PRACTICAL FORESTRY. 



States, but will probably succeed south of the latitude of Wash- 

 ington. 



T. grandis, Fortune. — Tall Torrej^a. — Leaves slightly shorter 

 than the last, slightly convex above. Fruit plum-shaped, and 

 about three-quarters of an inch long. This species is scarcely 

 distinguishable from the last. Native of China and the Hima- 

 layas. A tree forty to fifty feet high. 



The Chinese Yews, or Cephalotaxus, of which there are two 

 or three species, would naturally fall into this group, but we 

 have no representatives nearer than the Torreya's in our flora. 



The Podocarpece, evergreen trees and shrubs, pecuHar to the 

 warmer regions of Australia, Africa, and Asia, belong to this 

 order, but only a few are' of any special interest, except for or- 

 namental purposes. The Japanese species (P. Japonica) Sie- 

 bold, thrives moderately well as far north as New York, and is 

 an interesting plant on account of its very dark, rigid leaves. 

 There is also a South American species (P. nuhigcend), that 

 promises to be even more hardy than the one from Japan, as it 

 is a native of the cool regions of Chili and Patagonia. 



The New Zealand Pines, or Dacridiums, also belong to this 

 order, as they bear drupaceous fruit, like that of the Yews. 

 Some are large trees, and the wood very hard and durable. They 

 may prove valuable for cultivation in our Southern States and 

 westward. 



Another very interesting genus of this order is represented 

 by only a single species, and that the well known Ginkgo or 

 Maiden Hair Tree, or Salisbury adiantifolia, sl native of China 

 and Japan, and a tree that grows to a very large size, or in some 

 situations a hundred feet high, with stem five to ten feet in 

 diameter. Its leaves are deciduous, fan-shaped, very broad, and 

 cut or notched at the apex. Its fruit is a globular ovate, and 

 an inch in diameter. It is a well known hardy tree, introduced 

 into this country a century ago, or in 1784, by Alexander Ham- 

 ilton, who planted specimens near Philadelphia, which are said 

 to be still alive and growing. There are several varieties, but 

 none that are really more beautiful than the species.
