(Toxylon), trees of which may be found to the south of the 

 driveway from the long bridge; it is a native of the central 

 parts of the United States; and by the Russian, red and 

 white mulberries. The cercis-leaf family has for a repre- 

 sentative the cercis-leaf, of Japan, 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. Fraser's magnolia 

 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 Japanese 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 umbrella 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 the north end; this is a native of the 

 eastern part of the country, from Ontario and New York 

 to Michigan, Nebraska, Florida and Texas. The laurel

 may be found wild in various parts of the Garden. The 

 sweet gum (Liquidambar), also wild in the grounds, repre-

The plane-trees are to be found just to the west of the 

 elms. Here are specimens of the American plane-tree;
