Cornus controversa. Dogwood Family. P. 36. This species 
and the American Cornus alternifolia are the only dogwoods with 
alternate leaves. Its wide-spreading, horizontal branches are pro- 
duced in tiers. Because of its interesting way of branching, its 
good foliage and white flowers in May it makes a good lawn 
specimen. China, Japan. 
Cornus macrophylla. Dogwood Family. P. 36. A small tree. 
Cos 
somewhat like Cornus controversa. The long-pointed leaves are 
large, often exceeding seven inches in length, and in late June the 
tree 1s very attractive with its broad clusters of white flowers. 
China, Japan, Himalayas. 
Cornus Waltert. Dogwood Family. P. 36. Though quite dif- 
ferent in habit and not so handsome as the preceding species, it is 
nevertheless an interesting and worth while small tree. China. 
Oxydendrum arboreum. Sorrel-Tree or Sourwood. Heath Fam- 
ily. P. 36. Another tree that blooms in mid-summer. In July the 
small white flowers are carried 
— 
1 drooping branched clusters. 
The foliage of this slender tree, which reaches its best development 
in the mountains of Tennessee, is dark glossy green and in the 
fall becomes brightly colored. A handsome small tree that de- 
serves wider appreciation. Being a member of the Heath Family 
it requires a lime-free soil. Much planted along the Hutchinson 
River Parkway, Westchester County, N. Y. Pennsylvania to 
Louisiana. 
Pterostyrax corymbosa. Epaulette Tree. Storax Family. P. 37. 
A vigorous tree with rather coarse, light green foliage. The white 
flowers are so arranged in the pendulous clusters that they resemble 
a series of epaulettes. Japan. 
Ehretia thyrsifora. Borage Family. P. 38. Ehretia has small 
white flowers and coarse follage. It is grown here mainly for 
botanical interest, for it 1s the only member of the Family to become 
a tree in this climate. China, Japan. 
Catalpa Fargest. Bignonia Family. P. 38. In its native habitat 
this Catalpa is a tall tree. In Brooklyn it is more or less shrubby, 
and so far has not produced its flowers, which are unusual in 
yeing pink. China.
