winged elm or wahoo, of the southeastern United States. 

 The American elm and the slippery elm are wild in the 

 grounds. The hackberries (Celtis) represented are the 

 Georgia hackberry, the dog hackberry, and Small's hack- 

 berry, of the southeastern United States; and the nettle- 

 tree, or sugarberry, of eastern North America. The 

 water-elms are illustrated by the sharp-pointed water- 

 elm, or Zelkova, a native of Japan. The mulberry family 

 (Moraceae) is represented by the osage orange (Toxylon), 

 a native of the south central parts of the United States, 

 trees of which may be found to the south of the drive- 

 way from the long bridge; and by the Russian red and 

 white mulberries. The kadsura tree family has for its 

 representatives the kadsura tree, of Japan, and the elm- 

 leaved eucommia, of China, located just to the south of 

 the row of large tulip trees east of the Bronx River. 



The magnolia collection is planted on the west and south 

 sides of the swale between the two ridges. The long- 

 leaved umbrella tree is one of those to be seen here; it is 

 a native of the mountain woods from Virginia to Florida and 

 Mississippi. The cucumber tree, the white-leaved Japa- 

 nese magnolia, the umbrella tree, and a number of hybrid 

 forms are other magnolias to be looked for here. Large 

 specimens of the umbrella tree and of the large-leaved um- 

 brella tree will be found at the north end of the herbaceous 

 grounds, on the west side; and still other species at the 

 fruticetum. The tulip-tree is shown by a row of fine wild 

 specimens just to the south of the long bridge over the 

 Bronx River, the largest trees within the grounds of the 

 Garden. This tree is native of the eastern United States 

 and yields a valuable lumber known as yellow poplar or 

 white-wood; the Indians formerly made their canoes from 

 this wood. Four parallel rows of this tree form part of 

 the approach to the museum building. Related to the 

 magnolias is the custard-apple family, represented by two 

 specimens of the North American papaw, which will be 

 found at the herbaceous grounds on the west side, near
