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. 7’. Calfornica 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 7. 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. Fortunei 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. alpima (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 foliage, growth habit, and 
form. ‘The changeableness of color in the foliage, 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. 
1. 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
