Acacias and False Acacias 247 



T. Canadensis Marsh. (79), a prostrate shrub of our northern woods, 

 which grows to a beautiful specimen when developed in nursery rows. 



Torreya. T. Calif ornica Torr. (80), the California Nutmeg Tree, and 

 T. taxifolia Arnott (81), from Florida, are two small trees of the yew 

 type, neither of them hardy in northern climates; with interesting, 

 sharp-pointed foliage, and open, stately form. They are insect- and 

 fungus-proof. The Japanese T. nucifera S. & Z. (82) is probably 

 hardier than the native ones. 



Cephalotaxus, a genus with several species of small trees and shrubs 

 from Japan and China, is mainly fit for southern planting, but possibly 

 hardy as far north as Philadelphia. The best, C. Fortiinei Hook (83), 

 is of highly ornamental aspect and more graceful habit than the true 

 yews, its sharp-pointed foliage being of livelier color. 



Podocarpus, a genus with more than forty species of small trees, of 

 tropical and sub-tropical mountainous range, is fit only for southern 

 planting, although P. alpina (84), the hardiest, may be grown as far 

 north as Philadelphia. 



B. BROAD-LEAF TREES 



The ornamental value of the broad-leaf trees is to be 

 sought mainly in the variety of fohage, growth habit, and 

 form. The changeableness of color in the fohage, the vari- 

 ety of tints in the fall, and again in early spring upon the 

 reawakening of Nature, and the variety of branch systems 

 in their naked winter condition furnish unending attraction, 

 both in the single tree, allowed to grow in perfect form, and 

 in the properly grouped clump. A number, especially of 

 the low trees, are also attractive by their flowers, which 

 in most of the tall ones form only a very passing interest. 



I. BROAD-LEAF TREES WITH COMPOUND LEAVES 



ACACIAS and FALSE ACACIAS (Locusts) 



We may consider together under these names four genera of the 

 Pulse family, — Acacia, Albizzia, Robinia, Gleditschia — with some
