of spun 

 glass, and has a parti-color like shot silk, which catches the sun-
